THE NEO-BYZANTINE does not denote the traditional modes.
The Reform of the Music Notations
Chrysanthos of Madytos (ca. 1770-1846), Gregory the Protopsaltis, and Chourmouzios the Archivist were responsible for a much needed reform of the notation of Greek ecclesiastical music.
Their work consisted of simplifying the complex musical symbols.
Their work is a landmark in the history of the Greek church music, since it introduced the system of neo-Byzantine music notation, upon which are based the present-day chants of the Greek Orthodox Church.
The simplification attracted many believers to study the new Byzantine notation.
