An Approach to Tonal Plexus Microtonal/Polychromatic Technique by Dolores Catherino

Demonstration of an alternative Tonal Plexus techniques, microtonal pitch layouts and the application of a new polychromatic pitch-color system. 

This 106 equal temperament pitch layout utilizes 2-D, vertically adjacent, discrete key regions which are a fifth apart. This is an alternative to the modified one dimensional (single plane; continuous region) keyboard tuning layouts currently available.

This demonstrated layout enables more efficient and comprehensive technical utilization of the thumb, as well as a compact interval configuration for expanded chordal technique within the hand span.

A left hand optimized tuning layout is also explained, utilizing redundantly tuned (vertically identical pitches) adjacent regions. This left-optimized layout enables a more efficient use of the thumb in left hand scale technique.
