Piano chord producing bars

Abstract

This disclosure concerns an input keyboard which works in unison with a compatible operating program to produce piano chords. The keyboard incorporates strategically placed pairs of actuator switches that are tied together in unison by a lengthways-positioned rectangular bar that is attached on top of each one of the actuator switches by a flexible fastener means with each actuator switch being attached directly underneath each end of the rectangular bar. This conglomeration is referred to as a Piano Chord Producing Bar. Each piano chord producing bar is programmed to produce full or partial piano chords when depressed. Piano chord producing bars are plurally arranged in horizontal parallel rows that extend from the left to the right side of the keyboard. Piano Chord Producing Bars keyboards with their compatible operating programs can be incorporated into electronic keyboard musical instruments or used as controller keyboards for input into various devices.
