In rudimental drumming, a form of percussion music, a drum rudiment is one of a number of relatively small patterns which form the foundation for more extended and complex drumming patterns. The term "drum rudiment" is most closely associated with various forms of field drumming, where the snare drum plays a prominent role. In this context "rudiment" means not only "basic", but also fundamental. This tradition of drumming originates in military drumming and it is a central component of martial music. Rudimental drumming has something of a flexible definition, even within drumming societies devoted to that form of drumming. RudimentalDrumming.com defines it as "the study of coordination." The Percussive Arts Society defines it as a particular method for learning the drums—beginning with rudiments, and gradually building up speed and complexity through practicing those rudiments. Camp Duty Update defines a drum rudiment as an excerpt from a military call with a definite rhythm, definite sticking, definite dynamic structure (accents), and a defined nomenclature. Encyclopedia Rudimentia defines a rudiment as a short pattern of strokes, using John Pratt's logic that "the rudiments of drumming are strokes," in reference to the four basic drum strokes. The origin of snare drum rudiments can be traced back to Swiss mercenaries armed with long polearms. The use of pikes in close formation required a great deal of coordination. The sound of the tabor was used to set the tempo and communicate commands with distinct drumming patterns. These drumming patterns became the basis of the snare drum rudiments. The earliest instance of rudimental fife and drum is often cited as the Swiss military at the battle of Sempach in 1386. There is evidence, however, that the Swiss were already using drums in battle in 1315 at the Battle of Morgarten. Initially, Swiss rudiments were very influential to the French system, which in turn was the basis for many other rudimental systems.
