Drum rudiment
（重定向自Paradiddle）
In percussion music, a rudiment is one of a number of relatively small patterns which form the foundation for more extended and complex drum patterns. The term "rudiment" in this context means not only "basic", but also fundamental. While any level of drumming may, in some sense, be broken down by analysis into a series of component rudiments, the term "drum rudiment" is most closely associated with various forms of field drumming, also known as rudimental drumming.
