Manos Hatzidakis was a Greek composer and theorist of Greek music, widely considered to be one of the greatest Greek composers. He was one of the main proponents of the "Éntekhno" form of music, along with Mikis Theodorakis, is the founder of the Orchestra of Colours, an ensemble performing lesser-known works and the music of Greek composers, and influenced a broad swathe of Greek culture through his writings and radio broadcasts.

Éntekhno is orchestral music with elements from Greek folk rhythm and melody. Its lyrical themes are often based on the work of famous Greek poets. Éntekhno arose in the late 1950s, drawing on rebetiko's westernization by Vassilis Tsitsanis and Manolis Chiotis. Mikis Theodorakis and Manos Hatzidakis were the most popular early composers of éntekhno song cycles.
