Windows 10 causing confusion

[Peter Gentry]

Has anyone else suffered from strange changes recently simple things like
the new and annoying way  that File Explorer now works. Other curious
artefacts such as when printing from Fresco any .eps graphic appears upside
down but the same pdf file printed directly has  the .eps  the correct way
up. I'm sure these effects are windows related and nothing really to do with
Lily or Fresco they just annoy an 80 year old intensely.  Lily as ever is
brilliant.

Re: Remote Ensemble Playing

[Peter Gentry]

Thanks for the responses. My current conclusion is that there are inherent
technical issues  that are insurmountable. If there was a good solution it
would be visible on the web.

 

My way forward is to record and distribute various pieces using midi or
YouTube downloads (if available) so that members can practice and be perfect
when we can meet up again.

 

Keep safe everyone.

Remote Ensemble Playing

[Peter Gentry]

I appreciate this is off topic but in these times of social isolation does
anyone have any tips. Clearly latency is the main issue - I wonder could
this be reduced by say hosting a Zoom meeting on a private router - maybe
only one video for a conductor. Experience suggests that a latency of 25ms
is not low enough.

Python and Visual Studio

[Peter Gentry]

It seems there is a way to switch between 3.7 and 2.7 BUT it is complex and
opaque. It needs careful downloading of Python 3.7 and some other mysterious
messing with "Shebangs" whatever they are and using strange characters such
as  Greek "lambda" (not on my keyboards). It would seem the game is not
worth the candle so 3.7 is in the dustbin and all back to normal. 

 

It is a shame though that 3.7 and Lilypond cannot co-exist easily on Windows
10 at any rate.

More convert-ly tribulations

[Peter Gentry]

Thinking I would learn more about python I installed Visual Studio.

 

Now when I try and run the batch file I get

 

SyntaxError: Missing parentheses in call to 'print'. Did you mean
print(log[0])?

Traceback (most recent call last):

  File "C:\Program Files (x86)\LilyPond\usr\bin\convert-ly.py", line 52, in


import lilylib as ly

  File "C:\Program Files
(x86)\LilyPond\usr\share\lilypond\current\python\lilylib.py", line 238

print log[0]

 

repeated for every file "updated"

 

Visual Studio has replaced my python app setting with a series of its own.

Is it at all possible to have visual studio and Lily Python on the same
machine.

I will try and alter my file type but it looks as though it is in the Lily
convert-ly.py attempt to import lilylib as ly whatever that does that is the
elephant trap.

Python seems to be a right pain with all its various invarnations it's a
wonder anything works.

re convert-ly on Windows 10 (my steps)

[Peter Gentry]

Running convert-ly on Windows10

 

1. add lilypond python to the path

 

i.  Open System Properties or  you may need to open the old control
panel

ii.Click Advanced system settings.

iii.Click Environment Variables...

iv.   Select PATH in the System variables section

v.Click Edit

vi.Add Python's path to the end of the list (the paths are separated by
semicolons).

;C:\Program Files (x86)\Lilypond\usr\bin\python.exe

 

2. At a system command admin prompt

  

i.   associate .py files with python

ii.  type  assoc .py=python

 

3. set the python.exe as the filetype for .py files

 

i. type  ftype .py="C:\Program Files (x86)\Lilypond\usr\bin\python.exe" "%1"

 

4. to run convert-ly.py put this (or similar) string in a .bat file

 

i. forfiles /s /p "C:\Users\Peter\Lilypool\Music_Files\Prout" /M **.ly /c
"cmd  /c convert-ly.py  -e @file"

ii. this could be improved if the file is edited to ask for input, either a
single file or a folder.

 

Regards Peter

 

Re convert-ly problems

[Peter Gentry]

The final piece of the jig saw was this batch file

 

 

forfiles /s /p "C:\Users\Peter\Lilypool\Music_Files\Bouffil" /M **.ly /c
"cmd  /c convert-ly.py  -e @file"

 

Getting this to work was non trivial. I will try and get a batch file to ask
for the folder "Bouffil" etc  to make updating easy. Shame that Fresco is
still deficient.

 

Thanks everyone - no one advice solved the whole thing.

Path. and assoc. were needed

convert-ly problem 2

[Peter Gentry]

Having rediscovered the fact that Frescobaldi does not call convert-ly
anymore. I went to the section 2.2 of the usage manual and popped the
following into a windows 10 command prompt (with administrator privs)

 

C:\Program Files (x86)\LilyPond\usr\bin>forfiles /s /p
"C:\users\peter\Lilypool\Music_Files\Bouffil" /M **.ly /c "cmd  /c
convert-ly.py  -e @file"

 

The result was 

'convert-ly.py' is not recognized as an internal or external command,

operable program or batch file.

Etc etc for each .ly file in the folder

 

I have cd'd to the Lilypond usr\bin folder so I don't think the three "s are
needed here, but who knows

Where did I go wrong?

 

For no particular reason I then uninstalled anaconda and python 3.8 the
result (after reboot) was that the same command string produced a response
for each .ly file in Bouffil.

The response was a pop up box saying that no app was available for that
file. The Command Prompt then froze and I needed Task Manager to close it.

 

Clearly these other pythons have interfered with Lily somewhere and may have
a bearing on my other recent issues.

