The perfect fourths layout as a superior contrapuntal instrument


A keygrid (as opposed to keyboard) is a contrapuntal instrument with the notes arranged vertically in perfect fourths, and horizontally as chromatic. It is playable with two hands like a piano [or organ, harpsichord, or any other keyboard instrument], but with a system of notes matching the guitar in perfect 4ths tuning, a bass guitar, double bass, etc.


As a new standard, electronic and hybrid models will take centre stage in the upcoming musical era.
