Abstract
The present invention is a chromatic-emphasis hybrid-diatonic leverless keyboard configured to provide an extension, duplication, or representation of both heptatonic and pentatonic keys on the leverless keyboard. The extension enables the user to shift the physiological center of gravity for the keyboard to the area where pentatonic and heptatonic keys share space and are more isomorphic, thus assisting in gaining and applying understanding of the chromatic equality of the twelve tonalities in standard equal temperament, and in gaining and applying understanding of the one-dimensional nature of music.
