(ly-get-mus-property mus 'elements) returns a possibly non-empty list
of music objects.
(ly-get-mus-property mus 'element) returns () or a music object.
You should always recurse on both, since constructs like \context
Voice layer another Music object over their arguments.
If so, why do they return () for every call to
ly-get-mus-property? Can I evaluate nested sequences like nested
lists? Is there a better way to do all this?
Repeats happen in interpreting, i.e. after \apply is done, so what you
want can not be done. Better write two functions
(apply-duration-to-note mus dur)
and
(apply-durations-to-sequence muslist durlist)
use these to write a function that is called like
\apply #(lambda (x) (apply-durations-to-sequence
(ly-get-mus-property x 'elements) (list
(make-duration 2 1) ;; dotted quarter
(make-duration 3 0) ;; eighth
))
The apply-durations-to-sequence should loop through its 2nd argument
for setting durations. When you go this route, be sure to be careful
with nesting other music in the { } .
Btw, if you finish the code, could we include it in the examples?

Lilypond crashes while compiling this (correct) file...
Hi all, I have a file, which would not compile thou the end, but only until a certain point. It crashes during the LaTeX portion: Running LaTeX... error: latex: command exited with value 256 Traceback (most recent call last): File /usr/local/bin/ly2dvi, line 863, in ? run_latex (files, outbase, extra_init) File /usr/local/bin/ly2dvi, line 639, in run_latex system (cmd) File /usr/local/bin/ly2dvi, line 247, in system error (msg) File /usr/local/bin/ly2dvi, line 145, in error raise _ (Exiting ... ) Exiting ...

I attach the file, which is outcommented from line 72 on. It would fail after l 72 c 54 if not excommented. The problem is that this part is part of a score for larger orchestra, and I have to deliver it this week... I would really appreciate any help - if you know the problem...

I want to suggest the use of placeholders to make the \notes easier to
read and maintain.
a b b c d d e *8. *16 *8 * * * * becomes
a8. b16 b8 b c d d e
If you are willing to move your notes out of the .ly file,
which is a very good idea, this
can easily be processed with sed.
# this plugin routine replaces gub gub re* * with regub gub
# skip ** if two and write one * fter this procedure.
s/\*\*/TwoAsterisksWriteOne/g
:again
/\*/{
s/\([^ ]*\)[^\*]*\*/\1/

Here is an example of an .ly file with a separate score:
% here we have flowing2.ly:
\header {
title = The river is flowing
composer = Traditonal (?)
}
\include paper16.ly
\score {
\simultaneous {
% accompaniment--chordnames
\context ChordNames \chords {
\include flowing2-pt1.ly }
\addlyrics
% melody \context Staff = mel {
\property Staff.noAutoBeaming = ##t
\property Staff.automaticMelismata = ##t
\notes \relative c' { \include flowing2-pt2.ly }
}
% lyrics
\context Lyrics \lyrics { \include flowing2-pt3.ly }
}
\midi { }
\paper { linewidth = 10.0\cm }
}
% and here we have flowing2, the notes. If you copy this into two
% files and run ./petals flowing2, running ly2dvi on either the
% original flowing.ly (by Han-Wen, in the tutorial) or
% flowing2.ly will produce the same score. The score should start with
r8,
% not this comment.

Of course it's not petals anymore, that
name is taken by rosegarden. ly-parts?
I just finished a simple song 64 bars
long. Each line in the editor is a measure
but you can find the measure by the
lyrics. Of course I could have put all the
lyrics on one line, but that wouldn't
be a very good idea, would it? Also
lilypond has no problem finding the
line number in the score part, which is
the same as the line number in your score.
It would be easy to put half a measure or two
measures on each line instead. Barchecks could
be used for a particular part by doing a matrix
transposition of the part, putting it all on a
single line. I have never found them useful.
Finding errors is very easy,
Re: Tempo signature
Are there commands to produce, e.g., Allegro, Adagio, Largo at wanted
positions?

Marco
If you want to write these indications above the staff with a
good-looking separation from it, you can use the following command:
--
\score {
\notes \relative c'' {
% Move textscripts two steps left and three steps up.
\property Staff.TextScript
\override #'extra-offset = #'(-2 . 3)
c4^#'((Large upright) Allegro)
% Restore defaults
\property Staff.TextScript \revert #'extra-offset
d e f
...
}
}
--
The trick is in '(-2 . 3)': the first number gives the horizontal offset,
the second the vertical one.

Re: Pairing/Combining Two Sequences Together
Take a look at the example file input/test/music-box.ly
in the distribution. I think it does more or less what
you're trying to achieve.
/Mats
Does anyone know how to perform an operation (using the Guile
interpreter) that combines two sequences of notes? I'm not entirely
sure how to iterate from note to note, and I'm not sure how to get at
the notes after they have been evaluated for unfolding repeats.
I wanted to pair two sequences of music together so that I could avoid
redundant durations.
This:
---
music = \notes \context Voice \relative c' { c d e f g a b c }
myduration = \notes \repeat unfold 4 { s4. s8 }
\apply #combine-dur { \music \myduration }
---
Should result in about the same thing as this:
---
\notes \context Voice \relative c' { c4. d8 e4. f8 g4. a8 b4. c8 }
---
Just to test things, I defined the function 'combine-dur' like this:
---
#(define (combine-dur x)
(display \n===\n)
(let ((a (ly-get-mus-property x 'elements)))
(display (car a))
(display \n===\n)
(display (cadr a))
)
x)
---
I noticed by looking at what displayed that (car a) was the
\myduration sequence and (cadr a) was \music. However, the two
resulting sequences do not act like ordinary lists, and normal mapping
functions do not work. In addition, (car a) is the unevaluated form
of \myduration, with information about how many times to repeat but the
repeats themselves not unfolded.
At this point I'm at a total loss. Are (car a) and (cadr a) both
valid types of music? If so, why do they return () for every call to
ly-get-mus-property? Can I evaluate nested sequences like nested
lists? Is there a better way to do all this?
I spent a few hours looking through the documentation, and I searched
a while on the mailing list archives, and I couldn't find a similar
question. The music-reversal example was informative, but it doesn't
deal with sequences inside of sequences and post-unfold-evaluation.

Justified staffs
Hello all, I needed two things that I didnt find in the manual 1) how can I control breaks (I didnt get it with \bar ... it just does not break when there is space... and I couldnt user \penalty ... I tried #0 value and #9) 2) how do I justify a staff (I want staffs of the same length and the notes distributed over them) 3) I'm writing unmetered music and I want not the time signature to appear, how do I do it? (I have already written \cadenzaOn and set the property Score.timing = ##f but the 'c' still appears at the start of the score) TIA! -- Felipe Massia Pereira http://www.ic.unicamp.br/~ra000493 CS MSc Student @ IC-UNICAMP ___ Lilypond-user mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/lilypond-user
