An attachment for use with a stringed musical instrument comprises a rotatable shaft and groups of one or more string engaging elements coupled to the rotatable shaft. Each string engaging element of a group is positionable in a first orientation for driven rotary engagement with a corresponding string of the musical instrument. Each string engagement element is further positionable in a second orientation. The attachment further includes key actuators operatively associated with the string engaging elements, and each key actuator is manipulable so as to urge each string engaging element of a group into at least one of the first orientation or the second orientation. In an embodiment, the string engaging element(s) operated by each key actuator are rotatable wheels that rotate at a slower rate or a faster rate, depending on whether or not corresponding strings is/are bent toward the corresponding wheel(s).

This invention, a key-changing apparatus for stringed musical instruments, automatically sets all the strings to the necessary flats and sharps for any key signature selected. This allows musicians, particularly novices, to play musical scores in any key signature without having to remember to flatten or sharpen all the multiple notes required by the key signature.

A musical instrument including a vibrating member, such as a string, and a clamping mechanism. The clamping mechanism can include a first clamping member and a second clamping member. The first clamping member and the second clamping member can move between a first, undamped position to a second, clamped position. The clamping mechanism divides the vibrating member into a first portion and a second portion when the clamping mechanism is in the second, clamped position.
