Hi Jean,

Thanks for the quick response! I'm always happy to do something simpler,
but I admit that I'm a bit at a loss as to how to convert the linked
snippet to the construct you described. The snippet stores the \path for
the clef in a variable ("my-clef") and then sets is at the stencil for the
bass clef using a layout block like this:

\layout {
  \context {
\Score
\override Clef.stencil =
  #(lambda (grob)
 (let* ((sz (ly:grob-property grob 'font-size 0))
(mlt (magstep sz))
(glyph (ly:grob-property grob 'glyph-name)))
 (cond
  ((equal? glyph "clefs.F")
 (ly:stencil-scale my-clef (* 1 mlt) (* 1 mlt)))
  ((equal? glyph "clefs.F_change")
(ly:stencil-scale my-clef (* .8 mlt) (* .8 mlt)))
  (else (ly:clef::print grob)
  }
}

Where in that block would I indicate that kind of extra padding?

Thanks,
brin

Changing Clef horizontal-skylines

[brin solomon]

Hello,

I'm using a modified version of this LSR snippet
https://lsr.di.unimi.it/LSR/Item?id=900 to re-engrave a historical score
that uses a curly-style bass clef. The clef shape is a little wider than a
standard bass clef, and this means that it sometimes collides with notes
and rests when used in actual music. After looking at the internals manual,
I want to try adjusting the horizontal-skylines property, but I can't find
any documentation on what a "pair of skylines" should look like (as opposed
to a boolean, pair of numbers, etc). Can anyone point me in the right
direction so I can give this custom clef a little more space? Is there a
different approach that would be better here?

Many thanks for any thoughts!

Wow, this is really phenomenal! Thank you so much for this code! This

Hi Kieren,

Thanks for this example! This definitely feels close to what I'm looking
for, but I was hoping to find a way that didn't force a page break (or even
necessarily a line break) between scenes. Is that something that's
possible, or is the page break required?

Many thanks,
brin

Hi Kieren,

This is helpful, thanks! It seems I may have been overzealous in paring
down my minimal example: I actually am breaking the big score file down
into scenes/sub-scenes that can then be stitched together later in various
combinations. But I'm missing the step of how to get the header at the top
of the page to reflect what the current scene is at a given moment, since
evenHeaderMarkup and oddHeaderMarkup in the paper block don't seem to be
able to pull title/subtitle information from any except the top-level
\header block. So now I feel like I'm missing something that's right in
front of my face! Can you point me to the missing piece?

Many thanks,

Changing Header Mid-Score

[brin solomon]

Hello!

I am working on an opera and would like to use text in the header to help
the performers keep track of where they are in the score. So ideally, the
header on each page should say something like "Title of Opera: Act I, scene
ii", with the scene reflecting whatever the current scene is. Since there
aren't musical stops between the scenes, I would like the scenes to flow
into one another in the same \score block (so that a scene might start in
the middle of a line of music, say), which is pretty standard from the
opera scores and parts I'm used to.

Looking at the "Custom titles headers and footers" section of the 2.22.2
user manual, I can see how to create a custom header for the whole
document, but I can't figure out a way to pull information for the header
from specific moments in a \score block, or even how to pull information
for the header from a \score block when there are multiple \scores in a
given \book. Does anyone have any ideas on how to make this happen? I've
attached a minimal file that indicates the kind of headers I want over the
course of a few dummy pages. Any help would be greatly appreciated!

Thanks in advance,
brin
\version "2.22.2"

\header {
  dedication = \markup { \smallCaps "Title of Opera" }
}

\score {
  \new Staff {
c1^"Act I, scene i starts here" |
\repeat unfold 50 { c1 } | \pageBreak
c1^"Header on this page should read “Title of Opera: Act I, scene i”" |
\repeat unfold 50 { c } | \pageBreak
c \bar "||"
c^"Act I, scene ii starts here, header on this page should read “Title of Opera: Act I, scene ii”" |
\repeat unfold 50 { c } |

MIDI Output from Pitched and Unpitched Percussion on the Same Staff?

[brin solomon]

Hi all,

I'm engraving a percussion part that has the player switch from vibraphone
to suspended cymbal. I can use the \stopStaff and \startStaff commands to
change the number of staff lines and make the layout look like what I want,
but I'm having trouble with getting the MIDI output, since it seems that
unpitched percussion sounds are only available in the DrumStaff context. Is
there a way to switch from a Staff to a DrumStaff mid-score for the
purposes of MIDI output, or do I need to go in and write out two additional
percussion parts, one pitched and one unpitched, to use for the MIDI
version?

Many thanks,
brin

Hi Simon,

That's very close to what I need! The only time it doesn't work is when the
note doesn't wind up crossing a bar line: If I'm in 4/4 and write "c8*5" on
the downbeat, I get something that looks like an eighth note instead of a
half tied to an eighth. Is there a way to force that expansion, or should I
look into Abjad as Nathan suggested?

Non-Standard Rhythmic Durations

[Brin Solomon]

Hey all,

I'm working on an algorithmic piece where all the rhythmic durations are an
integer number of eighth notes long. I'm using Completion_heads_engraver to
handle the bar lines, but I'm running into trouble when I need to write
notes that are five eighth notes long. Is there a way to send an arbitrary
rhythmic value (i.e. one that can't be described with the 8, 4, 4., etc
system) to the Completion_heads_engraver, or do I need to enter all the
"half note plus an eighth" rhythmic values by hand without automatic note
splitting?

Many thanks,

Harm,

Thanks for finding this! Ideally it would be nice to not have the fermatas
over the rests, but if that's tricky to do, then this version is fine.

Hello Ben,

Maybe it's an issue with the screen shot, but it looks like there's no rest
in the lower staff in the screenshot? But it's interesting that the error
message disappears with the development version as opposed to the stable
one; any thoughts on what might have changed?

mmrest-of-length and \cadenzaOn

[Brin Solomon]

Hello all,

I'm trying to typeset a piece where one player has an unmetered cadenza
while every other player rests. I'm trying to use mmrest-of-length to
generate the rests, but if I use \cadenzaOn, I get the error "programming
error: Multi_measure_rest::get_rods (): I am not spanned!" and the rests
are not printed. This error doesn't happen if I use skip-of-rest instead,
but in that case, I don't get the rests.

Here is a minimal example that demonstrates the problem:

%%

\version "2.18.2"

MyCadenza = \relative c' {
  c4 d8 e f g g4
  f2 g4 g \bar "|"
}

\new GrandStaff <<
  \new Staff {
\cadenzaOn
\MyCadenza
\cadenzaOff c'1
  }
  \new Staff {
\cadenzaOn
#(mmrest-of-length MyCadenza)
\cadenzaOff
c'1
  }
>>

%%%

I'm running version 2.18.2 on Mac OS 10.11.6. Is there a different command
I should be using to get a full measure rest while I'm using \cadenzaOn?

Thanks in advance,
Brin
