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 tone and quality of sound produced by the drum, making it an essential component in percussion instruments. Drumheads are commonly used in various types of drums, such as snare drums, bass drums, and tom-toms. Musicians can also adjust the tension of the drumhead to change the pitch and resonance, allowing for a wide range of sounds in musical performances.
