How about using; \once \override NoteColumn.force-hshift = #1.0
Here is the code: \version "2.24.1" global = { \key c \major \time 6/8 } rightOne = \relative c'' { \global % Music follows here. e16 f f dis dis! e } rightTwo = \relative c'' { \global % Music follows here. d16 g, g \once \override NoteColumn.force-hshift = #1.0 d'! \once \override NoteColumn.force-hshift = #1.0 d! g, } \score { << \new Staff = "right" \with { midiInstrument = "acoustic grand" } << \rightOne \\ \rightTwo >> >> }
