12 years ago i discovered polyrhythm online via a steve vai article titled tempomental.

Example 5 features a two measure quarter note beat followed by the polyrhythmic groove from example 3.
This pattern represents a 2 against 3 polyrhythm but on a larger scale.
I just made a detailed and fast paced video on how this rhythm works and how we can practice it both ways by treating the 3 beat as dominant or the 4 beat as dominant.
Use y as the number of counts over which you ll play the polyrhythm before its various rhythms line up on the following count 1.

For example 3 evenly spaced beats against 2 4 against 3 and 5 against 3 are common polyrhythms but 4 against 2 is not because two divides four.

Again practice with the metronome and eventually reverse hands playing 4 in the right against 3 in.
