New issue 2164 by [email protected]: Learning Manual: Better explanation
with updated example for \once tweak
http://code.google.com/p/lilypond/issues/detail?id=2164
Submitted by

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).
