Re: breaking chords with \autochange

[Gilberto Agostinho]

Hi all,

I am so sorry, I pasted the wrong code in my first post... :-( Obviously the
function needs a second argument, and that's the correct code below:

\version "2.19.32"

autochord = #(define-music-function
     (parser location chordDown chordUp)
     (ly:music? ly:music?)
      #{
        <<
          {
            \oneVoice \change Staff = "down" $chordDown 
          }
          \\
          {
            \oneVoice \change Staff = "up" $chordUp 
          }
        >>
      #}
     )

\autochange {
  c c 
  \autochord   <d' f'>
  c 
  c'' c''
  \autochord   <d' f'>
  c''
}

Which outputs:

So basically what I am trying to do is to create a function that helps
breaking a chord down into two halves when using \autochange, since the
latter only considers the bottom note of a chord and place it in a single
staff (as opposed to breaking it down into two). This has been previously
discussed here:

Cheers,
