Prior to the release of his 12 Etudes for Snare Drum in 1964 there was very little in the way of orchestral-style snare drum repertoire. Percussionists were mostly left to study orchestral excerpts and rudimental solos. These etudes, which were inspired by orchestral repertoire, made the study of technique less about gym-style exercise and repetition and more about musicality, expression and finesse.
It would behoove any serious percussionist to spend some time with this material, no matter where your musical interests lie.
Merci beaucoup, Monsieur le Delécluse!
