Drumheads are the membranes stretched over the top and bottom of a drum, which produce sound when struck. They can be made from various materials, including animal skin and synthetic materials like polyester. The type of drumhead affects the drum's tone, volume, and overall sound quality. There are two main types of drumheads: batter heads, which are struck by the drummer, and resonant heads, which enhance the drum's sound. Different styles of music may require specific drumhead types, such as those used in rock music or jazz. Proper maintenance and tuning of drumheads are essential for optimal performance.
