During the American Legion National Convention in the year 1933 there where a couple of prominent drummers who founded the N.A.R.D. The National Association for Rudimental Drummers.
Their purpose was not invent de standard rudiments but their intension was to review the earlier invented rudiments which came originally from Switzerland 200 years before 1933, when music notation was not yet standardized. The rudiments were introduced in the United States during the American revolution. Slowly the rudiments found their way from Switzerland through France to England. The main reason to write these rudiments was to standardize a system by selecting some of these rudiments to judge all corps and drummers. We refer to them as the “Thirteen Essential Rudiments.” These were chosen from the 26 rudiments as a minimum to become member of this association.
