Tonalness Theory

Greg’s research since his 2014 has been primarily into something he calls Tonalness Theory. Tonalness Theory defines a mathematical quantity called tonalness that can be calculated directly from any sound wave. Tonalness can be used to model the information content of human hearing and give us new insights into our perceptions of harmony, intonation, and timbre in both musical and non-musical settings.

For a more mathematically rigorous introduction to Tonalness Theory, please consult the Introducing Tonalness Theory paper and Tonalness Equations document.
