Centuries old, Byzantine Chant is the traditional liturgical music of the Greek Orthodox Church.
The chant is monophonic, that is, it consists of a single melodic line with no harmonization, and is accompanied by a vocal drone called isokratima(literally "holding the same").
The music on this recording is primarily influenced by the theory of performance practice developed by Simon Karas in the mid-to-late twentieth century in Athens.
The music was adapted from the Anastasimatarion, and Mousikos Pandektes, both published by Zoe in Athens, and Simon Karas' Methodos, also published in Athens. A portion of the Anoixandaria, (the chanting of the last 10 verses of Psalm 103), was presented to demonstrate their use in special feast days or vigils.
