Clarinet Warmups are based upon Christopher Weait's highly successful Bassoon Warm-Ups (published by Emerson Edition.)
Warming up is as important for musicians as it is for athletes. It helps prepare the body and mind to perform efficiently by reducing tension and encouraging a state of relaxed attention.
These warmups emphasize legato playing - the basis for good tone, good pitch, good coordination and, surprisingly, good articulation. In addition to warming up your instrument, fingers and ear, they gradually expand range, breathing endurance, dynamic levels and rhythmic awareness. Warming up will allow you to notice if your reed or instrument need adjustment before continuing to play.
Doing the warm-ups every time you play builds confidence and reduces stress.
In the words of clarinetist John Kurokawa they "ease you into playing."
