This article is about the Byzantine musical system of eight modes.
For the book of liturgical texts set to those modes, see
Octoechos (liturgy).
Oktōēchos (here transcribed "Octoechos"; Greek: ὁ Ὀκτώηχος [ modern Greek: oktoˈixos, old Greek: oktɔːˈɛːkʰos ], from ὀκτώ "eight" + ἦχος "sound, mode" called echos; Old Church Slavonic: Осмогласие, Osmoglasie from о́смь "eight" and гласъ, Glagolitic: ⰳⰾⰰⱄⱏ, "voice, sound") is the name of the eight-mode system used for the composition of religious chant in Byzantine, Syrian, Coptic, Armenian, Latin and Slavic churches since the Middle Ages. In a modified form the octoechos is still regarded as the foundation of the tradition of monodic Orthodox chant today.
Nomenclature
The names ascribed to the eight tones differ in translations into Church Slavonic. Тhe Slavonic system counted the plagioi echoi as Glas 5, 6, 7, and 8. For reference, these differences are shown here together with the Ancient Greek names of the octave species according to the Hagiopolites[1] and to the chant treatises and tonaries of Carolingian theorists. Please note that 15th-century composers like Manuel Chrysaphes, Lampadarios at the Court of Palaiologan Constantinople, exchanged the Phrygian with the Lydian. The Armenian names and their temporal cycles are represented in the article about the hymn books octoechos and parakletike.
