Re: For your edification: meters

[Anh Hai Trinh]

It looks really complicated. I think the diagram try to classify concepts that apply to different idea.

For example,

* simple(2/4, 3/8 etc.) vs. compound (6/8, 7/8 etc.) applies when talking about just the meter itself, i.e. one measure of music

* consistent vs. changing applies when talking about meters in one part or voice

* homogenous vs. polymetric, apply when talking about multiple voices or a piece of music
