chord organ

A chord organ is an electronic or reed organ that features buttons for producing simple chords. This distinguishes it from a string organ, which uses vibrating strings to produce musical tones. Chordophones, a broader category, are instruments where a stretched string creates the initial sound. Organs, in general, are keyboard instruments that use pipes or reeds to create sound when wind is supplied. While early organs were complex and expensive, simpler reed organs like the harmonium and melodeon were developed in the 19th century. These have largely been replaced by electronic instruments and synthesizers.12345
