The bow school Billy Bogen & Gwindi Greifhand – Expedition mit dem Cellobogen is aimed at 6 to 12 year old children from the 1st year of lessons. It can accompany the pupils' training over a long period of time and offers an ideal supplement to any cello tutor, as the basics of cello technique are deepened here in 88 exercises.

The focus is on the development of the bow hand. With scales, triads and thirds over 1 - 2 octaves, six of the most important stroke types are trained. The imaginative approach to the technical subject is essential here, to which the lovely illustrations by Anette Bley in particular also contribute.
