So, do you ever come across a triplet split 2:1, with a dotted note and a disconnected beam?
If I understood you correctly, I would argue most pieces in, for example, 6/8 are like this. Check out the opening to Chopin's 2nd ballade, for example.
These are, however, usually all played - each of the three notes, and I don't know if they're ever split into two, or just one of them played, etc., or how that might be notated. If that's not done, I guess a composer would have to switch to a compound time (6/8, 9/8, 12/8...) or use the approximation I talked about above, divide by 2, or 4, and then use the normal time values.
No, that's my point, these aren't triplets, as far as I'm aware. The 6/8 time allows two pulses or main beats, each with three eighth notes. That is compound time, providing three equal note values, where simple time only allows division by two. So, in the Chopin, the 2:1 ratio of note values can be scored with a quarter note and an eighth note. However, in simple time, one can force a note value to be split in three by using a triplet - scored using the normal time values but not played as such. So a quarter note's time might be given a triplet of three eighth notes with a beam, and a little "3" above. We know not to play them as eighths despite the use of those icons (because there aren't any others in the system for thirds of other values).These are, however, usually all played - each of the three notes, and I don't know if they're ever split into two, or just one of them played, etc., or how that might be notated.

Sure, you can do that. So in 4/4 time you might have a quarter note followed by an eighth note, and there would be a bracket over them with a "3" above the bracket. That would indicate that you were to divide that beat into three thirds, with two of the thirds taken up by the quarter note and one of the thirds by the half note. Hope that's somewhat clear.
Oh, right - thanks (also anacrusis for your confirmation of that).Any thoughts on my main point - assuming I've explained it well enough? Another way to think about it is, if you were going to play Happy Birthday to You with accompanying arpeggios in the left hand for some variety, making every beat a triplet (assuming it's in 3/4) would be perfectly natural (in fact, I saw at least one version where that's done), whereas a pattern of four notes would be awkward and sound machine-like. So, to my mind, those triplets are where the "Happy" should land, not a dotted eighth and a sixteenth. Maybe the whole question is pedantic, and the difference isn't actually that noticable, or it's understood that you play it rather more like a triplet. I'm just a bit taken aback that many pieces probably aren't notated how I think of them, because I've not really thought about how to notate them before. I've just counted these "sub-beats" as a matter of habit in all sorts of pieces. No doubt most of them are compound time - like an Irish jig will most likely be in 12/8 - and I happened to alight on these two examples that surprised me.
I may not quite be understanding your question, but....If you have an accompaniment in triplets and you have dotted notes in the melody there are two ways to handle it. During the Baroque period (and according to some, even as late as Schubert) the common practice was to fit the dotted notes to the triplets, so that if you had a triplet of eighths in the accompaniment and a dotted eighth and sixteenth in the melody, you'd play the melody so that the sixteenth lined up with the third triplet. That's because originally the dot just meant to lengthen the note a bit, not necessarily by exactly 50% of its value. So a Baroque dot could mean anything from a quarter and eighth under a "3" brace, to a standard dot, to a double dot, depending on the context and style of the piece. Nowadays, if you see such a thing, a triplet in the accompaniment against a dotted eighth and sixteenth in the melody, you are expected to play the 16th after the final triplet eighth, because we modern classical folks interpret a dot to mean a lengthening of the original note by exactly 50% of its value. But that was not always the case. So really you have to know how finnicky was the person who notated your version of Happy Birthday. ANd I guess it may be different in jazz.
