Re: Canons

[Valentin Petzel]

Hello Stephan,

this can be done quite nicely:

\version "2.24.0"

partFine = {
  % Offset bar line to mitigate slightly wider stencil of |. barline
  \once\override Staff.BarLine.X-offset = #0.41
  \bar "||"
}

notesI = \relative c' {
  c1^\markup "1." c
  \partFine
}

notesII = \relative c' {
  e2^\markup "2." e e2. e4
  \partFine
}

notesIII = \relative c' {
  g'4^\markup "3." g16 g g g g4 g g g g g
  \fine
}

\score {
    <<
    \new Staff {
      \new Voice \notesI
      \addlyrics { \lyricmode { Hel -- lo, } }
    }
    \new Staff \with { \omit TimeSignature } {
      \new Voice \notesII
      \addlyrics { \lyricmode { hal -- li hal -- lo } }
    }
    \new Staff \with { \omit TimeSignature } {
      \new Voice \notesIII
      \addlyrics { \lyricmode { hel -- lo -- lo -- lo -- lo -- lo -- lo -- lo 
-- lo -- lo -- lo } }
    }
  >>
  \layout {
    \override Score.SystemStartBar.stencil = ##f
    % This allows us to have different Bars in each Staff.
    \enablePolymeter
  }
}

Cheers,
Valentin
