(Percussion). Each dedicated to a different difficulty level, this set of three books contain snare drum etudes written for each of the 40 rudiments. As a prelude to each etude, there are warm-ups dedicated to the development and mastering of the rudiment it precedes. The overall idea is to have both a technical (the warm-ups) and a musical (the etudes) approach to each of the rudiments. The end result should not only be a mastering of each rudiment, but an applied musicality most often ignored when playing or practicing the rudiments for rudiment's sake.
