Re: \times question

Hello David,

Thanks for the explanations!

I’ll become a super-smart new-fangled composer only next year probably, so I’ll go along your advice for the time being...

Hello folks,

The two tuplets below are visually different, but what’s the musical
difference, and how should a performer play that?

\version "2.19.55"

\relative c' {
 \times 2/4  {
   e4 f4 g4 a4
 }
 \times 1/4  {
   b4 c4 c4 b4
 }
}

That's just bad notation.  Either, by the way.  Factors of 2/4 and 1/4
do not make sense with \times.  They might with \scaleDurations (which
does not attach tuplet numbers) in polyrhythmical situations, but not
with a change in mid-sequence.

If you are a super-smart new-fangled composer and really really mean it,
you might want to consider explicit "2:4" and "1:4" tuplet numbers:
there is a special tuplet number formatter override for that (too lazy
to look it up right now).  Which is also helpful for distinguishing 7:4
and 7:8 (heptuplets of either persuasion can be found in scores).

In that manner, the notation becomes unambiguous again.  It doesn't
become a good idea by that, but at least one can see what is desired
from the executioner.
