Drums work by producing sound when the player strikes the drumhead with their hands or drumsticks. The drumhead is a stretched membrane that is attached to the drum shell, which is the hollow body of the drum. When the drumhead is struck, it vibrates and produces sound.
The pitch of the drum is determined by the size and tension of the drumhead, as well as the size and shape of the drum shell. Larger and tighter drumheads produce higher pitches, while smaller and looser drumheads produce lower pitches. The type of drumsticks and how they are struck also affect the sound of the drum.
In an acoustic drum set, the drumheads are struck directly with drumsticks, and the sound is produced naturally by the vibration of the drumheads. In an electronic drum set, the drumheads are replaced by electronic pads that are connected to a drum module. When the pads are struck, they send a signal to the drum module, which produces the desired sound.
Overall, drums work by producing sound through the vibration of the drumhead when struck. The pitch and timbre of the drum can be controlled by adjusting the size, tension, and materials of the drumhead and shell, as well as by using different playing techniques.
