In his school for drum kits, Gert Bomhof focuses on three essential elements of drum kit playing: timing, technique, and thomann tone. Young drummers are first acquainted with the basic techniques and rules for playing the drum kit, but the emphasis here is not only on technical mastery but also expression. In the first volume, instruments are presented one after the other, then the individual components (or building blocks) thomann of rhythms, and lastly in combinations of different rhythmic patterns. In volume 2, many new rhythms are introduced in turn to the player. In specially developed technical exercises, new rhythms and elements are worked out step by step. In both volumes, new rhythm and technical elements are followed thomann by fun solos and drum kit duets, in which the already learnt material can be put into practise and the musical expression developed.
