I am trying to code a piece with voices that use the same rhythmical
fragment over and over again. I would like to write something like:
\version 2.17.2
rhythm = { s8.[ s16] }
melody = \relative c { a d g f e b}
\score {
\new staff
\relative c { g2 d8 h e4 f }
\applyRhythm \rhythm \melody
\relative c { g2 d8 h e4 f }
\layout { }
}
It is annoying how many bugs you built into your skeleton. You should
really try to make them work except for the missing parts. At any rate,
it would appear that something like
\language deutsch
rhythm = { s8.[ s16] }
melody = \relative c { a d g f e b}
applyRhythm =
#(define-music-function (parser location rhythm melody)
(ly:music? ly:music?)
#{ $@(map
(lambda (p da) #{ $p $@da #})
(reverse!
(fold-some-music
(lambda (m) (ly:music-property m 'pitch #f))
(lambda (m l) (cons (ly:music-property m 'pitch) l))
'()
melody))
(apply circular-list
(reverse!
(fold-some-music
(lambda (m) (music-is-of-type? m 'skip-event))
(lambda (m l)
(cons (cons (ly:music-property m 'duration)
(ly:music-property m 'articulations))
l))
'()
rhythm
#})
\score {
\new Voice {
\relative c { g2 d8 h e4 f }
\applyRhythm \rhythm \melody
\relative c { g2 d8 h e4 f }
}
\layout { }
}
does the trick.

Now I suppose I should safe the snippet in a .ly-file and \include it into my code, right? If I do so and don't change anything else (meaning I don't actually _use_ the snippet yet) I get a whole set of errors when compiling. I attach them separately. Did I do something wrong or is it a problem with the snippet. I used the snippet for 2.16, using 2.17.2 for compiling. Any help is appreciated. An rtf file with the error log?

Hi, I am seriously sorry, I annoyed you with bugs in the code and lengthy files. It was not meant like that and I apologize. Especially since I really continue to be amazed by the efficiency of this list and the speed, with which help is offered. So I hope you will forgive my obviously mistaken approach. Nevertheless I got the help, that I needed - as always. Everything works fine with the file, that David posted. Thanks, again.

It's not as much a matter of annoyance than of efficiency. If people are willing to spend a few minutes on your problems, you don't want to have them spend this time on things that don't actually help you. With regard to the log file in rtf format: this is not going to be overly useful to most developers. So if you attach information to mail to the list, try avoiding a workflow involving Word or other word processors. Your mail client should be able to attach files without needing to involve a word processor. Nevertheless I got the help, that I needed - as always. Everything works fine with the file, that David posted. At some point of time, we probably should have a convenience function for the pattern (reverse!

It turns out that the ([extractor] m) pattern can be equally well done
separately using map!, so actually every function needed here is already
available, making this somewhat simpler:
\language deutsch
rhythm = { s8.[ s16] }
melody = \relative c { a d g f e b}
applyRhythm =
#(define-music-function (parser location rhythm melody)
(ly:music? ly:music?)

(map!
(lambda (m) (ly:music-property m 'pitch))
(extract-music melody
(lambda (m) (ly:music-property m 'pitch #f
(apply circular-list
(map!
(lambda (m) (cons (ly:music-property m 'duration)
(ly:music-property m 'articulations)))
(extract-typed-music rhythm 'skip-event
#})
\score {
\new Voice {
\relative c { g2 d8 h e4 f }

Oh to bad. When i send my message, i had no answers from anybody to the
initial message... Sorry
I answer to all messages at one time :
I get a whole set of errors
At the end of the snippet, there is a link here, to download the *last*
version of the snippet. Old versions don't work with Lilypond 2.16.
Well, i must admit that i didn't test \changePitch with 2.17
applyRhythm = #(define-music-function [...]
The code given by David is an example for all of conciseness, but has some
limitations
1- Doesn't work with chords
melody = \relative c { a d f g f e b} % error
2- All articulations in melody will be ignored
melody = \relative c { a\p d- g( f e) b} will gave the same
result than
melody = \relative c { a d g f e b}
3- You cannot have rests in the patterns
so you cannot have a pattern like :
rhythm = { c8 r8 r8. c16 }

Every code has limitations. The limitations of this example were
matched to the specs.
1- Doesn't work with chords
melody = \relative c { a d f g f e b} % error
2- All articulations in melody will be ignored
melody = \relative c { a\p d- g( f e) b} will gave the same
result than
melody = \relative c { a d g f e b}
3- You cannot have rests in the patterns
so you cannot have a pattern like :
rhythm = { c8 r8 r8. c16 }
Reality check: the given template used _spacer_ rests to specify the
rhythm. If I had copied the given melody into _spacer_ rests, the
output would not have been particularly impressive.
At any rate, a version with specs similar to what you now consider
missing has also been recently discussed and posted on the list IIRC.

Re: rhythm fragments in different pitches
Every code has limitations. Oh yes, of course. My message was just an information/advertisement for users looking for a rhythm pattern function. In a more general way, i really thank you, David, to post all these pieces of code, because it is very instructive for people trying to learn scheme. In your last code for example, i learn a util use of the circular-list that i could not imagine, and well, probably i will have to reconsider some pieces of my code ... -- Gilles ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
