Re: Wildly different horizontal spacing in two similar scores.
I don't use that - I specify the exact number of systems I want, and on how
many pages, using:
\paper {
system-count = xx
page-count = yy
}
This forces the length to be stretched to the extent I require; then detailed
adjustments can be made with \break and \pageBreak.

Thanks for this, it works well, the only thing to watch is when you
specify too few systems the last one runs off the right hand side.

can someone point me to complete documentation for the partial command argument syntax?
I'm still baffled by it. After experimentation, I found this worked: \time 3/4 \partial 1 c4 | But "1"? 1 what? The pickup is a 2, and if I do this barcheck passes, as I expect: \time 3/4 c2 c4 | So from the doc examples I'd expect "\partial 2" to indicate a half/note pickup, but it fails. https://music.stackexchange.com/questions/106875/how-to-write-a-pickup-measure-with-5-16-duration-in-lilypond has some examples using the star operator, but I haven't found any ref for how to specify rationals. I don't really understand what's on the left and right of the "*", and I don't understand if the fractions are true fractions, or note fractions. Not sure what the right term for that, but in 3/4 time there are 3 1/4 notes in a whole bar, so the pickup in above is 2/3 of a bar, but is two 1/4 notes, or one 1/2 note (which takes 2/3 of the bar). I tried to use both approaches, no luck. These fails the bar check, an attempt at saying 2 quarter notes: \partial 2*1/4 c'4 | This is syntax failure: \partial 2/3 c'4 | wrong type for argument 1. Expecting duration, found (cons 2 3) I've searched for docs on the duration syntax, but I'm not succeeding yet. Can someone point me to docs, or perhaps explain the syntax? https://lilypond.org/doc/v2.21/Documentation/learning/advanced-rhythmic-commands#partial-measure as an example, just has a couple examples, but not a complete syntax. Thank you, Sam

Please don't just dump partial code that does not compile: this makes it impossible to accurately see what you are doing. You probably are using \partial wrong: its argument does not specify how long it is _since_ a full bar but how long it is _to_ a full bar. As such, you'd usually see ... \time 3/4 \partial 4 c4 | ... in typical contexts. -- David Kastrup

Thank you, that was definitely a problem, I hadn't understood that. For my more general understanding, is there documentation anywhere for the syntax of the argument to partial? Something that will explain the * syntax shown on this page? https://music.stackexchange.com/questions/106875/how-to-write-a-pickup-measure-with-5-16-duration-in-lilypond Thanks, Sam

The * syntax is described here: https://lilypond.org/doc/v2.22/Documentation/notation/writing-rhythms#scaling-durations The 16*5 means a duration of 1/16 multiplied by 5 which is 5/16, exactly what you wanted.

Should \partial accept music instead of duration?
Here would be a possible refactoring:
\version "2.22.0"
partial =
#(define-music-function (mus) (ly:music?)
(_i "Make a partial measure.")
(let* ((mom (ly:music-length mus))
(dur (make-duration-of-length mom)))
(make-music 'SequentialMusic
'elements
(list (context-spec-music
(make-music 'PartialSet
'origin (*location*)
'duration dur)
'Timing)
mus
\fixed c' {
\time 3/4
\partial { g8 a4 }
| g2. \bar "||"
\partial { \grace { g16 } a8 b }
| a2. \bar "||"
\partial \tuplet 3/2 { g8 fis }
| g2. \bar "|."
}
A convert-ly rule would probably not be possible given the limited power
of regular expressions. As such, \partial might need to support both
duration and music arguments. Initially I thought this might not be
possible, given that a naked duration can be treated as music; but the
following does seem to work:
\version "2.22.0"
#(define (duration-or-music? arg)
(or (ly:duration? arg) (ly:music? arg)))
partial =
#(define-music-function (arg) (duration-or-music?)
(_i "Make a partial measure.")
(if (ly:duration? arg)
(context-spec-music
(make-music 'PartialSet
'origin (*location*)
'duration arg)
'Timing)
(let* ((mom (ly:music-length arg))
(dur (make-duration-of-length mom)))
(make-music 'SequentialMusic
'elements
(list (context-spec-music
(make-music 'PartialSet
'origin (*location*)
'duration dur)
'Timing)
arg)
\fixed c' {
\time 3/4
\partial 4. g8 a4 %% Original syntax works.
| g2. \bar "||"
\partial { \grace { g16 } a8 b }
| a2. \bar "||"
\partial \tuplet 3/2 { g8 fis }

Hi Aaron,
I really like it! Always wondered why we need to specify a duration,
if it can be taken from the music.
I'd suggest to propose it on devel. Preferable the second coding,
because we could nicely deprecate the old syntax for some versions.
Thanks,
Harm

Fair point, though the intention here would be that backwards
compatibility would only need to exist for a time. A warning could be
issued whenever a user applies the older syntax; this would inform the
user of the impending breaking change while still allowing existing code
to compile. When it is convenient, a future release would only support
music as the argument.
