Canons

[Stephan Schöll]

Hi all

I happened to typeset a few canons from several sources the last days. Let's assume we have a 3-voiced canon. I observed that they look somewhere between how one would set 3 parallel voices/staves and a single-voice tune running through 3 lines with a \break after every "line of lyrics".

Let's start with this MVE

\version "2.24.0"

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

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

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

}

\score {
    <<
    \new Staff {
      \new Voice \notesI
      \addlyrics { \lyricmode { Hel -- lo, } }
    }
    \new Staff {
      \new Voice \notesII
      \addlyrics { \lyricmode { hal -- li hal -- lo } }
    }
    \new Staff {
      \new Voice \notesIII
      \addlyrics { \lyricmode { hel -- lo -- lo -- lo -- lo -- lo -- lo -- lo -- lo -- lo -- lo } }
    }
  >>
}

    What I'd like to change (numbers refer to attached
    illustration):

* (1) remove "SpanBar" that connects the 3 staves on the left, so that it looks like having 3 systems

    * (2) remove fat barline at the end of line/staff 1 and 2, instead
    have a regular one \bar "|" (as if it would look like when having a
    1-voice melody (staff) going through 3 lines (systems)

* (3) remove time signature on line 2 and 3

    What I'd like to keep:

* (4) vertical alignment of the parts / lines

* (5) "fat" barline \bar "|." at the very end, after line 3

Or should I start with a 1-voice song (takes care of barlines and time signatures) and then address vertical alignment?

Any idea is appreciated! TIA
