Re: Notation: Piano: How best to indicate left hand or right hand fingering in polyphonic works?

[R.H.]

Dear Pierre

Indeed, very helpful. 

I also chieved coloring of notes, stems, etc. I did not want to color lines, clef... but it works similar to what you suggest, but the solution you proposed I did not know. Any suggestion allows me to learn more and more about LP.

I will post my solution soon based on all input so far as it has a specific purpose.

Thank you

Roland

Let us assume you want the top or bass voice to be in another color. Here, the way you created it seems to make this difficult to do, for example to assign a different color to note heads of different voices -- independently of left or right hand fingering.

See: http://lsr.di.unimi.it/LSR/Item?id=443

Ex.:

\version "2.20.0"

#(define (override-color-for-all-grobs color)
  (lambda (context)
   (let loop ((x all-grob-descriptions))
    (if (not (null? x))
     (let ((grob-name (caar x)))
      (ly:context-pushpop-property context grob-name 'color color)
      (loop (cdr x)))))))

sop = { c''8 8 8 8 8 8 8 8 }
alt = { c'8 8 8 8 8 8 \change Staff = LH \stemUp 8 8  }
bas = { \clef F c8 8 8 8 8 }

\new PianoStaff <<
  \new Staff = RH <<
    \new Voice { \voiceOne \sop }
    \new Voice
      \with { \applyContext #(override-color-for-all-grobs (x11-color 'red)) }  
      { \voiceTwo \alt }
  >>
  \new Staff = LH \bas

HTH, cheers,
