you move the stick so the tip hits the hats on the first 16th, and the shaft hits the edge of them on the next 16th.] it really should have a smooth, slick feel and sound, which seems to come from being really relaxed and fluid. also, a light touch overall seems to produce a nicer sound/vibe.
Sounds like the original Moeller tecnique as taught to Jim Chapin by S.A. Moeller. Except the tip strike is secondary. What you would actually be doing on the second strike is a pull out. Kenn Aronoff uses it,he also learned it from Jim.
Here it is in a triplet pattern.Throw down the first hit,at the time of the strike you arm should be parralell to the floor, then the wrist bends down to execute the second strike as the arm raises.
The real Moeller method is to hold the stick very loose,it should move in your hand,down ,tap,up.The up is a pull out. The tap should play itself.
For four notes you would play down,tap,tap up. Remember to let the stick move in your hand.
You can see an example on the Vic Firth website,cyber lessons with Dom Famularo,Moeller for the heavy hitter I think its called.Its with Dom and Jim.
