My last hastily-slapped together piece on 4:3 metric modulation was such a hit with my Drummerworld.com poeple, that I thought I should backfill some preparatory exercises for it. Here the emphasis is on keeping the hi-hat on 2 and 4 in the original tempo- you should also try them putting it on the 2 and 4 in the implied time, as in the previous pdf. In addition to some very basic and explanatory examples, I've given some practice phrases in 3/4 and 4/4, and some ways of filling out the time Elvin Jones-style, with a couple of bonus "hot licks".
I haven't been exactly systematic with either of these pieces- when and if I hammer this into a complete and coherent presentation it will be going into a book or magazine submission- but I'm a big advocate of incomplete information anyway. You learn better this way.