 

Does anyone else play around with Python outside of Lily who might know how
to keep then separate.

The basic question here is whether LilyPond's behavior changed in a manner
that stopped previously working documents from compiling, and whether this
was something that convert-ly would have been able to fix, or should have
been able to fix but wasn't.

Re Problems with cues

[Peter Gentry]

Thanks for that response David. I wonder if the cause is to be found on my
machine rather than in Lilypond.

 

I have recently been looking at Python (to try and stimulate a few aged grey
cells) to which end I have blundered about with Trinket and also installed
Python3.8 (64bit).

These efforts have stalled since I have not found a way of including "numpy"
and "processing" outside of Trinket.

 

Could this action in anyway interfere with the Python part of the Lilypond
installation?

My problem did not appear after any Lilypond update so very unlikely to be
Lilypond related.

 

In an earlier life using a remote mainframe I stumbled on a freak problem.
The secure network had  a series of PO repeaters. These repeaters could all
be controlled centrally by the PO using  signals (not character data I
believe it was frequency modulated signalling). 

 

It transpired that my data contained one sequence of characters that were
interpreted by one faulty repeater as a shut down command. The repeater
worked correctly for 99.9% of the time for a number of sites  until it
met my innocuous string.

 

You can imagine how hard it was to convince all the technicians along the
line that the fault was in the line somewhere not my input since no other
users (there were a lot!) were affected. 

 

Some issues can be very hard to resolve.

 

Regards Peter

 

problems with cues

[Peter Gentry]

It seems that the issue reared its head as a result of my "erroneous"
assumption that

\book {

 Page layout stuff for front page

} 

\bookpart {

Header & music

}

\bookpart {

Header & music

}

Was a way to go.

 

Although this has worked over the years it doesn't today.

If I just use \bookpart for each section all is well.

My trap was finding something that worked and using that as a template..

 

I have just  tried another old file and that too has failed, so possibly a
recent minor change somewhere in  Lily,Fresco,or Windows  has highlighted my
original sin.

There is no profit in trying to find the reason.

Problem associated with multiple quote sources

[Peter Gentry]

I have done some digging with small files.

1. putting each set of potential cues as reqd. as the first lines in each
music file (Movement) works  :

  cueNotesOneA=\include "file1.ily"

  \addQuote "cueNotesOneA" { \cueNotesOneA }

  Etc...

2. when several music files are instanced in an attempt to produce a single
score this fails

3. when this input is changed:   Move the list the cues  to  BEFORE each
\score {.} section it works 

4. However attempts to include a Header file (title dates text and .eps
picture) for the first page  and header text for each movement causes
failure but  when cues are defined.

5.  I use Book and BookPart sections to produce a score but just  using
bookpart sections also causes failure

6. I will try and reduce these complication header complications to isolate
the issue one step at a time.

Problem associated with multiple quote sources

[Peter Gentry]

Some time ago (2015) I prepared a quintet version of the Farrenc Nonetto. To
make things easier I added copious quotes to the many long chains of rests
to help the players. For this purpose I created an ily containing a set of
music for each line & movement (without cues) so that I could pick and chose
quotes to go virtually anywhere. This worked fine then but today it runs
into trouble.

 

\version "2.19.81"

%Preamble cut for brevity

 

% potential sources of cues for Movement One  ( bare indicates music without
any cues)

cueNotesOneA=\include "Op38_Alto_L2_M1_bare.ily"

\addQuote "cueNotesOneA" { \cueNotesOneA }

 

cueNotesOneB=\include "Op38_Clarinet_L3_M1_bare.ily"

\addQuote "cueNotesOneB" { \cueNotesOneB }

 

%similar data to above for other parts cut out for brevity

 

\relative c'' {

% Tempo and some notes etc cut out for brevity

 

es2 g2 )   |  % 6

as2 f2  |  % 7

g4 r4 r4 r4   |  % 8

% example of a cue

\new CueVoice \with { instrumentCueName="clt3" }

\cueDuring #"cueNotesOneB"  #UP {\set Score.skipBars = ##t s1*4/4*3 }  

 

% large chunkof notes  cut out for brevity

es'4\f r4 r4   |  % 413

c4 r4 r4   |  % 414 

 \bar "|."

} 

This works as expected for each movement on its own.

 

But when I combine the movements in a single file and include a frontpage
(in the usual way)  I get error messages such as

C:/Users/Peter/Lilypool/Music_Files/Farrenc/Op38_Alto_L2_M1.ily:7:1: error:
not a note name: cueNotesOneA

 

This also prevents the production of a complete score with all parts.

 

I realise the above is not a particularly small clip but it is the general
application of lots of quotes in a longish piece which is no longer working
as before.

The parts and score files are far too large to include here.

I have been pulling out the few remaining hairs if anyone knows why things
have changed since 2015 I would be very grateful

 

Regards Peter

 

RE: Frescobaldi Log Error -1073741819 on Windows10

[Peter Gentry]

Hello Andrew

 

I am sure my issue is neither Frescobaldi or Lilypond related. It is due to 
some alteration to the file permissions structure on the PCs which showed 
itself after a Windows update. It may or may not be due to the update. 

