We really need a plain simple way to set a fixed channel. There is
enough hardware around using dedicated channels.

In LilyPond there is no such thing as "transpose down 4 half-tones".
You transpose from one key to another, not by a distance.

\transpose cis' a will remove 4 sharps, take -4 steps on the circle of
fifths. If you'd rather add 8 steps on the circle of fifths (the
difference implying that the circle isn't actually a closed circle), you
need to write something like \transpose des' a instead.

You need to use the correct syntax for slurs in the first place. Both (
and ) come right after the note they connect to, and the reason for that
is exactly because it makes it easy to make properly connected adjacent
slurs.
You should not ignore syntax warnings LilyPond gives you: they indicate
a problem with your source file.

\keepWithTag alto ...

But one would need to look at the rest to see whether this kind of tag

Kind of stupid, but Scheme syntax is very simplistic (almost anything
except for parentheses needs to be space-separated) and your problem
here is that # goes into Scheme.
So you call upon one Scheme variable endtone} which does not exist. Put
a space before the closing brace.

Have you ever seen any of those?
At the same point of time, a lot more needs to be done for an extra clef
than setting the Y-offset . In terms of implementation, it would be
possible to split much of the work into a neutral "SubStaff" and context
mod, like doing
\new SubStaff \with \ExtraClef #-3 "violin"
but this still does not deal with reseating the current Voice to the
SubStaff and back afterwards, necessary for keeping beams and slurs
operative. So there would need to be separate commands for that.
So instead of a targeted end-user feature limited to clefs, we are
talking about some fuzzy generic framework requiring an expert to cater
for the particular common use case.
There is something to be said for a more generic name/feature such as
SubStaff in terms of the context hierarchy, moving the necessary fixed
mods into a context mod.

If made built-in, it would affect several files and introduce a new

I don't think it covers multiple simultanous main clefs (like sometimes

sensible common interface including this use case.

in \tempo 4 = 80 , the 4 is not a number but a duration. This works
when writing
myTempoBase = ##{ 4 #}
myTempo = 80
global = {
\key c \major
\time 4/4
\tempo \myTempoBase = \myTempo
}
because ##{ 4 #} resolves to a duration rather than a number.

Supporting GM2 would mean fast-forwarding all the way into the distant year 1999 (for GM2 v1.2a, even to 2007). I actually use MIDI devices regularly that don't do GM2. MIDI 2.0, in contrast, is from 2020. It would be overoptimistic to expect the average established musician to work with devices developed as recent as that. And it's not unreasonable to assume that many of those interested in using the kind of workflow LilyPond offers would pass as "old-school" and have a leaning towards old-school devices, regardless of what biological age their ID might pronounce. So in my book, offering support for GM2 _and_ other instrument/patch schemes beyond GM1 would be more of a priority over going MIDI 2.0. -- David Kastrup

Of course it doesn't work to change the dotcount when the chord as such

Any idea how to get is fixed in this particular case? Calling git grep "override[^=]*#'[a-z]" in the current Frescobaldi source tree delivers _way_ too many hits.

I can't figure out your function details, but assuming you have
sequential music mus that should (in \relative) follow relative rules
but only have the first note affect the sequence, you would wrap it in
(make-relative (mus) (make-music 'EventChord mus)
...)
This works by casting the expression to an EventChord before running it
through the \relative wringer (in case this occurs in \relative) but
making the permanent effect on \relative come from the first element.
The ... itself is never seen by \relative, only the EventChord is. The
result can, of course, end up something that isn't a valid chord but it
is only used for passing through \relative and then thrown away.

