Fit in 15 Minutes is intended for occasional players who are very short of time and want to maintain and improve their violin technique in a concentrated and effective quarter of an hour. They can also be used at the beginning of a longer practice or rehearsal session.

As the technical precondition of beginners and professional violinists 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 identify correlations, to polish basics or to conquer new technical challenges.
