Rudiments: Geography, History, and Evolution
Rudiments are typically just accepted exactly as taught, without much question. The current standard selections are encompassed in the PAS 40 International Snare Drum Rudiments list. What many drummers do not know is that rudiments are ancient and there are many more than just the 40. For a list of almost all known rudiments (850+) be sure to check out my book Encyclopedia Rudimentia, published by Hudson Music. The following articles or essays should help illuminate a few small facets of the massive, yet understudied, topic of historical and international rudimental drumming.
