Re: Change size of all notes in one voice with partCombine

[Dinh Hoang Tu]

Hello Jean and all,

I would love to contribute if I can :)

Using this in one music sheet, if 2nd voice has notes going upper and lower than 1st voice, \partCombine will not work.

\version "2.22.1"
localFontSize =
#(define-music-function (font-size music) (number? ly:music?)
   (for-some-music
     (lambda (m)
       (if (music-is-of-type? m 'rhythmic-event)
           (begin
             (set! (ly:music-property m 'tweaks)
                   (cons `(font-size . ,font-size)
                         (ly:music-property m 'tweaks)))
             #t)
           #f))
     music)
   music)
soprano = { f'4 g'4 a'4 b'4 c''2 }
alto = { d'4 e' \stemUp f'' g' a'2 }
basso = { d'4 e' \stemUp f'' g' a'2 }
tenor = { d'4 e' \stemUp \tweak font-size #-3 f'' g' a'2 }
\new Score { \new Staff << \partCombine \soprano \alto >> }
\new Score { \new Staff << \partCombine \soprano \localFontSize -3 \basso >> }
\new Score { \new Staff << \partCombine \soprano \tenor >> }

Many thanks again to any help.

Best,

Tu'

Hello Jean, Xavier,

I think these music functions are useful enough to be integrated into Lilypond itself.

I put them in my local music-functions-init.ly for personal use.

But it will be helpful for Lilypond users, including myself, to have these handy features by default.

Thank you and have a good day.

Hello,

Actually this particular music function is rather hacky. It only applies to notes and rests (not articulations or dynamics) and would fail with things like quoted music or events inserted via the edition engraver. In summary: it is not mature enough to be integrated in the core right away.

As described in my previous email, one of the projects on my stack would make \override just work as expected, so I would prioritize working on this.

Best regards,

Jean
