Cello Power is a series of books designed to be used to expand the cello student's facility and knowledge of the instrument with a focus on technique and concepts that appear in standard cello repertoire. Most important are the exercises and further recommendations on how to work on them. The process begins with fundamentals that enable the student to build a solid technique in preparation for the difficult passage work ahead. An example is the double-stop excerpts, which are broken down into two-string bow patterns to aid in intonation and to clarify the spacing for the left hand.
