Re: Thaard's one year jazz-drumming study.
Jazz is like Chinese to me (a foreign language that I dont get and might never) but I did watch your video and the one thing that I kept waiting for you to change is your R hand grip when playing the ride. It just looks a little uncomfortable to me to have the hand open like that (palm up) and seems like you maybe use a little, tiny, miniscule, bit more energy when you play and have to turn it over to go to the hats or snare or anwhere else.
I am all for whatever grip works- dont get me wrong and I am nervous about even commenting here amongst the big dogs but I did notice it. Might just be that you only play the ride that way that seems odd to me.
Keep it up anyway. Sounds great and so relaxed.
