Benny Greb’s Alphabet
This is the rhythm alphabet, as created by German Drummer, Benny Greb. There are a billion exercises you can do with this. I, for example, am coming up with patterns of letters and playing the dots/rests to a metronome. This is an amazing exercise, and you can bring this onto bass drum patterns, ghost notes, hi-hat patterns, you can replace the rests with ghosts and the dots with accents. This will definitely improve your drumming.
