I first heard L. Shankar playing against a 9.5 beat tala, and the concept blew my mind. In western terms, it means that the relationship between the rythm and melody (plus any harmony if there is any) shifts 0.5 beats every cycle: for one cycle, the rythm may feel ahead, or on time, and for the next it may feel on time, or late. It's a fascinating technique that I think has no true analog in western music.

It is true that many forms of african-derived music in the US will shift the precise position of beats to create swing/syncopation/dilla-time, but this is generally done on a per-note basis, not on a per-cycle basis as happens with a half-beat tala.

Closest thing I could think of would be pieces like Piano Phase by Steve Reich.

Perhaps I am not conceptualizing this right, but it sounds to me like it is basically a hemiola, which can be found in a lot of western music, albeit not much in classical or pop. If you listen to math rock or stuff like meshuggah though, its all over the place.

Typically in music theory, we would talk about a hemiola as a rhythmic technique in which a rhythm in a simple (2) metric division is introduced in the context of a compound (3) division of the beat, or vice versa.

What the parent post describes isn't an isolated gesture like that, but a sustained state of overlapping meters, if I'm understanding correctly. In the case of the ICM described, as well as math rock/meshuggah/etc, I would describe the technique as "Polymetric" or maybe a "Sustained polyrhythm," and not a hemiola.

Gotcha, so does share structure with some niche western music but hemiola is kot quite the right term for it.
