Garbled Lilypond Output

Question

I divided the notes of my score into 6 variables respectively called: \partOne, \partTwo, \partThree, \partFour, \partFive and \partSix. Each variable contains 20 measures of music. Then I call the variables in the score block. Whenever I call just one of the variables it works fine. If I call more than one, the output is completely messed up. Any ideas what’s going on?

---

Edit: responding to a few kind suggestions here.

1. I used the word “part” as it’s used in books and movies, not how it’s used in music, so I probably should have said “sections.” The point is they’re successive and not simultaneous.

2. I’m using hacklily.org web editor on an iPad because that’s all I have (no laptop or desktop).

3. Here is the full code I have so far:

This is what it looks like when I try calling more then one of the 6 variables:

Answer 1

Using the code from https://music.stackexchange.com/a/38118 this can be abbreviated to

\version "2.20.0"

\header {
  title = "Six Choose Four"
  composer = "Niall Mac Giolla Rua"
}

#(define (perm lst r)
  (if (zero? r) '(())
   (append-map
    (lambda (x)
     (append-map
      (lambda (old) (if (member x old) '() (list (cons x old))))
      (perm lst (1- r))))
    lst)))

showperm =
#(define-music-function (parser location r notes) (index? ly:music?)
  (make-sequential-music
   (map (lambda (x) (music-clone notes 'elements (ly:music-deep-copy x)))
        (perm (ly:music-property notes 'elements) r))))


\score {
  {
    \time 3/4
    \set beamExceptions = \beamExceptions { \repeat unfold 6 { 16[ 16] } }
    <<
      \showperm 4 { c'16 d' e' g' b' c'' }
      \repeat unfold 30 { \skip 2.*4 \break }
    >>
    \bar "|."
  }
}

\layout { short-indent = 0.0 indent = 0.0 }
\midi {}

and works fine in current LilyPond. Maybe the problem is with hacklily.org and/or the version of LilyPond it is running? There have been LilyPond versions that had problems with forced line breaks; this abbreviated input makes it easy to take out the forced breaks and see what happens.

Answer 2

I copied and pasted exactly what you entered in the question. I uncommented \partTwo and here's what it spat out. With this kind of inconsistency, it's probably best to find a different online LilyPond editor.

_{Addendum: hovering over some of the notes that were not included references lines that are outside the scope of your code. In other words: "Find this note on line 410!" There were only 200 lines in your code. Something, somewhere, is colliding. It's like it's accidentally mixing up your piece with some piece somewhere else. Accordingly, it wouldn't surprise me if buggy code is getting silently inserted unbeknownst to you.}

Answer 3

Anybody's guess without example code, but if you mix six parts via plain <<…>> into a single Voice context, "messed up" might describe the results pretty well since you get only one beaming, one stemming, one tie/fingering mechanism. Even tnough the noteheads will be at the right point of time but without proper collision avoidance.

Answer 4

If we stipulate that your other parts are similar to the first part (your example does not show the problem, so one has to fantasize about it), then it starts with an unqualified pitch c and ends with g a fifth above. If you put two of those parts in \relative, the second one will end up an octave higher than the first one.

The sanest solution is to put \relative c' in the definition of every "part" variable so that it won't bounce around in its octaves depending on what precedes it.
