The music of Greece is as diverse and celebrated as its history. Greek music separates into two parts: Greek traditional music and Byzantine music, with more eastern sounds. These compositions have existed for millennia: they originated in the Byzantine period and Greek antiquity, where there is a continuous development which appears in the language, the rhythm, the structure and the melody. Greek music has many similarities with the music of Cyprus, their modern popular music scenes remaining well-integrated with one another. Music is a significant aspect of Hellenic culture, both within Greece and in the diaspora.
