The 20 Minute Warm-Up Routine is a dynamic, comprehensive set of 15 exercises and 15 play-along tracks that will both warm you up and work you out. This routine will absolutely energize your practice routine. It gives you the opportunity to play along with and emulate four of the world's finest brass players. Whether it's Phil Smith on trumpet, Chris Komer on french horn, Michael Davis on trombone or Gene Pokorny on tuba, the 20 Minute Warm-Up gives you examples to strive for in a fresh and innovative way. We highly recommend using both this routine and the more fundamental 15 Minute Warm-Up Routine. Book purchase includes book and play-along CD.
