A drum set is a collection of percussion instruments that includes a KIT, rolls, ears, TIMPANI, and traps. A KIT is a set of drums, cymbals, and other percussion instruments that are played by a single drummer. Rolls are a type of drum beat that is repeated in a steady rhythm. Ears are the two small drums that are mounted on either side of the KIT. TIMPANI are large drums that are usually played with mallets. Traps are a variety of percussion instruments such as cymbals, woodblocks, and cowbells that are used to add texture and color to a drum set.
