Fit in 15 Minutes is aimed at musicians who do not play much, who never have enough time and wish to maintain and improve their cello technique in a concentrated and efficient quarter-hour, as well as at musicians who play much as beginning of a lengthy practice or rehearsal phase. The exercises contained in this volume range from very easy exercises - some even on open strings only - to short extreme exercises which can be combined to form an individual programme at various levels of difficulty. / Violoncelle
