Greg has been researching psychoacoustics and its relationship to music theory since 2008. In 2014 he published his doctoral dissertation entitled Psychoacoustic Entropy Theory and Its Implications for Performance Practice. This document examined the inconsistencies inherent in various historical approaches to modeling consonance and dissonance perceptions of musical harmony. As part of his research, Greg proposed a new way of combining various models from psychoacoustics and information theory to gain a deeper insight into how the human auditory system might process harmonic information.

Since 2014, Greg has been focusing his research on a specific idea introduced in his 2014 dissertation called Tonalness Theory. By Greg’s definition, tonalness is a mathematical model for the information content of human hearing. Greg’s most current Tonalness Theory research can be retrieved here.
