I'm telling you this is a good system. It gives you the thing, some basic variations on it, starting on 1 or 2, straight and syncopated, and it makes you do it for as long as you should do it. Basically that's what you should do with every single identifiable idea you play on the drum set.
This is the inverse of what I posted last week— we're playing a jazz time feel, with the bass drum playing the major TC accents, filling in the remaining notes of an inverted quarter note triplet on the snare drum. And there is an accompanying Reed-type method to develop all of this further.
It's fun doing the standard left hand moves with these pages, playing a rim click on the snare drum— gives a nice Elvin-like texture.
