DOLORES CATHERINO and host Scot Gresham-Lancaster about the use of a technique called Polychromatic composition that Dolores has identified and uses extensively in her work. Using specially modified keyboards with as many as 72 equal semitones per octave, she creates oceans of sound that sweep the listener into new territories. We discuss using these techniques as a new way to leverage the use of intonation to convey alert, alarm and evn emotional content to the listener by way of the intonational content of converting to these more finely tuned pitch schemas.

Bio: Dolores Catherino is a polychromatic composer and multi-instrumentalist. Her avant-garde compositions use sonic ‘pitch-palettes’ of 106 and 72 EDO (equal divisions of the octave) and are performed on visionary 21st century keyboard instruments. As a musician, she is focused on exploring new sonic worlds within a polychromatic framework which simplifies and unifies our rapidly multiplying microtonal pitch-scale methods. Polychromatic concepts of musical ‘pitch-color’ and ‘interval-color’ are also intended to simplify the exploration of new aesthetic possibilities in the practice of associative synesthetic awareness: learned associations and conceptual/perceptual integration of audible pitch with visual color. With an undergraduate study in music and graduate study in medicine, she hopes to explore and develop integrated perspectives between the sound arts and sciences..
