The drum rudiments are part of the history of
drumming. They were needed to acquire a certain level of proficiency
on the snare drum and the ability to play the style of music
at that time. Marching drummers played music that had these
types of sticking's in them, so they were standardized very
early in the history of drumming.
As you can see by the images below they were first documented
in 1812... Through the years other drummers came up with their
version and had them copyrighted. Over time there started to
be some confusion as to what was the official set of rudiments
and it often ended in arguments and debates amongst drummers
of that time.
On Dec 10, 1935 N.A.R.D (National Association of Rudimental
Drummers) sent a bulletin to all 246 members with a list of
rudiments to pick from and offer their opinions on what the
standard rudiments should be. 140 members responded to the request
and what you see on the final page is the official Feb. 3, 1936
list adopted by N.A.R.D
So, start practicing! Our drum fathers did this to give us
all the same method for playing and developing proficiency on
the snare drum.
