Byzantine music
Byzantine music (Greek: Βυζαντινή μουσική, romanized: Vyzantini mousiki) originally consisted of the songs and hymns composed for the courtly and religious ceremonial of the Byzantine Empire and continued, after the fall of Constantinople in 1453, in the traditions of the sung Byzantine chant of Eastern Orthodox liturgy. The ecclesiastical forms of Byzantine music are the best known forms today, because different Orthodox traditions still identify with the heritage of Byzantine music, when their cantors sing monodic chant out of the traditional chant books such as the Sticherarion and the Irmologion.