I managed to restore functionality on the laptop via a system restore. This has 
not been possible on the Desktop. I had been attempting to mess with 
permissions on that machine and this may have prevented the restore.

 

In any event I am sure the problems are not related to Lily/Fresco.

 

Thanks for all the valued suggestions.

Not sure if this is helpful at this stage, but with lilypond 2.19.82 and

Sometimes it helps to know all is working for somebody else. My result would

Are you installing all the W10 updates? There was one just this morning. I find

No, I'd say that's not at all too obvious.

In my experience, Windows systems are less stable when an update is awaiting
a restart to finish its install. I'd suggest doing a manual check for
updates and then a restart. Make sure it completely got over them. Apologies
if you've already done all that.

And, which version of Windows 10 is this? (Win-key + R, winver, Enter)

If it's not 1803, and your situation doesn't have a reason to avoid the
upgrade, I'd say get the upgrade. If something's gone sideways with Windows
internals, there's a chance the upgrade might set things right. 
(In fairness, there's ALSO a remote chance it could break other things...
Microsoft and their too-often Win10 upgrades... mumble mumble, rant
suppressed.)

I'd also wonder about hardware diagnostics. But since it sounds like this
problem suddenly came up on 2 different machines at once, a hardware problem
seems a lot less likely.

Yup 1803 fully up to date ; hardware diagnostics all pass. Still baffled.

I very much doubt it.

IINM the last thread on this was last April; perhaps start at 
http://lists.gnu.org/archive/html/lilypond-user/2018-04/msg5.html

Did this problem arise after you'd made some change to your systems?
Perhaps an upgrade somewhere? Maybe guile, ghostscript, …

Cheers,

No luck there David same log output after selecting verbose.  It must be 
somewhere much earlier. I tried "take access" of the .ly file but no joy

Previous post in the archive don't shed much light. Trying to check my own

Re: Frescobaldi Log Error -1073741819 on Windows10

[Peter Gentry]

I should add that I suspect this is a permissions problem not related to any
changes in Lilypond/Fresco as such. 

 

The first time it cropped up on the Desktop I closed some windows progs that
were running (I think it was outlook and possibly one other) and the error
no longer occurred.

 

Next time on Desktop it re-occurred and no other user apps were running -  I
switched to Laptop and no error.

 

Next day errors on both machines. 

 

I believe that there was a Windows update that downloaded on the Desktop (in
daily use) first and only subsequently on the Laptop.

 

Unrelated? I also find that an Outlook archive pst file saved on an external
drive is now inaccessible (no permission) ??

 

Is it too obvious to conclude that there was something in the last update
around permissions that is causing the issue.  I have Home versions so no
access to policies.

Exited with return code -1073741819.

 

I have no problems for some time and the above file used to compile without
error.

 

I think something similar has happened in the past but cannot remember the
solution - I have re-installed both  Lilypond and Frecobaldi.

 

There was the usual one time long pause on the laptop (?fonts) but in both
cases the error message promptly.

 

I will check through my archives and lily archives - does anyone have any
suggestions as to how to proceed to debug this issue?

 

Thanks

Re:Staff Group Spacing of five part score

[Peter Gentry]

Oh dear , what an idiot.  My troubles resolved by removing ragged bottom
true.

 

I'm not surprised no one responded. Its what comes from not understanding
all the overrides for spacings etc despite reading and re-reading the
manuals. Nothing wrong with the manuals.

Re:Staff Group Spacing of five part score (Peter Gentry)

[Peter Gentry]

The solution I came to was

 

By removing 

blank-after-score-page-penalty = #10

page-breaking = #ly:page-turn-breaking   

ragged-bottom = ##t

from the top level \paper block

 

and using

\bookpart{

  \score {

  \layout { #(layout-set-staff-size 25) }

   \new Score \with 

  {

   \override MultiMeasureRest #'staff-position = #0

   \override PaperColumn #'keep-inside-line = ##t

   \override NonMusicalPaperColumn #'keep-inside-line = ##t

  } 

<< 

   \new StaffGroup 

   <<

  \override StaffGroup.SystemStartBracket #'collapse-height = #1

  \override Score.SystemStartBar #'collapse-height = #1

 

 \new Staff = AStave

  <<

   \set Staff.instrumentName = "Flt1"

\set Staff.midiInstrument = "flute"

   \new Voice = "F1" {

\naturalizeMusic

 \include "Line1_M1.ly"

  \ledgers}

 >>

Etc  for all 5 instrument parts

 

 

 

This spaces two lines of the full score on each page as intended - but I
have no idea why?

Staff Group Spacing of five part score

[Peter Gentry]

I have searched the archive and found an entry which should work but when I
try it it doesn't. I must have misunderstood something along the line and it
may be about definitions.

 

I have a  group staff containing five parts. By default I get on one page
two "lines" of five staves. There is little space between the groups but a
lot of space below the second group. I am seeking to place these two more
evenly on the page.

