Here’s a polyrhythm of 9 over 6, or crotchet triplets in 3/4.

Try singing Someday My Prince Will Come whilst tapping the polyrhythm somehow.

Once you’ve got that, try playing the rhythms in the boxes.

The last line implies a 2/4, or 4/4 pulse. If you take this rhythm over three bars of 4/4, then…

Ah, wait…

I’ve wasted my life.

Actually, no. It’s not a waste. There have been MANY, MANY occasions when that has been useful.

Ummmm….

Nope.

Sorry :)
