EDS Lesson Two Introducing eighth notes
A single stroke roll comes from the fact that you play a single stroke per hand, so that the hand pattern will be as shown below in Exercise 1 (for right handed drummers).
Play a bar of quarter notes and a bar of eighth notes, round and round on the snare drum (or practice pad).
Count out loud as shown in Example 1 above, read the ‘+’ sign as ‘+and’, so you will say “1-2-3-4-1-and-2-and-3-and-4-and”.
