Paradiddle Rudimental Drum Exercise

The best exercise in my opinion for beginners and intermediate players. Once you are comfortable with it you can increase the difficulty by increasing the tempo.

And also moving around the kit- snare, then tom1, tom2, floor tom and then back to the snare. When you do this I find it more convenient to start with the left hand- LRLL on the snare, RLRR on the tom 1 and so on.
