It was in response to your comment on 13/8 above. In the Leventikos 12/8, 12 = 3+2+2+3+2, the 3s have duplets metric accents. But it is hard to express that via meter. When notation, oen just sums it up. Bartok used (4+2+3)/8, that is 4+2+3 8 but on the Balkans one would just write 9/8 or 9/16. The beaming can indicate metric subaccents, but LilyPond cannot do that automatically, so I just skip it, >>> My example wasn't. >> >> Then one add another level on the musical line.

In irregular meters, the opposite happens: one looses the feeling for exact proportions. So one has to unlearn the idea of exact beats. If you want exact beats, then you need a sequencer track. I am not sure exactly what meter you want, but if the proportions are 3+3+3+3+1, then it will likely feel like a common 9 = 2+2+2+3 with a slight time bend shortening the last beat a bit, which is normally done. The tune Eleno Mome is often played in 7/8, but exists written as 13/16, 13 = 4+4+2+3, where the 3 has typical 2+1 patterns. In live performances, there might be something between 7/8 and 13/16. But exists written as 12/16, 12 = 3+4+2+3, and a performance plays it as 3+2+2+2+3. > Of course, if you adopt a pace where you can form that pattern > by grouping 26 rapid claps or whatever, then it can get simpler, > but I was talking in the context of straightforward note values > as sung by, say, a classical singer. On Balkans, they use 3s and 2s, counting on the fingers, for example 11 = 2+2+3+2+2. This way, smaller differences than be performed. But you might try using flute articulation t-k and t-k-t patterns. >>>> This Leventikos is also performed in 12 = 3+2+2+3+2, with quadruplets on >>>> the 3s - se my other post in this thread. >>> >>> OK, the quadruplets add another layer of complexity.

That's what makes it tripletty. So what are your intended metric accents? If the 1/3 at the end is subordinate to the i/4, then your meter will sound just like a 9/8 with a slight time bend, unless lsowed down to a zeibekiko. >>> At the bottom are the versions with undivided notes, with >>> the 1/12 notes represented in the only way I can think of. >>> >>> One interesting thing that popped out of my 3/8 notation is >>> that the odd quaver at the end of each bar can be linked to >>> the three quavers in the next bar.

We could eliminate a lot of tuplets and dots! As it is, beaming can indicate subaccent patterns. SO any such notation would have to think of that. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
