Basic playing methods of drum set:

1, drumming method:

The snare drum, also known as Little snare drum, is the most important instrument in western atonal percussion instruments and one of the drum groups. The playing posture of the snare drum is also the playing posture of the drum set. In drum playing, because the foot needs to step on the drum and the hairpin at the same time, it is played in a sitting position. When playing, you should have a correct posture, and the upper limbs such as chest, shoulders and arms should be naturally relaxed.

When playing, the arm naturally bends and is placed on the drum surface, and the mallet is held in both hands. The second joint of the thumb and the second joint of the index finger of the right hand hold the handle of the drumstick, the third joint of the thumb and the index finger naturally come together, and the palms of the middle finger, the ring finger and the little finger bend to keep a certain gap with the handle of the drumstick to control the drumstick. The palm of the left hand is inward, the handle of the drumstick is clamped at the tiger's mouth of the thumb and forefinger, and the bottom of the drumstick is supported by the third joint of the ring finger. The other fingers naturally bend into the palm direction to hold the ball. Master the correct mallet holding posture, and also have the correct hitting method. In training, you must remember the word percussion, that is, you must play it.

After the drumstick hits the drum surface, it is necessary to immediately resume the preparatory action when beating the drum. The action of the drum should be completed in an instant, elastic, full of vibration, bright, concentrated, powerful and powerful, and give full play to the sound effect.

2, bass drum stepping method:?

Hit the bass drum with your right foot. Under normal circumstances, the heel steps on the rear end of the pedal, with the ankle joint as the axis, and the forefoot steps on the pedal to drive the drumstick to hit the drum surface. When pedaling, the muscles of thighs, calves and feet relax accordingly, and the hammer should return immediately after hitting the drum surface to form a circular pedaling action. When you play hard, you can hang your feet and tap the pedal with your toes, so that all the weight of your right leg falls on one point, thus strengthening the pedaling force and achieving the expected effect.

3. Step on the hairpin and step on the bullet:

Step on the hairpin and hit it with your left foot. Its main point of play is to step on the ground with the heel at the back end of the pedal, take the ankle joint as the axis, and hit the pedal with the forefoot. When the forefoot is struck, it is not necessary to return immediately, but to control the sustained sound to produce a closed acoustic effect, which is also different from the right foot drum.

4, drum percussion method:

The main points of drum beating are the same as those of small drums. When changing drums, you need to use your wrist to drive the forearm and the forearm to move naturally to other drums to form a natural and coordinated action.
