Re: [talk] easy tuplets

[Janek Warchoł]

Hi all,

First thing that i'd like to say about Graham's proposal is that
supporting arbitrary integer durations doesn't mean we have to abolish
\times (or \tuplet, if we decide to rename it).

I imagine that we could have arbitrary integer durations intended for
use with straightforward tuplets, while continue using explicit \times
command for complicated (for example nested) ones.

LilyPond doesn't know about any tuplet beaming rules, but i think
Graham meant general music notation tuplet rules.  Like the ones that
can be found in Elaine Gould's "Behind Bars".

And by the way, look at the output of this:

{
  \times 2/3 { b8 }
  \times 2/3 { b8 }
  \times 2/3 { b8 }
  \times 2/3 { b8 }
  \times 2/3 { b8 }
  \times 2/3 { b8 }
  r2
}

Interesting - i mean, TupletNumbers are all wrong, but the beaming is correct.

As for dividing tuplets here

\times 2/3 { c8 c c c c c c c c c c c
             c8 c c c c c c c c c c c }

we can use tupletSpannerDuration.  We could have it calculated from
time signature or something like that.

what's the difference?

Interesting.  Apart from which one would produce tuplet brackets,
maybe *x/y notation would allow us to distinguish between

  \times 2/3 { b16 b b }
  \times 2/3 { b16 b b }

and

  \times 4/6 { b16 b b b b b }

by writing { b16*2/3 b b b b b } and { b16*4/6 b b b b b }, respectively?

b12 is still more brief, though.

As for \times 2/3 {c8. c16}, {c12. c24} seems clear enough from my
perspective.  No idea whether "computers will like it", though :)

cheers,
