Abstract
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.