 

My reading of the manuals led me to :-

Properties of the StaffGrouper grob

StaffGrouper properties are typically adjusted with an \override at the
StaffGroup level (or

equivalent).

staff-staff-spacing

The distance between consecutive staves within the current staff-group. The

staff-staff-spacing property of an individual staff's VerticalAxisGroup grob

can be overriden with different spacing settings for that staff.

staffgroup-staff-spacing

The distance between the last staff of the current staff-group and the staff
just

below it in the same system, even if one or more non-staff lines (such as
Lyrics)

exist between the two staves. Does not apply to the bottom staff of a
system. The

staff-staff-spacing property of an individual staff's VerticalAxisGroup grob

can be overriden with different spacing settings for that staff.

 

But

% First Score block

% ---

\score { 

 

\layout { #(layout-set-staff-size 25) }

  \new StaffGroup \with {   \override
StaffGrouper.staffgroup-staff-spacing.basic-distance = #10   } 

  <<  

 \new Staff = AStave

<<

   \set Staff.instrumentName = "Flt1"

   \new Voice = "F1" {\include "Line1_M1.ly" }

  >>

 

   \new Staff = BStave

   <<

   \set Staff.instrumentName = "Flt2" 

 \new Voice = "F2" {  \include "Line2_M1.ly" }

   >>



   \new Staff = CStave

   <<

   \set Staff.instrumentName = "Clt3A"

\new Voice = "C3" {\include "Line3A_M1.ly" \]

>>

 

   \new Staff = DStave

 <<

\set Staff.instrumentName = "Clt3B"

\new Voice = "C4" {\include "Line3B_M1.ly" }

 >>

 \new Staff = EStave

 <<

\set Staff.instrumentName = "Clt4"

\new Voice = "C5" {  \include "Line4_M1.ly" }

 >>

 >>

 

}  %end of score block

 

\header {  mycustomtext = \markup { \xSurname \xtitle " -" \xinstrument
} 

  piece =\markup {\fill-line {\column {
\center-column {   \fontsize #5 \bold \xmovI } } } }

 
}



 } % end of header 

} %end of bookpart block

 

 

However this must be incorrect since any value in   \override
StaffGrouper.staffgroup-staff-spacing.basic-distance = #n   has the same
result ie no effect.

RE: layout of markup text (Peter Gentry)

[Peter Gentry]

I have placed a copy of addTextSpannerText.ly to the C:/Program Files
(x86)/LilyPond/usr/share/lilypond/current/ly folder.

My score has five parts and in case a. each part/movement file includes the
statement -  \include "addTextSpannerText.ly"

Result -  Each part/movement compiles without error.

I also have a score file case b. which produces a full score of five parts
and currently two movements. Each part is input via \include "Line1_M1.ly"
etc within  \new staff blocks in a \bookpart block for each Movement.

With files as above b. fails with a cascade of  errors staring with

 C:/Program Files
(x86)/LilyPond/usr/share/lilypond/current/ly/addTextSpannerText.ly:3:1:
error: wrong type for argument 1.  Expecting music, found
"addTextSpannerText"

addTextSpannerText =

C:/Program Files
(x86)/LilyPond/usr/share/lilypond/current/ly/addTextSpannerText.ly:3:20:
error: syntax error, unexpected '='
addTextSpannerText 
   =
It looks as though in this case the compiler is treating each
"addTextSpannerText.ly" in the parts as music rather than scheme.

For b to succeed I remove all the   include "addTextSpannerText.ly"  from
the part files and put one statement at the head of the score file. 

But the corollary is that each individual part file will fail when compiled
alone. (I like to check each part/Mov before compiling the whole score.)

Is there a way to make the score file regard the part file \include
"addTextSpannerText.ly" statements as scheme as happens when the part is
compiled alone.

If this explanation seems convoluted it properly reflects my mind...:)

I was amazed at how complex this simple common problem turns out.

 

I have used the rather complex scheme code from the archives but there

I have had problems with Windows10 but lately all is OK.

Always go the official sites for Lilypond downloads after making sure your

This may/may not be relevant. The problem may be down to the way the

cannot remember how I resolved it. There seems to be some link to the
temporary file that using fresco can be cleared by closing all the files and
Fresco and starting again. Windows and Windows 10 can be a bit mysterious in

Re: Transpose range Apology

[Peter Gentry]

Apologies you must think me some kind of retarded idiot. I must learn to
think a bit before mistyping rubbish but at 76 these niceties seem a lost
cause.

 

Yes yes yes there is a problem with the tone tone semitone tone tone tone
semitone  notation and the octave note alteration calculation.

 

In my defence I hurriedly sent of a response to a question with some very
old code. At the time I did not solve the problem of computing a unique
number to represent the pitch.

 

The approximation in the code works because I was only interested in
modifying the octave component of the pitch.  The problem only has an impact
in the calculation of the range of an instrument and has never caused a
problem although I accept it could at the end points of each instrument
range.

 

So please don't be too hard on an old codger who just tried to help a fellow
dabbler out.

Well, I am glad that you don't sing in my hearing range then and you should

A semitone difference is quite noticeable.

A semi tone difference is indeed noticeable but surely there is no semitone 
between e sharp and f flat?
It’s the same key on the piano! Where is the semitone? 
Instead of enlightening me you simply reply with a superior and dismissive tone 
which is uncalled for.

RE: : Re: transpose range

[Peter Gentry]

You will need to modify the attach file (instrument_ranges.ly) since you are 
only interested in one instrument. 

