Abstract
In a chord progression input/modification device, when a key and a single or two successive reference chords are designated by a user, available chords are acquired and displayed. Any one of the available chords can be used, in consonance with musical theory, to follow or substitute for the single reference chord, or to be inserted between the two reference chords for generating a modified chord progression. The chord progression modification device may be installed in an electronic musical instrument.
