Works.
With 18 years of hard labour, Chourmouzios explained all the melodies of the ancient composers, from Saint John of Damascus until Manuel Protopsaltes. These consisted of 70 volumes, which were bought in 1838 by Patriarch Athanasius of Jerusalem, and were looked after Cyril II, archpriest of the Sion Church. He compressed them into fewer volumes and ordered that they be bound and kept into the library of the Holy Sepulchre in Phanar, where they are currently present.
He edited as long as he lived the publication of his following works:
In the National Library of Greece there are 34 of his manuscripts (codes and volumes).
