Alright check this out: This is a basic Dennis Chambers Ostinato. He does something like this in his solo on the video with Tony Royster jr.
Step 1: count quarter notes on the hihat with your left foot. 1,2,3,4.....
Step 2: play the bass drum on 2 & 4 of the quarter notes. 1, boom, 3, boom, 1......
Step 3: play eighth note triplets with your left hand on the snare. 1 & a, 2 & a, 3 & a, 4 & a......
*Step 4: play a jazz ride pattern on your ride with your right hand. Here's the trick. Speed it up and slow it down while the rest of your limbs stay in time.
*Step 5 bonus: Keep the jazz ride pattern going in time with your right hand. Now use your left hand that is playing the eighth note triplets and speed it up and slow it down using a sixteenth note pattern. (Your left hand is playing singles. LLLL LLLL LLLL LLLL. 1 e & a, 2 e & a, 3 e & a, 4 e & a...... (switch back and forth between 8th note triplets and 16th note patterns.)
Have fun and enjoy.
