Weckl explains how, in his evolution DVD, he turned his traditional style, into a rebound technique, and his left was doing something that in all my years of playing traditional, has been a nono.
Letting the sick free, opening the hand. And it is true.
He explains that if you keep the index finger in top of the stick, it is limited in how much up it can go, or how much rebound you can get, without the need to actually twist your arm, in order to achieve max speed and rebound,.
In his own words, its ok to open the hand, actually, the fingers stay in the stick for low volume control of the stick, but for power and speed, he completely opens the hand.
Its the pendulum principle, where a continuous movement keeps the stick rebounding in the pad, with minimal movement of the thumb. A little bit of wrist, of course, as he said, but mostly thumb.
Joe Morello said, of course we use the wrist and forearm, they are there , and of course, they are going to move.
But there are different techniques that concentrate in wrist, and fingers.
Wrist involves the pendulum effect of the wrist and thumb, making the pendulum effect for a continuous movement of the stick with minimal effort. The hand gets totally open for that movement to be maximized, without the limitation of the position of the index and hart finger being on top of the stick.
Finger technique is were the stick still rests in the hand cradle, but the index is continuously moving the stick down, the stick rebounds up and the index puts it down again, creating, again, a pendulum effect.
Its like taping a table with your index, just between the index and thumb, there is the stick.
