Polyrhythms give this off-kilter, spiraling sensation that's pretty well unparralleled in the world of standard rhythms. You might imagine learning polyrhythms is essential for pianists, drummers or anyone who plays an instrument and sings (you'd be right) but it's also important for any modern musician, even those who play totally monophonic instruments. Why? Often enough, the music you're playing will call on you to create a polyrhythm with the prevailing groove. Feeling this properly is crucial to a flawless execution.
Plus performing a polyrhythm is a way to practice hearing, internalizing and expressing two (or more) concurrent non-derivative musical ideas: a core musical skill.
We cover 3:2 (triplets against eighths) in this video because it's the most common polyrhythm, but as additional practice, I made an extra practice track for 4:3 (sixteenths against triplets) since it's the next most common polyrhythm.
