John,
This is a known issue. To compensate place a spacer grace in each of the other voices/staves. Mark From: lilypond-user [mailto:lilypond-user-bounces+carsonmark=ca.rr....@gnu.org] On Behalf Of John Burt Sent: Friday, July 24, 2020 11:31 AM To: lilypond-user <lilypond-user@gnu.org> Subject: Strange behavior with grace notes When the first notes of a piece are grace notes, if there are other voices, or other staves in the piece, the grace note is set in a separate bar, and then the time signature and key are printed again. I notice the same thing with appoggiatura and accacciatura. I tried to make this example as minimal as i could. \version "2.18.2" global = { \key f \minor \time 3/4 } tenorI = \relative c' { \global c2. } tenorII = \relative c' { \global \grace {c16 des16} c4 des8 des8 c8 } baritone = \relative c { \global \dynamicUp c2. } \score { \new ChoirStaff << \new Staff \with {\clef "treble_8" } << \new Voice = "tenorI" { \voiceOne \tenorI } \new Voice = "tenorII" { \voiceTwo \tenorII } >> \new Staff \with { } << \clef bass \new Voice = "baritone" { \voiceOne \baritone } >> >> \layout { } } if I comment out the tenorI voice and the baritone voice the grace note works fine. But if I uncomment either the problem returns. Any light anyone can cast on this would be much appreciated! John
