The perfect fourths layout as a superior contrapuntal instrument
Frank is currently developing a curriculum model for the keygrid and will publish updates on this website after stages of completion.
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.
About performance dynamics in regard to pad/key depression and velocity:
'The touch-sensitive pads I currently use are not ideal velocity function. I actually often limit the velocity on them, because the calibration of velocity touch doesn't feel exactly right. But this is due to my feel of the pads and tech, not the keygrid layout.'
Instrument manufacturers would have to consider the depression of keys and velocity function towards a true standardization of the keygrid (perfect fourths contrapuntal layout) instrument. 'I would propose a relatively shorter distance from key press to strike than the keyboard. This changes the performance dynamics to a degree, yet accommodates expression for the larger interval range available for each hand (without changing position) respectively.
Also, new models can explore a mild, perhaps convex elevation of the black keys, and possibly an even more mild concave depression in the white keys - to provide tactile, isomorphic purposes for the keygrid interface.'
