Re: Staff change in piano music - a general approach?

[Phil Holmes]

Strictly, the ignore-collision override doesn't just suppress warnings - it 
stops LilyPond trying to avoid them.  Shane has given you one option for 
avoiding the double flag in your final note.  An alternative would be to use 
\once \override Stem #'length = #n to adjust the stem lengths.  Another 
option would be to typeset the final alto note as voiceTwo, to make its stem 
face downwards.

As Shane has said, I'm not sure there's a general solution, because what you 
want isn't something that's generally done - effectively to make chords out 
of different voices.

Yes, you perfectly understood me. But using chords is totally impractical 
for me as I already have the individual voices as LilyPond code.

I tried as you described below and I'm getting a little closer. However, 
there are still some problems, one of which you can see in the attached 
example: the final chord consisting of two eighth notes actually looks like 
a sixteenth note chord.

\override NoteColumn #'ignore-collision = ##t
is just to suppress the collision warnings, right?

Tobias


% example

\version "2.12.3"

global = {
\clef treble
\time 2/2
\key g \dorian
}

soprano = \relative c''' {
\voiceOne
g4 g d4. e8 |
}

alto = \relative c'' {
\voiceOne
b4 c b4. c8 |
}

tenor = \relative c'' {
\voiceTwo
g4 g g2 |
}

\score {
\new Staff <<
\global
\override NoteColumn #'ignore-collision = ##t
\new Voice { \soprano }
\new Voice { \alto }
\new Voice { \tenor }

}
