Re: Cadenza -- I'm missing something

In addition to Jean's explanation: Since I often have to create examples 
like the ones you provided, and LilyPond's treatment of accidentals in 
cadenzas split up into multiple "bars" started to annoy me too much, I 
switched to a solution not relying on \cadenzaOn: Instead, I'm using a 
function that automatically sets the measure length in order to hold the 
music given as an argument.

(The problem with \accidentalStyle forget being that while it works in 
your case, it leads to strange results in case the same pitch arises 
more than once in one bar.)

\version "2.22"

\layout {
  \omit Score.TimeSignature
  \omit Score.BarNumber
  indent = 0
}

oneBar =
#(define-music-function (mus) (ly:music?)
   #{
     \set Timing.measureLength = #(ly:music-length mus)
     \set Timing.measurePosition = #(ly:make-moment 0)
     #mus
   #})

tune = \relative c'' {
  \mark "C Dorian"
  \oneBar { c,1 d1 ees1 f1 g1 a1 bes1 c1 } \bar "||"
  \break
  \mark "A-flat Lydian"
  \oneBar { aes1 bes1 c1 d1 ees1 f1 g1 aes1 } \bar "||"
  \break
  \mark "G Phrygian"
  \oneBar { g,1 aes1 bes1 c1 d1 ees1 f1 g1 } \bar "||"
}

\score {
  <<
    \new Staff \tune
  >>
}
