Trevor --
Thank you for your very clear explanation. I learned a lot from that.
I am nevertheless amazed that a performer would be able to keep track of
15/56ths of a whole note(!).

Well, isn't that a good argument for just leaving the whole thing alone?

That I really don't get. LilyPond is written in *English*. There is a
word "time" and there is another word "times"; they don't mean the same
thing, that's all. To write LilyPond code, we have to distinguish between
\override & \set,
Script & TextScript,
\addlyrics & \lyricsto,
(not to mention foo & bar).
People who speak a Romance language have to learn the difference between
\clef & \key.
And we have to write things like
#(override-auto-beam-setting '(end * * 5 8) 3 8)
and
\override Score.RehursalMarc #'brake-visibility =
#begin-of-align-invisibile
and
\acciaccatura { c16[ d] } e4 % 4 c's, not 2 or 3, no ch's or k's
correctly. But people are "confused" by \time vs. \times ?????
Hmmm. Well then, I'm confused about \with-color, \center-align, and
\lyricmode (I've never seen a "lyric"). Could we please get these changed
to \with-colour, \centre-align, and \lyricsmode?
