The basic orchestration:
Using this rhythm from Syncopation as an example:
Play the melody rhythm on the cymbals, with the bass drum in unison:
Fill in the gaps in the rhythm on the snare drum:
Play the hihat (with your foot) in unison with the snare drum:
You could instead play a simple rhythm with the hihat, or leave it out altogether; putting it in unison with the snare drum just duplicates the kind of coordination used in 4-Way Coordination.
The actual practice drill:
Do the above orchestration using sticking patterns from the beginning of Stick Control— or from my page of Stone-type patterns. For example:
This is entire area is secondary-level conditioning, after you've developed a basic drumming vocabulary. But keep this in mind if you're working on Dahlgren & Fine— there may be better ways of developing the same thing. How useful this method will be depends on your level of fluency with 4WC. It may be better at first to read the exercises the way they are diagrammed in the original book; at some point it will become useful to switch to my approach.
