Hello: More Scarlatti; In looking at this score what now jumps out at me is that this is really 3 voice polyphony forced onto two staves for the keyboard player. I don't know if that bit of information can be used to typeset this more efficiently or not.
The problem which now crops up is this: If the grace note is correctly placed and the octaves in the correct register I get "warning: ignoring too many clashing note columns" from the shell. This produces an c's in unison an octave apart because of to many columns. If I move the grace note to the other voice to correct, the problem is simply reversed. If I then add an octave correction to the C2 in bar 22 and make it c,2, its no better and the next bars are one octave to low. So it goes, no matter now I try to get this not collision to work, something else goes wrong. This is the offending bit of code: \include english.ly upper = \relative c'' { \clef treble \key e \major \time 3/4 e, b'' gs e b gs | % Bar 19 e8 b fs r4 r8 \bar "||" % Bar 20 \key e \minor r8 b''8 \grace a16 g8 fs e d | % Bar 21 \override Staff.NoteCollision #'merge-differently-dotted = ##t << { \grace b16 c2 \stemUp a'4 ~ | a8 a g fs b a | } \\ % bar 22 bar 23 { c2. \stemDown | b,2. } >> g'8 b \grace a16 g8 fs e d | % bar 24 \override Staff.NoteCollision #'merge-differently-dotted = ##t << { c2 a'4 ~ |a8 c b a d c | } { \grace b16 c2. | d2. | } % bar 25 bar 26 } lower = \relative c { \clef bass \key e \major \time 3/4 e4 r4 r4 | % Bar 19 r4 r8 e' b fs \bar "||" % Bar 20 \key e \minor e4 r4 r | % Bar 21 r8 a''8 fs8 ds c b | % Bar 22 b,,2. | % Bar 23 e4 r4 r | % Bar 24 r8 a''8 fs ds cs b | % bar 25 d,,2. | % bar 26 } \score { \new PianoStaff << \set PianoStaff.instrumentName = "Piano " \new Staff = "upper" \upper \new Staff = "lower" \lower >> \layout { } \midi { } } Thanks for any help, cheers, David -- David Fedoruk B.Mus.
