Sibelius playback of triplets

I am trying to notate a basic 3 over 4 rhythm, but the playback feature is making me think I don't know what I am doing. Notation problems aside, is the following two measures, rhythmically enharmonic?

Basically, am I wrong to think that a triplet (or tuplet) can be subdivided by 16th's and 32nds?

Thank you!

Leaving aside your misprint - the tuplet number in your second bar should be a 4 of course - yes they're both OK.

In my example below, A, B and C are all acceptable. I prefer C. Some would say the modern trend is to favour A.

Yes, you can subdivide notes in a tuplet. And it can get even more complicated than D if you want, with tuplets inside tuplets. Today's 'modern classical' composers regularly come up with much worse than E!

Yes, those two measures are rhythmically equivalent. Reasonable cheat, eh?

Your second measure has a huge notation problem that obscures readability, though: that tuplet bracket is supposed to say 4 (for quadruplet) instead of 3 (for triplet). I think my brain automatically corrected it at first glance, so I didn't initially notice this egregious error until it was almost too late. This error is so bad that I'm surprised that the tuplet plays back properly. Did you purposefully change the 4 to a 3?

• Yeah, I know it was supposed to be a “4,” just goofed. You all knew what I was saying. Thanks for all the confirmations guys! Aug 11, 2019 at 11:09
• In the last year I have started taking my composing seriously, and inevitably you happen upon an idea that you cannot play, let alone notate. Aug 11, 2019 at 11:17
• @JasonHuff - Musescore notates the 4 properly by default, and I suspect so does Sibelius (and Finale). I really don't know how there's a 3 instead in your image. Aug 11, 2019 at 14:32