 

A numeric pitch can be constructed from three components of the lilypond pitch p

 

1.  The octave o obtained from  (ly:pitch-octave p))  
2.  The note n obtained from (ly:pitch-notename p))  
3.  The semitone  a  obtained from the alteration  (* 4 
(ly:pitch-alteration p))  note alteration is in quarter tone steps

 

The numeric pitch (op) is calculated by (define op (+ (* 14 o) (* n 2) (/ a 
2)))  “op is a unique number representing the pitch of the note”

 

The procedure contains the instrument ranges as numeric pitches derived as 
above. 

 

See ;; clarinet range e to f#'  -1 2 0  to 2 3 0  (-10 to 35)

 

The current pitch is compared with the ranges and the octave 
increased/decreased as needed to bring the pitch into the range.

 

The note head and colour is modified to make all the changes visible on the 
score.

 

You can prune the procedure or add your instrument.

 

To call the procedure  

 

At top of the music file 

 

  \include "./instrument_ranges.ly"  (assumes the file is in the includes 
folder specified in Frescobaldi properties)

 

In a score block

 

\score {

  {

\naturalizeInstrumentRange "flute" {

\include "Boufill_Op8No3_Cc_M2_L1.ly" } }  (or sequential music)

  }

} % end of score block 

 

I hope this helps.

: Re: transpose range

[Peter Gentry]

Yes there is a way but it has disadvantages. 

 

Often the result is awkward jumps. I indicate changed notes by note head
style and colour so that it is easier to edit the results.

 

If you are still interested let me know and I will send you the scheme
procedure and an example. I allow for different instruments having different
ranges.

Re:Chords in LilyPond

[Peter Gentry]

Thanks to Carl and Kieren for explaining chord semantics.

 

A set of notes forming a chord  may have a different "meaning" depending on
the current key context.  Semantics seemed like a much grander idea to the
uninitiated.

 

However this idea would surely fall on stony ground in the context of atonal
or twelve note music.

Re:Chords in LilyPond

[Peter Gentry]

I have been intrigued by the highly technical correspondence on this topic.
However I have struggled to understand what is being discussed.

A bit of googling has shed some light
http://debussy.music.ubc.ca/muset/guido/section3.html for instance but other
sources are even more technical. I was particularly thrown by the term
"semantics" this is a slippery customer that seems to mean different things
in different contexts.

In the link above it is simply a recipe for how to populate various
properties or parameters if not explicitly defined.

ie  Semantics: 

*   If size or style are not specified when using \noteFormat, their
current settings remain unaffected. If not modified using \noteFormat, the
default settings are size=1.0, style="standard".
*   The specified parameters are applied to all notes within the range
of \noteFormat, or, if no range is specified, until (i) the next \noteFormat
tag changing that parameter or (ii) the end of the current voice.

Other links such as http://motools.sourceforge.net/chord_draft_1/chord.html
describe in some detail the structure of chords beyond the simple C G7 etc
descriptions including where a strong note outside the "normal" chord
members is employed often by a solo instrument.

All this is way outside by musical knowledge whilst interesting it is
difficult to understand.

 

Am I correct in seeing "semantics" in this way ?

This is not a serious issue(in the one instrument case)  as midi output at
best is only a good check of the harmonies or lack thereof.

Try as I may I cannot seem to provide a different midi instrument for the
two staves although the midi data components appear to be essential for a
successful layout .

 

The process will is good to input Basson music and display the equivalent
Bass Clarinet music but isn't much use when the aim is to produce music
transposed for a variety of instruments with midi output to quickly check
the entire score. This remains a multi step process.

in Adobe would 

 

a.  search all pdf files in a given directory
b.  search the entire contents of all the target files
c.  display the name of the pdf being searched as matches are found.

 

Now however the searches are confined to the index and the displayed name is

Re:tweaking clefs

[Peter Gentry]

Timothy Lanfear supplied a simple understandable way of achieving my aims.
I was thrown headlong down the route of trying to modify the sequential
music stream as was done for indicating/modifying pitches outside the
"range"  of each instrument. "range" being somewhat arbitrary as it  depends
on the skill of the musician. This employed range  data in the scheme
process and input instrumentname from the lily source  file

 

Appropriate clef and transposition can be easily provided entirely in Lily
data rather than fiddling about with the music stream.

 

The solution provided answers my immediate needs. Thank you very much all.

 

Ps   \inherit-acceptability is new to me I will have a search in the

tweaking Clefs

[Peter Gentry]

Is it possible to tweak clef properties in the same way that you can tweak
color and notehead style of a ly:pitch? Object.

 

Ie 

;rebuild the pitch and if a changed pitch add the color tweak

(if (ly:pitch? p)

  (let ((new-pitch (naturalize-instrument-range p instrument)))

  (ly:music-set-property! music 'pitch new-pitch)

  (if (and (not (equal? p new-pitch)) (color? my-color))

  (ly:music-set-property! music 'tweaks

  (acons  'color my-color

   (acons 'style 'harmonic-mixed

 (ly:music-property music 'tweaks)))

 

 

The clef properties I am trying to tweak are indicated by .data but items in
an 'elements structure are harder to get hold of.  Am I wasting my time
trying?

The reason for trying is that for a lot of the time I transpose various
quartets including bassoon, cello etc for a bass clarinet and or alto flute.

