Abstract: The Thumb Bar Controller is a bar that runs the width of the electronic musical keyboard playing area, (plus whatever is needed for the lever attachment), connected by two armsrests just below the top, and approximately one inch away from the keys. It gives the performer control over two (or more) functions with the thumb of the playing hand, that would otherwise require the other hand or foot pedals, allowing a person with the disabilty of one arm/hand, to be as proficient as a person with two. It can be used for controlling pitch bend, modulation, MIDI specification controllers, various electronic controls, and product specific controls. The bar can be attached in numerous ways, could use a variety of spring type mechanisms to control it. It can be mounted externally or made as an integral part of the keyboard, with openings for the bar connections and movement required.
