Welcome to
Trisagion School
of Byzantine Music

"A psalm consoles the sad, restrains the joyful, tempers the angry, refreshes the poor and chides the rich man to know himself. To absolutely all who take it, the psalm offers an appropriate medicine; nor does it despise the sinner, but presses upon him the wholesome remedy of penitential tears."

~St. Niceta of Remesiana

Trisagion School of Byzantine Music is an online Byzantine Chant training program that was founded in 2020 by Samuel Herron, Amy Hogg, and Gabriel Cremeens. Its mission is to offer Byzantine Chant instruction in English with a focus on the ever-growing English-language repertoire available in Byzantine notation. 

Trisagion School offers flipped-classroom online courses to train students in all the necessary skills to become a competent chanter. The comprehensive curriculum teaches vocal performance, Byzantine notation, the hymns of the Resurrectional Octoëchos, model melodies, the hymns of the Great Feasts, the use and application of the Typikon, and advanced papadic repertoire.
