Drumsticks are instruments used to beat drums and hang cymbals. There are hundreds of different types and models of hammer. Among so many varieties, there are four basic models that each brand will provide: light and thin 7a, general 5A and 5b, and heavier 2B.
Whether to use a light or heavy drumstick depends on many factors. Generally speaking, power drummers use heavier drumsticks to make heavier sounds, and heavier cymbals also need to use heavier drumsticks to make good sounds. Similarly, deeper drums require heavier hammers. It should be noted that the heavy drumstick is not suitable for thin cymbals. The heavy drumstick is likely to crack the cymbals.
The balance of drumstick is related to weight distribution; The shorter conical part and the thicker mallet neck part will tilt the weight forward, so that the feeling and sound of the drumstick have a sense of weight, and vice versa. The balance of the drumstick depends largely on your grip and the way you play.
