Re: Coloring Ledger Lines

[David B. Stocker]

I'm not sure what I'm looking at with the Scheme code, but I'll spend some time with it and see how it fits together.

Any clues as to how to fix the ugly spacing issue that results from using \stopStaff and \startStaff?

\version "2.18.2"

\paper {

indent = 0\in

ragged-right = ##f

}

\score {

\new Staff {

\relative c, {

\clef "treble_8"

\override Staff.NoteHead.color = #grey

\override Staff.Stem.color = #grey

\override Staff.LedgerLineSpanner.color = #grey

e4 f g a b

\stopStaff

\revert Staff.NoteHead.color

\revert Staff.Stem.color

\revert Staff.LedgerLineSpanner.color

\startStaff

c d e f g a b c

\override Staff.NoteHead.color = #grey

\override Staff.Stem.color = #grey

\override Staff.LedgerLineSpanner.color = #grey

d e f g \bar "||"

}

}

\layout {

\context {

\Staff \remove Time_signature_engraver

}

}

}

\score {

\new Staff {

\relative c, {

\clef "treble_8"

\cadenzaOn

\override Staff.NoteHead.color = #grey

\override Staff.Stem.color = #grey

\override Staff.LedgerLineSpanner.color = #grey

e4 f g a b

\stopStaff

\revert Staff.NoteHead.color

\revert Staff.Stem.color

\revert Staff.LedgerLineSpanner.color

\startStaff

c d e f g a b c

\override Staff.NoteHead.color = #grey

\override Staff.Stem.color = #grey

\override Staff.LedgerLineSpanner.color = #grey

d e f g \bar "||"

}

}

\layout {

\context {

\Staff \remove Time_signature_engraver

}

}

}

Interesting, thanks David.

Cheers,

To get more of the control any user would expect, you could do something like this:

\version "2.19.16"

\new Staff <<

  \repeat unfold 8 {

    \startStaff s4 \stopStaff

  }

  {

    a4

    \once \override Staff.LedgerLineSpanner.color = #blue

    a

    \once \override Staff.LedgerLineSpanner.color = #green

    a

    \once \override Staff.StaffSymbol.color = #red

    a

    a4 a a a

  }

>>

%%%%

I imagine this could be automated fairly easily.  Who knows the overhead with large scores, though!

(Aside: it might be interesting to come up with something emulating the old single-impression printing technique where staff lines, notes, and text were stamped together and inexactly aligned--http://en.wikipedia.org/wiki/History_of_music_publishing (under Rastell)  Can't come up with a good visual.)
