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.
Rudimental drumming has something of a flexible definition, even within drumming societies devoted to that form of drumming. For example, the longest running website on rudimental drumming defines it as "the study of coordination," whereas the Percussive Arts Society defines rudimental drumming as a particular method for learning the drums—beginning with rudiments, and gradually building up speed and complexity through practicing those rudiments. (An analogy might be made to learning the piano by first learning scales and arpeggios, as opposed to beginning by taking a full piece of music and grinding through it bit by bit, to the end.)
The origin of snare 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 first written rudiment goes back to the year 1612 in Basel, Switzerland. The cradle of rudimental drumming is said to be France, where professional drummers became part of the King's honour guard in the 17th and 18th centuries. The craft was perfected during the reign of Napoleon I. Le Rigodon is one of the cornerstones of modern rudimental drumming.
There have been many attempts to formalize a standard list of snare drum rudiments. The National Association of Rudimental Drummers, an organization established to promote rudimental drumming, put forward a list of 13 essential rudiments, and later a second set of 13 to form the original 26. In 1984, the Percussive Arts Society reorganized the first 26 and added another 14 to form the current 40 International Drum Rudiments. Currently, the International Association of Traditional Drummers is working to once again promote the original 26 rudiments.
