A drumhead is the membrane stretched over the top of a drum, which produces sound when struck. It can be made from various materials, including animal skin or synthetic substances, and comes in different sizes and thicknesses. The type of drumhead affects the drum's tone, volume, and overall sound quality. Drumheads are essential components of many percussion instruments, such as snare drums, bass drums, and tom-toms. They can be tuned by adjusting the tension around the edges, allowing musicians to achieve their desired sound. Proper maintenance and replacement of drumheads are crucial for optimal performance.
