The term 'drum part' refers to two components of a drum set: the RIM and the SNARE. The RIM, which is three letters long, is the outer edge of the drum head that is struck with a stick or mallet. The SNARE, which is five letters long, is a metal-wired drum that produces a sharp sound when struck. Both the RIM and the SNARE are essential components of a drum set and are used to create a variety of rhythms and sounds.