 

It would be nice to be able to change the clef at the same time as
transposing.

I often forget one or other and it is easier to input data in the original
clef for checking input.

 

Having started down this road it has become a challenge...Any help for a
ageing muso who has forgotten almost all the scheme/lily learnt last year
very gratefully received.

Re:Lilypond error behaviour

The errors that I frequently make show up as an additional empty stave or a

alerts me to an error but I have to search for it and they can be be very 
simple typos. Error messages in the log may also be a
later result of the error rather than pin pointing its location so some digging 
is usually required.
 
This seems fine to me as all you have to do is work through the input step by 
step to loacte the error. It would be difficult
(impossible) to pick out all input errors in programs like Lilypond compared to 
familar number crunching codes, how the heck does
the code know what your intentions are and what is an "error" in your source.
 
Lets not ask the impossible of hard pressed developers.

Spot on it was redundant. 

The main finding is that the sound produced for chords is not too good. I have 
tried a number of instruments and none of the sounds
are satisfactory. Maybe the sustained nature of the chords has some effect or 
is the attack part of the sound still shaped as a
concert piano. It is certainly different to the sound of the melody notes.

The melody notes sound pretty much guitar like but the chord sounds are 
more piano like they do vary when the instrument is changed but never 
sound anything like the melody notes.
There is a slight improvement playing the mid file through Soundfont 
which does give a bit better sound than the default player..

Just to be sure. You removed the \chordnames part and added the \chords.
When I did this I got a guitar (well, it didn't sound like a guitar, but 
it was not a piano) both for the melody and the chords.

I think it would be beneficial if you attached the .ly file so we can

RE: Fret Diagrams

[Peter Gentry]

 
Thank's Thomas that solves my problem..

I think I will have to change from a set of PDF manuals to the html version. I 
searched all the files for "Fret" and "N.C."
selecting the "any of the words option". This may have found the reference but 
could have been lost in a cascade of hits. 

Searching for \set noChordSymbol finds all the lines containing \set. It is a 
bit hit and miss searching for an answer much easier
to search when you know the answer. Search for noChordSymbol finds the answer.

Fret Diagrams

[Peter Gentry]

This may be trivial but searches of themanuals etc have not born fruit.

How do you prevent the markup N.C. appearing where there is a note rest. In 
fact  N.C. does not always appear sometimes once in a
bar sometimes twice for no immediately apparent reason.

If r1 is replaced by R1 then no "N.C." markup.

I have been trying out  http://do.remifa.so/archives/sheet_music/  no N.C. 
markup with \version "2.12.2" but with 2.19.25  "N.C."
appears where the chordname would be if there was a chord


I have included a small(ish) sample I have not used R1 in this but if you do 
then no "N.C."

\version "2.19.25"



\include "predefined-ukulele-fretboards.ly"

\storePredefinedDiagram #default-fret-table \chordmode {c:dim7}
#ukulele-tuning 
   "5-3;3-2;2-1;o;"

Re Position of rests in cue notes (Peter Gentry)

[Peter Gentry]

Brian Barker has supplied the solution.

That is replace say r8 by b8\rest in the set of cue notes - see   a8. (  [  g16 
]  r8 )  b8\rest  |  % 3 - I have left on r8 to
illustrate the problem.

It's a bit of a fag to change all the rest in the cueNotes files as I have (5 * 
4) 20 files one for each part and each movement.

\version "2.19.25"

cueNotes= \relative c' { 
 f8-. bes8-. (  d8-. bes8-. )   |  % 2
 a8. (  [  g16 ]  r8 )  b8\rest  |  % 3
 f8-. es'8-. (  c8-. a8-. )   |  % 4
 bes16 (  [  c32 bes32 ]  a32 [  bes32 c16 ]  d8 )  f8\mp (   |  % 5
 g8 )  es8 (  f8 )  d8 (   |  % 6
 es8 )  c8 (  d8 )  bes8 (   |  % 7
 a8\< )  a8\! r16 (  [  g16 f16 r16 )  ]   |  % 8
}
\addQuote "cueNotes" { \cueNotes }
\relative c' {
\set Score.midiInstrument = "flute"
\set Score.skipBars = ##t
 \set Score.markFormatter = #format-mark-box-alphabet
 \accidentalStyle "modern-voice-cautionary"
 \clef "treble"
 \key bes\major
 \numericTimeSignature
 \time 2/4
 \tempo "Andante con moto"4=69
 \new CueVoice \with {
   instrumentCueName="clt3"
  }
 \cueDuring #"cueNotes"  #UP 
 {\set Score.skipBars = ##t s1*6/8*4 }  
  d8\p r8  r8  d8  |  % 2
  es8 r8  r8  es8  |  % 3
  c8 r8  r8  c8  |  % 4

Position of rests in cue notes

[Peter Gentry]

I am using cuenotes in parts with extensive rests to give players reassurance 
with counting. 
The only issue is that rest are placed on the top leger line ie the F of treble 
clef. 
Is there a way to move these down to the midle leger line ie the B of the 
treble clef?

Merry Christmas to all Ponders...

