I've just recently recorded another little drum video talking about the Matched Stick Grip. In this video I show you how to hold your sticks using the Matched Grip and how other drummers sometimes get this grip wrong.
Hopefully you'll find this video useful. It's always tricky when discussing a subject that the pupil has to physically feel to understand but if you follow the video closely you should have no problems in replicating the grip.
I've written another page discussing this subject just a little further here.
Get a Grip!
