Re: Leadsheet with cadenza / ad lib.
Hi Leo
Hi Valentin
Thanks a lot for your quick replies.
Since my need is very local and limited, Leo's proposal works perfectly
fine for me.
Valentin, your extensive solution might be worth adding to the LSR, right?
Best regards
Stephan

Hello Stephan, hello Leo,
depending on the circumstances it might be useful to replace cadenzas with
scaled duration such that the music fits a whole measue. Using a small helper
function one might do something like this:
%
scaleMusicTo =
#(define-music-function (duration mus) (fraction? ly:music?)
(let* ((mdur (ly:music-length mus))
(mdur (/ (ly:moment-main-numerator mdur) (ly:moment-main-denominator
mdur)))
(tdur (/ (car duration) (cdr duration
(scaleDurations (/ tdur mdur) mus)))
melody = \relative c'' {
\global
\scaleMusicTo 1/1 {
\repeat unfold 19 { a16 }
}
R1\fermata
\scaleMusicTo 1/1 {
\repeat unfold 21 { f16 } f16\fermata
}
R1
\fine
}
%
The disadvantage of this is of course that Lilypond is going to treat these
note values as smaller note values than what is notated, which will affect
spacing. Alternatively you could define your cadenzas outside and automatically
have correct length rests and skips done:
%
cadenza =
#(define-music-function (n) (number?)
#{
\cadenzaOn
$(assoc-get n cadenzas)
\cadenzaOff
\bar "|"
#})
cadenzaD =
#(define-scheme-function (n) (number?)
(let* ((c (assoc-get n cadenzas))
(dur (ly:music-length c))
(dur (/ (ly:moment-main-numerator dur) (ly:moment-main-denominator
dur
dur))
cadenzaR =
#(define-music-function (n) (number?)
#{ R1*$(cadenzaD n) #})
cadenzaS =
#(define-music-function (n) (number?)
#{ s1*$(cadenzaD n) #})
cadenzas.1 = \repeat unfold 19 { a16 }
cadenzas.2 = { \repeat unfold 21 { f16 } f16\fermata }
melody = \relative c'' {
\global
\cadenza 1
R1\fermata
\cadenza 2
R1
\fine
}
harmonies = \chordmode {
\global
\cadenzaS 1
a1:m
\cadenzaS 2
f1:m
\fine
}
%
But note that this still causes bugs, because cadenzas do not play well with
multimeasure rests:
{
\cadenzaOn
c8
\cadenzaOff
\bar "|"
R1
}
This is because Lilypond does not handle cadenzas as an arbitrary length
measure, but simply stops timing. So instead of \cadenzaOn and \cadenzaOff you
could automatically use a suitable \partial:
%
cadenza =
#(define-music-function (n) (number?)
#{
\partial #(ly:make-duration 0 0 (cadenzaD n))
$(assoc-get n cadenzas)
#})
%

Re: Leadsheet with cadenza / ad lib.
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
}

Leadsheet with cadenza / ad lib.
Hi all
I have a song that starts with 1 bar of adlib (without accompaniment), 1
bar of silence in the melody, but with a chord, then another melody
adlib bar without accompaniment, and finally (in this example) again a
bar with chords only (w/o accompaniment). I cannot figure out how to
align the bars of the two parts (melody and chords, and further ones
later) properly. I tried to move the Timing_translator from the score to
the staff context but without success. Any advice is highly appreciated.
TIA, Stephan
BTW: the song is "Somethings' Got A Hold On Me" by Etta James - the
