: Effective way to notate triplets I was directed by America Luke to this forum site. I hope this is the correct place. I have a score with a lot of triplets. It's awkward to write always times 2/3 {c16 d e} times 2/3 {d

A better looking grouping:
relative c' {
override TupletBracket.bracket-visibility = #'if-no-beam
times 2/3 { c16 c set stemRightBeamCount = #1 c }
times 2/3 { set stemLeftBeamCount = #1 c c c }
}

yields this:

You have to specify the property tupletSpannerDuration to get several tuplets using only one times command:

set tupletSpannerDuration = #(ly:make-moment 1 8)
times 2/3 {c16 d e d e f }

See LilyPond Documentation for more on this.

It's worth pointing out that as of LilyPond 2.17.11, you can write

tuplet 3/2 8 {c16 d e d e f}

and get 3:2 tuplets in groups of duration 8 (in this case, two groups of three tuplets each). This is basically the same as temporarily overriding tupletSpannerDuration.

I think that your problem isn't intrinsically with the triplets, but rather with controlling beams; one approach is to manually set the beams:

Running lilypond 2.16 on

{
times 2/3 {c16^"Two 3-note phrases" d e } times 2/3 { d e f } r4 r2

times 2/3 { c16^"Manual Beaming" [d e] d [e f] } r4 r2

set tupletSpannerDuration = #(ly:make-moment 1 8)
times 2/3 { c16^"Moment & Manual Beaming" [d e] d [e f] } r4 r2

}

yields this

The square brackets in the lilypond file indicate the beams in the same manner as parentheses indicate slurs.

I think, there is no need to restrict the contents of one brace to 3 notes only, so for consecutive triplets, as in your example, a minor compression can be:

times 2/3 {c16 d e d e f}
