The music of Greece is as diverse and celebrated as its history. Greek music separates into two parts: Greek traditional music and Byzantine music. These compositions have existed for millennia: they originated in the Byzantine period and Greek antiquity; there is a continuous development which appears in the language, the rhythm, the structure and the melody. Music is a significant aspect of Hellenic culture, both within Greece and in the diaspora.

Music was an important part of education in ancient Greece, and boys were taught music starting at age six. Greek musical literacy created a flowering of development; Greek music theory included the Greek musical modes, eventually became the basis for Eastern and Western religious music and classical music. Roman era Due to Rome's reverence for Greek culture, the Romans borrowed the Greek method of 'enchiriadic notation' (marks which indicated the general shape of the tune but not the exact notes or rhythms) to record their music, if they used any notation at all. Byzantine era The tradition of eastern liturgical chant, encompassing the Greek-speaking world, developed in the Byzantine Empire from the establishment of its capital, Constantinople, in 330 until its fall in 1453.
