Re: Creating two-staved ossia

[Pierre Perol-Schneider]

Hello Mr Ho,
Please don't forget to reply to the list.

Here's an attempt with v2.16.

Please note that I don't think this will help since v2.16 is pretty old and I'm almost sure no one one the list is using it anymore.

The best thing you have to do is to update your LP version (to 2.19.83 !!)

If you've found your LP version with the Ubuntu package, first uninstall LP. See how here: http://lilypond.org/unix.html

Otherwise, downloads are here: http://lilypond.org/download.html

Anyway, here's the attempt:

\version "2.16.0"

% See => http://lilypond.1069038.n5.nabble.com/magnifyStaff-and-key-signature-padding-td222389.html
staffSize = #(define-music-function (parser location new-size) (number?)
  #{
    \set fontSize = #new-size
    \override StaffSymbol #'staff-space = #(magstep new-size)
    \override StaffSymbol #'thickness = #(magstep new-size)
    \override KeySignature #'padding = #(* 2/3 (- 1 (magstep new-size)))
  #})

\header{
  title = ""
  subtitle = ""
}

upper = \relative c'' { % <= use \transpose c c'' for absolute mode
  \clef treble
  \key d \minor
  \time 4/4
  c1 c \break d d \break g g
}

lower =  \relative c {
  \clef bass
  \key d \minor
  \time 4/4
  a a bes bes c c
}

ossia = \new PianoStaff <<
    \new Staff \with {
      \RemoveEmptyStaves
      \override BarLine #'allow-span-bar = ##f
      \staffSize #-3
    } { \key d\minor s1*2 e''1 e'' }
    \new Staff \with {
      \RemoveEmptyStaves
       \staffSize #-3
    } { \clef F \key d\minor s1*2 f1 f }
>>

\score {
  \new StaffGroup \with {
    \override SpanBar #'glyph-name = "!" % <= won't work with v2.16
    \remove "System_start_delimiter_engraver"
  } <<
    \ossia
    \new PianoStaff \with { \override BarLine #'allow-span-bar = ##f } <<
      \new Staff = "upper" \upper
      \new Staff = "lower" \lower    
    >>
  >>
  \layout {
    \context {
      \PianoStaff
      \consists #Span_stem_engraver
    }
    \context {
      \Staff
      \override VerticalAxisGroup #'remove-first = ##t
    }
  }
  \midi {}
}

HTH, cheers,

Pierre

Hello Mr. Schneider,

I just cannot figure out how to implement the code you gave into my code because the format seems quite different and I am very new to music engraving.

This is the structure of my code and I want to insert an ossia like the one you showed in your example above a certain set of bars in the middle of the piece. Can you please help fuse the code you provided with mine because I am quite clueless now! Thank you so much for your time!
