Re: Leadsheet with cadenza / ad lib.

[Leo Correia de Verdier]

What is aligned in Lilypond is not the bars, but the lengths of the 
notes/skips/rests. CadenzaOn allows you to have a bar of arbitrary length, but 
does not negate the alignment of the note values (it’s also valid for all 
staves, as long as you haven’t moved engravers around). Your harmonies still 
need to have the same length as the melody, so:

harmonies = \chordmode {
  \global
  s16*19
  a1:m
  s16*22
  f1:m
  \fine
}
