Wrong choice of word, perhaps... I had been writing a lot of "\new Staff" and "\new Voice," and I (incorrectly) extended that pattern up to score level. It may be valid syntax, but I couldn't find what it's used for, anyway. > > - Do I just write a number here, or prepend '#' -- 1.0 or #1.0? > > Prepending works reliably almost anywhere, not prepending works in most > places except markup as well.

Like with _everything_ you use from Scheme inside of LilyPond. A-ha. OK, the trouble is that I don't really understand the boundaries between LilyPond and Scheme. I'm far enough along to see how music expressions fit together in voices and staves (more or less), but for overrides, I can copy and edit some commands from the manuals but I don't *really* know what they're made of at a deep level. It helps to know that # means "something from Scheme" and #t and #f are Scheme things, and so is 1.0, hence ##f and #1.0, but not ##1.0. Five years of intermittent use, and I didn't get it (maybe I still don't)... it may not be possible to improve, but it falls a bit short of being self-explanatory ;) In any case, clearer now, thanks for the explanation. hjh _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
