Thanks, Dominic, that helped for the given example, but I see that I need to give a more complete example of the chord chart I am working on. I also narrowed down the problem: the distance between Staff & ChordNames is not the same in the two lines, but I need it to be for this to work.
Luckily, between writing the first paragraph and this one, I managed to do just that. So below is the complete solution, and this problem is solved (I hope – until I find further problems): \version "2.20.0" << \new Staff { 1*4 1*4 } \new ChordNames \chordmode { \mark #1 a1 a a a \break \mark #1 \repeat volta 2 { a1 a a a } } >> \layout { \context { \ChordNames \consists "Bar_engraver" \override BarLine.bar-extent = #'(-2 . 2) \consists "Time_signature_engraver" \numericTimeSignature \override ChordName.Y-extent = ##f \override ChordName.Y-offset = -1 \override ChordName.X-offset = 0.5 \override VerticalAxisGroup.staff-affinity = ##f } \context { \Staff \hide BarLine \override Clef.stencil = #point-stencil \override StaffSymbol.line-count = 0 \remove "Time_signature_engraver" \override NoteColumn.X-offset = 0.5 \override VerticalAxisGroup.staff-staff-spacing.basic-distance = 3 } \context { \Voice \consists "Pitch_squash_engraver" \improvisationOn \stemUp fontSize = -4 } \context { \Score \remove "Bar_number_engraver" proportionalNotationDuration = #(ly:make-moment 1/8) \override SpacingSpanner.uniform-stretching = ##t \override SpacingSpanner.strict-note-spacing = ##t \override BarLine.space-alist.first-note = #'(fixed-space . 0) \override Clef.space-alist.first-note = #'(fixed-space . 0) \override Clef.space-alist.staff-bar = #'(extra-space . -2) \override Clef.space-alist.time-signature = #'(extra-space . -2) \override LeftEdge.space-alist.clef = #'(extra-space . 0) \override LeftEdge.space-alist.first-note = #'(fixed-space . 0) \override RehearsalMark.break-align-symbols = #'(left-edge) \override RehearsalMark.outside-staff-priority = ##f \override RehearsalMark.Y-offset = 0 \override RehearsalMark.extra-offset = #'(-4 . -4) } } \paper { indent = 0 left-margin = 2 \cm } -- Peter Crighton | Musician & Music Engraver based in Mainz, Germany http://www.petercrighton.de On Wed, 18 Mar 2020 at 04:54, Dominic <dominicirv...@gmail.com> wrote: > Hi Peter, > > I would suggest the following series of overrides to the > /Score.RehearsalMark/ object: > > /\override RehearsalMark.outside-staff-priority = ##f > \override RehearsalMark.Y-offset = #0 > \override RehearsalMark.extra-offset = #'(-2 . -0.5)/ > > This will effectively disable collision avoidance, set the marks on the > middle staff line, and then perform a final aesthetic adjustment as you > desire. > > Hope this helps! > > Dom > > > > > > -- > Sent from: http://lilypond.1069038.n5.nabble.com/User-f3.html > >