You are thinking too complicated.

up = \drummode {
\slurDown \grace {sn16 sn(} 4
}
\score {
\new DrumStaff

\score {

Booth on Chemnitzer Linuxtage 2024
Hi, if you think you'd like to help providing a booth on the Chemnitzer Linuxtage 2024 (happening on the weekend March 16/17), please checkout the CfP at <https://chemnitzer.linux-tage.de/2024/en/programm/anmeldung/live>. Note that companies but not community projects are charged for booths. We'd need 2–4 persons manning the booth and prepare suitable presentation material, and help people with questions and showcase working on music and performance material. If we have suitable people and can figure out a suitable goal, we could think about offering a workshop. I am not sure we'd get a talk slot since I just held a LilyPond talk this year. I'd probably try to land a Shotcut video editor talk (I've not yet talked about key frames in Shotcut which allow to the "smooth scrolling" stuff in videos like <https://youtu.be/spAP7ODPCyg>). Particularly if I get that talk in, it would be good to have at least two more people for the booth. There is a yearly bus organized from the Ruhr area if that helps. The conference is the largest in Germany with a similar theme (typically about 2500 to 3000 visitors). Interest? The conference is a friendly meeting place, and presenters get a nice social event on Saturday with catering. -- David Kastrup

It was probably easy to overlook, but my reply did contain the requested
functionality. The output was not exactly pretty in most other regards.
I was both answering the question as well as making a point about the
example code.
Sometimes I don't answer questions at all because I am not in the mood
to write a complete example myself for the sake of someone else. In
this case, I decided to just go with what was given and in that manner
show that a better prepared question would have made for a better
recognizable answer.
The actual recipient of the answer did get the solution. It just
appears that I confused other readers.
Sorry for that.

Yes, there is really no comparison. Emacs has better MIDI recognition than Frescobaldi, and editing Scheme-only files is nicer. And it blows the socks off anything as a viewer for Lilypond's Info documentation. I use Emacs for editing LilyPond because I am used to working with Emacs for everything.

MIDI settings can be changed globally (or in a book or bookpart), but
the generation of an actual MIDI file is only triggered when a \midi
block is encountered inside of a \score .
Something like that. It doesn't help the user as much when you tell
them what doesn't create a MIDI file: after all, they will rather be
looking at how to create one.

Could you live with the following?

\key c\major
\once\override Score.BreakAlignment.break-align-orders =
#(grob-transformer 'break-align-orders

It tells LilyPond to end the line formatted in a way as if it continued

I think it is more likely due to vibrato having become a tenet of string sound (partly because it hides the fundamental problem of intonation) and frets considerably reduce the amount and change the character of vibrato (I know that you can bend the pitches of the sitar a whole lot, but the character of its frets is quite different). Viols were used much more polyphonically than modern bowed strings, so vibrato wasn't really an option and the frets improved intonation more than they deteriorated it. For plucked/hammered/struck strings, the mathematical time/frequency unsharpness relation makes the intonation stand out less because of the tone decay (for example, few people notice that pizzicato strings sound higher than when they are bowed). -- David Kastrup

Probably this should just be "strings" which it typically associated with the kind of instruments listed there and has the advantage that you don't get into trouble for a) pizzicato (which is weird for "bowed strings") or b) viol (which is both bowed and fretted and may be used in a string section for nostalgically informed practice). -- David Kastrup

Ah, you are right. What musicxml2ly doesn't do, however, is inserting
any \partial. So the rhythm does not go bonkers because there isn't a
partial measure to start with.
I am not able to properly judge this from the MusicXML: how does this
appear to Finale? In particular, where does measure 1 start? With the
"partial" measure or the first full measure?

Well, musicxml2ly converts the rhythmic structure just fine. Headers and footers look somewhat messy, and there is an extraordinary amount of power chords (essentially, everything that isn't a seventh chord) that I consider suspect. I think Frescobaldi has its own MusicXML converter: if that is what you have been using, you should file a problem report with Frescobaldi rather than LilyPond. -- David Kastrup

Or Finale didn't, and musicxml2ly made a mistake. In which case this

My bank actually refuses cashing foreign country checks these days, so
I cannot avail myself of this particular offer. While I like the
prospect of a simple recurring source of income, I think it would be
more desirable in the long run to make sure that pickup measures travel
with some reliability from Finale into LilyPond.
So it would be good to take a look at the involved MusicXML.

