Holding rod method

In terms of control: there are three main ways to hold the lever. They affect the inertia between the hand and the stick. The two most important concepts are controlling the stick and waving the stick.

1, straight wrist posture: the thumb, forefinger and middle finger hold the stick at one third of the drum stick, and the ring finger and little finger naturally stick together behind the back, which does not affect the movement of the stick. Keep your palms opposite, pay attention to the symmetry and balance of your hands, and the hitting point of the drum stick should be relatively concentrated. Timpani and trapezoidal xylophone are basically played in this way.

2. Standard style: straight wrist style with right hand, where the left hand grips about one-third of the end of the drum stick and puts it at the joint where the ring finger and the little finger are half-held. The index finger and middle finger naturally bend, and the whole hand is half clenched. Palm inward. The thumb of the tiger's mouth holds the stick, and the ring finger and the little finger hold the stick. The two drums are about 90 degrees. Hit with the left hand with a rotating force. This wrist technique is mainly used to play snare drum Jr. and drums.

3. Wrist buckle type: The holding stick is roughly the same as the straight wrist type, but the hands should be turned inward so that the palms are facing down, and the two drums are concentrated at the high-five point, and the two sticks are at an angle of about 90 degrees. This wrist technique is used to play xylophone, piano, drum set and indoor snare drum.
