Suppression des avertissements de chevauchement ¶

If notes from two voices with stems in the same direction are placed at the same position, and both voices have no shift or the same shift specified, the error message « warning: ignoring too many clashing note columns » appears when compiling the LilyPond file. This message can be suppressed by setting the ignore-collision property of the NoteColumn object to #t. Please note that this does not just suppress warnings but stops LilyPond trying to resolve collisions at all and so may have unintended results unless used with care.

ignore = \override NoteColumn.ignore-collision = ##t

\relative c' {
  \new Staff <<
    \new Voice { \ignore \stemDown f2 g }
    \new Voice { c2 \stemDown c, }
  >>
}