I suspect you write something like
{ \time 3/4 c'4 \partial 4 ...
when you would need to write
{ \time 3/4 \partial 4 c'4 ...
Namely, you need to write \partial 4 _before_ the partial measure, not
after it.

Tuplet brackets too short?
If I write
\new Staff
{ \time 2/4
<< \tuplet 3/2 { c''4 d'' c'' } \\ \tuplet 3/2 { g'4 a'2 } >>
}
the results look awful:
Shouldn't both tuplet brackets span every notecolumn within the purview
of the last note's duration? I think this might also apply if the upper
voice contained 4 eighths instead of the three triplets:

The problem is that I don't know where to locate the bug. The
difference appears to be that \voices creates a \context Staff wrapper
around the parallel construct. I suspect that the idea is to help with
continuing voices, like if you compare the outputs of
{ << { \voiceOne e'2~ \oneVoice } \new Voice { \voiceTwo c'2 } >> e'2 }
{ \voices "",2 << { \voiceOne e'2~ \oneVoice } \\ c'2 >> e'2 }
The second clearly looks more sensible, but if you look closely, there
still isn't a tie, so the voice does not actually continue in this
situation. So this situation still is not helped in any manner, and the
one thing \voices has over unadorned << \\ >> is that it takes named
contexts.
Clearly this discrepancy is worth removing; I just don't know right now
why it exists in the first place. I must have been thinking something.™
Now independent from the two constructs differing by a \context Staff
wrapper (added in voicify-music in scm/music-functions.scm).
What is additionally puzzling is that either change is accomplished by
voicify-music, so why is one use affected and the other not? Or does
this happen when voicify-music is applied multiple times (the second
time during scorification)?
All this appears mostly unrelated to \tuplet tripping over one but not
the other incantation.

Frankly, I must have completely misinterpreted your request. It sounded
to me like you were talking about drum-style notes. A OneStaff context
is for putting several contexts which usually would have their own lines
("vertical axis") into one.
Maybe you want to show a hand-drawn sketch of what you want because at
least I have no idea what we are talking about at this point of time.

You can just use \skip \music but you have to forego rhythmic alignment

Check out

\version "2.25.7"
notes = { \repeat unfold 12 c'4 }
words = \lyricmode {
\skip 1*2 % Lyrics to start at bar 3.
one4 two three four
}
{ << \new Voice = "cantor" \notes
\new Lyrics \with { associatedVoice = "cantor" } { \words }
>>
}
% ~~
Note that the associatedVoice may seem irrelevant when the timing isn't
derived from it, but it is required for a few things like proper
placement of syllable extenders.
Also note how the syllable "one" gets an explicit length of a quarter.
In real music, you'll get a lot more note lengths in the lyrics.
This will look uglier in the source, but it tends to be quite more
robust against music edits not affecting the syllable positions. And of
course, skips become quite easier to accommodate.

Have you tried not "anything like to-barline" but rather _exactly_

Post Scriptum: of course in this case, the relevant interpretation (in terms of whether one lands before court) would be that of Artifex as the Ghostscript copyright holder. I don't think that they'd go to court over LilyPond using a separately distributed Ghostscript that is not just usable by LilyPond. The other way round we are talking about LilyPond copyright holders going to court because of Ghostscript being called by LilyPond. This would only make sense for copyright holders before the time that Ghostscript became a fixture for graphics processing and TeX was used instead, so we are talking about copyright holders from LilyPond version 1.x and earlier. At that time, however, LilyPond was licensed under GPLv2+. It just doesn't come together as something that I can see as a viable threat scenario. -- David Kastrup

