The Great Octoechos (Paraclitiki) contains the Propers for Vespers and Orthros throughout the liturgical year, arranged according to the eight Byzantine tones. This complete four-volume set provides the full cycle of hymns and services, with each volume covering two of the eight tones.

Each edition is spiral-bound for durability and designed to lay flat for convenient use on cantor’s stands. A foundational resource for Byzantine chant, this collection is ideal for clergy, cantors, and choirs seeking to faithfully follow the weekly cycle of tones.
