Polyrhythms 2:3 or 3:2

title pretty much asks it. But is a "2 against 3 polyrhythm" the same as a 3 against 2? or 5 against 7 same as 7 against 5? Seems like people use them interchangeably.

The way I see it, the second number usually coincides with the beats or subdivisions within the given time signature.

Of course, this isn't always the case but it is a good distinguishing point.

For example, 2:3 would be dotted quarters against straight quarters in a 3/4 measure, whereas 3:2 would be eighth triplets against quarters in a 4/4.

My two cents.

I do see what you're saying. Theoretically, you could look at a polyrhythm either way. It just depends which note duration you use as the "2" and which you use as the "3."

1) keep a beat, or (better yet) turn on a metronome.
2) tap eighth notes in your left hand, and triplets in your right. (2:3)
3) tap triplets in your left hand, and eighth notes in your right. (3:2)

any difference in the sound?

^Only if you accent one hand.

this is how Dusan Bogdanovic (classical guitar virtuoso, composer) suggests learning polyrhythmic passages when studying them. Feel each in the context of the other, and then be aware of both at the same time.

That's actually a good point.
