Page "Musical notation" Paragraph 7

The seven standard note names in Byzantine " solfege " are: pá, vú, g < sup > h </ sup > á, d < sup > h </ sup > ē, ké, zō, nē, corresponding to Western re, mi, fa, sol, la, si, do.

Byzantine music uses the eight natural, non-tempered scales called Ēkhoi, " sounds ", exclusively, and therefore the absolute pitch of each note may slightly vary each time, depending on the particular Ēkhos used.

Byzantine notation is still used in many Orthodox Churches.

Some cantors can also use standard Western notation while adding non-notatable embellishment material from memory and " sliding " into the natural scales from experience.