While we are at it

Age 73 - Married - North of England

previous life Senior Scientific Oficer - Heat Transfer
Mechanical Engineering Degree
Struggling clarinet player and general music lover

Started producing music scores using NoteWorthy Composer

Graduated to LilyPond some years ago - still very much on the learning curve.

Like many others have had a fair amout of programming experience on IBM and ICL 
mainframes, PDP8 mini computers BBC Microcomputers
and the works of Master Gates. Minimal exposure to the likes of unix and linux

Lilypond is a godsend and a wonderful example of open source software with so 
many contributing and providing help and advice to
hapless strugglers. Bravo.

Should any other clarinet players want some baroque music to play feel free to 
raid  http://sunscales.co.uk not all of the files are
finished and I'm sure many contain errors.  They also reflect my modest 
progress with LilyPond. There aren't many ly files but just

One can also try to do this kind of iteration oneself in order to

  music))

 This works fine and I have used \displayMusic to show the 
music stream 
 to investigate other possible properties that can be 
specified in this way.

 I would like to specify note head style but this does not 
seem to appear as a property that can be applied in the acons list.
 In display music there is a complex list

This is an \override

 (make-music
 'ContextSpeccedMusic
 'contextt-type
 'Bottom
 'element
 (make-music
  'OverrideProperty
 'pop-first
 #t
 'grob-property-path
 (list (quote style))
 'grob-value
 'harmonic
 'symbol
 'NoteHead))

 Can this in any way be implimented by  the 'tweaks method.



How about:

\version 2.19.21

%% regard output of:
\displayMusic
{ \tweak style #'harmonic a'1 }

tweakI =
#(define-music-function (parser location music)(ly:music?)
  (ly:music-set-property! music 'tweaks
(acons 'style 'harmonic
  (acons 'color red
(ly:music-property music 'tweaks
  music)

{ \tweakI a'1 }

%% or:

tweakII =
#(define-music-function (parser location music)(ly:music?)
  #{
\tweak color #red
\tweak style #'harmonic
$music
  #})

{ \tweakII a'1 }


HTH,
  Harm

Thankyou very musch that works a treat. 

I couldn't find any specific information in the manuals and the displayMusic 
output  contains a lot more than simply 'style and
'harmonic.

As 2.19.22 is now available for download, let me smugly suggest:

\version 2.19.22
tweakIII =
#(define-music-function (music) (ly:music?)
  (tweak 'color red
(tweak 'style 'harmonic music)))

However, like all of the previous proposals, this relies on music
being a single tweakable item.  For noteheads, there is the 
more thorough style-note-heads function employed by 
\harmonicNote, so this part could be done by (harmonicNote 
music) instead (\harmonicNote uses a tweak for a single note 
and override/revert for everything else).

One can also try to do this kind of iteration oneself in order 
to only use the less invasive tweaks and get the color covered:

\version 2.19.22
tweakIV =
#(define-music-function (music) (ly:music?)
   (map-some-music
 (lambda (m)
   (and (music-is-of-type? 'note-event)
(tweak 'color red (tweak 'style 'harmonic m
 music))

If version 2.19.22 is not available, one can retain the 
parser/location arguments and replace the (tweak ...) line by 
the core of any of Harm's proposals.  map-some-music has been 
available since 2.16.0 at least, and all the rest for longer.

I haven't tested your code, but I like the idea of defining instrument-specific 
tonal ranges quite a lot!

Some ideas/proposals:

1)
Can you store the tone range for each instrument in an alist?

(define range-alist
  '((
   (clarinet . ( -10 . 34 ))
   (bass-clarinet-c . ( ...
)))

or even better, use pitches? You can extract upper and lower bounds from this 
alist and don't have to write a conditional check for
each instrument.

2)
IIUC, the line
(if (or (  op 34) ( op -10) ) (begin (set! o (+ o 1))) ))

adds one octave to the pitch if the note is lower than the lowest possible note 
OR higher than the highest possible note?
The latter doesn't seem quite right to me ;-)

(and ( op -10)
  (set! o (+ o 1)))
(and ( op 34)
  (set! o (- o 1)))

seems to do the trick (untested).

Apart from that, such a function is a valuable extension for lilypond IMHO.

Cheers,

Marc

Actually Marc I have revised and simplified the calculation (see attached)  - I 
simply wanted to indicate notes outside the range
modify then to fall inside the range. The colour then gives engraver/player the 
option to play within range or if that is awkward
play rests. I haven't sent to list before to save everyone the fag of looking 
at it again.

RE: Notehead color on programmed pitch change

[Peter Gentry]

Thankyou  David but how is color  associated with NoteHead? 
 
I hope these ramblings of a gnarled old scheme/Lily tyro can be of general 
interest
 
I'm guessing that 'tweaks is some sort of switch to open up properties of the 
current music object. 
 
In this case pitch is a property of  'NoteEvent and I'm guessing that color 
here is just NoteHead colour not NoteStem because
NoteStem is not within the NoteEvent including 'pitch.
 
NoteStem color may be available in a tweak of another music object or possibly 
supplied by another bit of code (engraver??). 
I do not know how code a tweak for stem color (apart from an override in the 
Lily .ly file) maybe you can't (anyway I don't want
to).
 
