Drummer Peter Erskine on Jazz Flick 'Whiplash' wrote:I've played under the baton of stern and demanding conductors, as well as the critical ears of some pretty tough bandleaders. I've always experienced equal amounts of praise and criticism from the toughest of them. A conductor or bandleader will only get good results if he or she shows as much love or enthusiasm as the discipline or toughness they dole out. Being a jerk is, ultimately, self-defeating in music education: for one thing, the band will not respond well; secondly, such bandleaders are anathema to the other educators who ultimately wind up acting as judges in competitive music festivals -- such bands will never win (the judges will see to that).
