Summarize the following:
Matched grip position is the starting position in which you hold your drumsticks. Grip the stick by hooking your pointer finger around the stick, and grasping the stick with the pad of your thumb. You should be holding the stick approximately 4 inches from the bottom of the stick. Then wrap your other three fingers around the drumstick. The drumstick should be gently (but securely) resting in the palm of your hand. Normally when drumming, your hands (and sticks) are in a horizontal position. For the spin, turn your hand so you're holding the drumstick vertically. Remain holding the drumstick with your pointer finger and thumb. Put your middle, ring, and pinky fingers behind the stick while still keeping the drumstick vertical.
Hold the stick in matched grip position. Position your hand vertically. Pinch the stick and release your other fingers.
