alteration of the actual neumes, varying only the starting pitch. List of works This list is incomplete. Most of the works are included in the collection of the Archive of the Elders on the island of Syme, Ms. 341, but the last part of the collection was destroyed, the Mathematarion of the Menaion is damaged after January (only the first half has survived), and the main collection of heirmologion kalophonikon is missing, except some kalophonic settings of Theotokia which had been arranged in octoechos order. The heirmoi kalophonikoi are mainly known in the printed exegesis by Gregorios the Protopsaltes, while Oktaecha cycles (cherubikon and Sunday koinonikon) are better known according to the transcription made by Chourmouzios, but both teachers at the Music School did an almost complete transcription of Bereketis' compositions. It proves that they were already appreciated at the Patriarchate by the turn to the 19th century. It should be also mentioned that there was an own Romanian reception since the 17th century especially of the heirmologion kalophonikon, which was taught in Jassy by Dionysios Photeinos and also Gregorios the Protopsaltes had to move there.
