Abstract

A selectable string capo allows a musician to engage one or more strings selectively while the capo is connected to a stringed instrument, while leaving one or more strings disengaged. The capo has at least one plunger and a finger lever allowing a musician to depress the plunger during performance so as to cause the plunger to engage one or more strings. When the finger lever is released, the plunger disengages from the string or strings.
