ABSTRACT:
A button actuated chord selector and playing device for simultaneously pressing a plurality of selected strings of a stringed musical instrument, such as a guitar, against the spaced frets of the instrument to shorten the vibrational length of the strings, to increase the pitches of the instrument, and, thereby, to produce selected harmonizing chord sounds. Each button operates its related actuating bar extending parallel with the neck of the instrument, and each of those actuating bars is operably connected to actuate a plurality of transversely extending selector bars positioned at different positions longitudinally on the neck of the instrument to engage and press selected strings against the spaced frets to produce the selected chord. Laterally spaced guide pins are provided at opposite ends of the actuating and selector bars to limit movement of the bars and to keep opposite ends of the bars moving in unison. Springs positioned at opposite ends of the bars are provided to lift the actuating and selector bars when the buttons are released.
