Zach Sestili

Zach Sestili is a composer, multi-instrumentalist, singer, performer, and information-technology innovator. As a student of drums, piano, guitar, and saxophone at age ten, he began performing in music groups as a vocalist and instrumentalist, including some of his own songs amidst pop-rock cover songs. By age 16 he was composing and recording full-band arrangements as a solo artist in the styles of progressive rock, pop rock, pop, jazz-fussion, all in a cohesive sound including some modern symphonic orchestration and impressionism. By the end of the 12 years to follow he had composed four lengthy albums of innovative pop-rock music.  

Continuing independant study of harmony theory, he began creating a new approach to explaining the phenomenon of musical harmony, based purely on the physical relationship between the intervals of the modal-scales. He formed a system for defining and organizing common and unknown modes as groups of 7 within a fixed set of 17 spectrums. By this method the modal-scales of musical harmony can be related through their various spectrums of colors. By the end of the 20 years to follow, he discovered a plausible physical relation between the spectrums themselves, manifesting a phenomenon of harmony revealed as Lomality (Location of Modes) which explains why certain modes are suitable together from our perspective.

He now provides a method for fully explaining the mystery of musical harmony in four aspects: Tonentity - an accoustic aspect addressing the interaction of harmonics during harmonization; Modality - the mood-quality that is projected as a characteristic of each partiuclar modal-scale, Lomality - an underlying relationship between modal-scales causing them to be compatible to one-another during a moment of our perceptive focus; and Tonality - a psychological consequence of observing harmony in progression through time, within which we notice recollection, exploration, and resolution thus finding logic and sense between past and future events.
