Hypermobility refers to the capability of joints to exceed their medically expected range of motion. In the hands and fingers, this results in weaker connective tissues, causing joint laxity and the inability to properly place the left-hand fingers on the fingerboard. For cellists that have hypermobile fingers, the pedagogy and technique of the left hand must be approached with care through specialized foundational training. Playing the cello involves executing precise, repetitive motions for an extended period of time. Thus, mindlessly repeating a trial and error form of learning will prove futile, for as stretching muscles will allow for a greater range of flexibility, constantly allowing the fingers to become hypermobile will increase the laxity of the joints. This is contrary to the focused and firm strength cellists want in their left-hand fingers. Through the in-depth comparison of medical research in the functional anatomy of the hand and cello pedagogy, I will present an approach to the fundamentals of left hand technique for cellists with hypermobility.
