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

About Us

Logo for Website

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. 

In addition to online group courses, the instructors also offer private lessons in their various areas of expertise, including Byzantine chant composition and repertoire in Greek and Spanish. Instruction is offered in various languages; see our Private Lessons page for more details.

I have chanting experience and have studied with another teacher or school. Do I need to start with ByzB 101?

You may test into a later class by recording the Capstone Project hymn of the prerequisite class on parallagi and melos.  If you demonstrate mastery of the Capstone project hymns you will be placed in the next class.  Contact us to discuss the particulars.
