How many rhythm patterns do you suppose there are? An infinite number, most likelyÌä but the core elements they are made up of are really just a few. The Elements of Rhythm, Vol. I, introduces a simple theory that explains and presents the origin of all the building block patterns. This includes all the basic 5 and 7 note polyrhythms, 6 note triplets, and 8th note jazz/Latin figures. Vol. I also offers a unique numbering system for categorizing the patterns. Everything youÌ¥ll ever play comes from here.
