The documentation for the \once prefix (both v2.14 and v2.15) at: http://lilypond.org/doc/v2.14/Documentation/learning/tweaking-methods says:
[...] effective only during the current musical moment before the property reverts back to its default value. It should say something like : "reverts back to its current value (this can be different from the default if an \override is in effect)." Slightly changing the example in the documentation illustrates this: c4 d \override NoteHead #'color = #red e4 f | \once \override NoteHead #'color = #green g4 a \revert NoteHead #'color b c | A single note is green, then we continue with red notes until we use \revert to get the default color (black). I think the learning manual can fully explain this without becoming overly complicated (this is the natural expectation from the English keyword \once). _______________________________________________ bug-lilypond mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-lilypond