And it is sort of fuzzier: after all, dynamic libraries are also some kind of boundary. The principal differentiation is whether that boundary is artificial and the separate parts operate as a single unseparable unit. Ghostscript works with PostScript as a generic interface, it has lots of other uses, and LilyPond can work without using Ghostscript (it can produce PostScript files instead). I think that puts enough of a conceptual barrier between the two. Using the Ghostscript API would be different: I'd expect distributions to avoid that without explicit non-trivial user action. > Of course, whether MacPorts's automated determination of > distributability can capture this distinction, is another question. -- David Kastrup

\new Staff = "staff" {

Maybe you are not clear about what the name behind alignAboveContext
signifies? You need to have a VerticalAxis carrying context at the same

If you want to go the extra mile, you'd only print ♮ in key cancellation messages grobs and would precede them with the _previous_ number of sharps/flats. So switching from E major to B♭ major would print 4♮2♭. You would not get 0♮ however (not as a main signature, not as a cancellation signature). This may or may not be what the OP wants.

A quick `git grep lilymidi` confirms that there is is no documentation for lilymidi. Zero, zilch, nada. It is installed with other binaries and is used by elisp/lilypond-song.el (but what for?).

What is apparent is that it may be a bad idea to first pause a number of
bars and only then include \global with a different \tempo .
But the location of the tempo change aside your principal problem, like
before, seems to be that timidity as a player skips initial rests.
Try fluidsynth -ia pulseaudio -n on your MIDI file as an alternative (on
my system, I get inexplicable problems with -ia pipewire or -ia alsa)
instead.

It is a consequence of syntax compatibility to previously when
\alternative could follow a \repeat rather than be inside of its body.
So the last music before an in-\repeat \alternative must not be a
\repeat without \alternative or it will sweep up the \alternative for
itself. As you noticed, braces are the proper workaround.

Well, \note-by-number #1 #0 #UP is essentially the same as \note {2} #UP
If you are not calculating note values, \note tends to have the simpler
syntax.

Uh, there isn't even \note in there?
The problem in the above is a quoting problem: you mustn't quote
#{...#}, and you can avoid quoting it using quasiquote and unquote:
\version "2.25.7"
#(define foo `((96 . ,#{ \markup { \note-by-number #1 #0 #UP }#})))
{ c'1^\markup {#(cdr (assoc 96 foo))} }

Good example why it is a bad idea to use non-standard input formatting
for aesthetic reasons: you lose a proper idea about what you are
actually doing. Both ( and ) are post-events following a note and can
have a direction prescribed using _ and ^ (ok, it is only heeded for the
opening brace).
So you can just write:
\version "2.22.2"
\relative c'' {
4_(
bes16)( a c bes d c ees d)

Yes, and yes.

My mistake: Dynamic_performer by default lives at Voice level, so you'd
need \new Voice here in order to issue the dynamics on a level visible
to MIDI.

Try
\new Staff << \MyMusic \MyDynamics >>
since otherwise the variables will end up in separate Staff contexts.

The only actual difference to LilyPond is that if you call lilypond somefilename and somefilename does not exist, somefilename.ly will be tried instead. So .ily is not more than a convention. Enough so that editors and other utilities making decisions (like syntax highlighting) based on the file name will tend to know what to do with .ily. -- David Kastrup

"Iteration" is the main processing pass of music in musical time order. There are several processing stages for music: out of my head: Entry, scorification, iteration (several different internal phases for that as well), page breaking and output. Iteration is done separately for typesetting and MIDI and of course page breaking is just done for typesetting. -- David Kastrup

I have no idea what you tried, but the below works as expected for me.

\key e \minor
\time 6/8
}
melody = \relative c' {

\tuplet 3/2 8 { e16 g e g e g a e a b d b c g c b g b} |
}
\score {
<<
\new Staff \melody
\new Staff \with {
beamExceptions = \beamExceptions { \tuplet 3/2 {
16 [ 16 16 ] 16 [ 16 16 ] 16 [ 16 16 ] 16 [ 16 16 ] 16 [ 16 16 ] 16 [ 16 16 ] } } }
