Fit in 15 Minutes is intended for occasional players who are very short of time and want to maintain and improve their viola technique in a concentrated and effective quarter of an hour. They can also be used at the beginning of alonger practice or rehearsal session. As the technical precondition of beginners and professional violists vary, each exercise is offered in three levels of progressive complexity: ■ Level 1: Exercises for beginners ■ Level 2: Exercises for advanced players ■ Level 3: Exercises for tertiary students and professionals The division in three levels provides didactic transparency. It is not meant to create boundaries, but serves as a stimulation to identifycorrelations, to polish basics or to conquer new technical challenges.