Also AFSIU ly:music-property extracts various elements of the current music 
item (possibly contained in  a deeper Lily code), and
allows user scheme to extract data from the current music object.
 
ly:music-set-property! does the reverse?
This part of my script kindly supplied by Thomas Morley

In line 3 a pitch is written to the music event it may be the old pitch or a 
new pitch.
In line 4 further action is taken if the pitch has been changed, first the 
variable my-color (previously defined) is type checked
In line 5 'tweaks is inserted into the current music object.

but how?
 
Cannot find a definition for acons but it must be a variant of cons 
(consists) it occurs 8 times in snippets and once in notation
and is clearly the way to tweak associating the Lily 'color with the user

Rather confusingly the format of color has many guises (x11-color 'red), (1 0 
0), simply 'red (no pun intended) and notehead colour
can also be approached via a grob. The notehead grob must be somehow implied in

We're simply creating a nested list:

 I'm guessing that 'tweaks is some sort of switch to open up 
properties 
 of the current music object.


You've seen
http://lilypond.org/doc/v2.18/Documentation/notation/the-tweak-command?
Any usage of \tweak in the ly file would appear in the 'tweaks 
list in the music representation.  Here, instead of using 
\tweak in the file, we're achieving the same result by 
modifying the music representation directly.

To see the music representation (basically what LilyPond does 
to your ly code to make it more digestible) wrap various music 
expressions in \displayMusic.  For example:

\displayMusic
{
  \tweak NoteHead.color #red
  c''4
}

Note how the tweak is represented.



 In this case pitch is a property of  'NoteEvent and I'm guessing 
 that color here is just NoteHead colour not NoteStem because 
NoteStem 
 is not within the NoteEvent including 'pitch.

 NoteStem color may be available in a tweak of another music 
object or 
 possibly supplied by another bit of code (engraver??).
 I do not know how code a tweak for stem color (apart from an 
 override in the Lily .ly file) maybe you can't (anyway I 
don't want to).


Well, you'd tweak Stem.  And once again, \displayMusic will 
show you what is done with your ly code:

 \displayMusic
{
  \tweak Stem.color #blue
  c''4
}



 Also AFSIU


don't know this one :)


 ly:music-property extracts various elements of the current music

 Thanks very much for your solution - I'm not yet sure why it

Well, most (every?) music-event may be tweaked.

Look at the terminal-output from:

\displayMusic
{
  \tweak color #red c''1
}

My code adds this tweak to the NoteEvent under certain conditions.

Well, perhaps you'll have success persuading outlook to keep 
your formating.
If not I'd look out for another mail-program ;)

I tried this

Further to this it seems the effect of this tweak is rather odd. The color of 
the following note head is changed but the note stem
is also thinner and this effect carries over to the next notes and indeed the 
number of notes affected varies see

\version 2.19.15

\displayMusic
\relative {
  c'4 c4 c4 c4
  \tweak color #red c''4 c4 c4 c4

The plot thickens.

I think you'll find that this is nothing to do with tweak: 
it's either the 
way your PDF viewer rasterises the stems where the notehead is 
above the 
stave, or an optical illusion.  Rasterising them at 1200 dpi 
and overlaying 
the stems in a image manipulating program showed them to be 
all identical.

Yes it is noting to do with tweak it arises from using the magnifier in the 
Frecobaldi output window - this can produce  apparent
variations in note stem width. They are  an artefact and do not affect the 
printed output. Case closed.

Notehead color on programmed pitch change

[Peter Gentry]

I have a short script to confine music to an instruments range. I wish to 
colour the noteheads on any pitches which have been
changed to fit the instrument range.
 
Try as I may all attempts to modify existing snippets have failed -  I was 
particulary baffled by the snippet 
 
#(define (pitch-to-color pitch)
(let ((color (assoc pitch colo-mapping pitch-equals?)))
(if color
(cdr color)))  
 
which in the abscence of a need for color-mapping  I couldn't replace with 
 
(color (x11-color 'red))
 
The above is not in the script as all attempts just failed - can anyone help 
please.

RE: Music function problem

[Peter Gentry]

 I have seen the error of my ways...

My previous use of a function needed just a music object this was simply the 
following music expression in my case an include file
of notes.

When the function has an additional parameter this must come after the music 
not immediately after the \functionname.

I was anticipating some internal Lily magic when the answer was simple...doh.

Thanks for putting me on the right track.

music-functions _do_ accept strings or numbers, something else

Well, you could just change the order of the parameters, viz:

callmyfunction =

Music function problem

[Peter Gentry]

I am trying to write an include file that will modify a music object dependent 
on the specified instrument.
 
I am trying to write a function that will call the current music object and a 
user supplied argument string/number with the object
of modifying the music object depending on the supplied number/string.
 
I can get this to work if the two arguments are ( ly:music? color?) but not if 
they are (ly:music? number?) or (ly:music? string?) 
 
The function call in an include file aimed to get a music object and a user 
number is 
 
callmyfunction =
#(define-music-function (parser location m n) (ly:music? number?)
(anotherfunction m n))
 
This is a fragment of the include file
 
In the lilypond file
...
\callmyfunction #2
etc

The define-music-function does not accept a number or string my puzzle is how 
do I get the music object and the user argument into
my include function. Any pointers gratefully recieved

I think I am missing something crucial about define-music-function
