In 1954 he travelled with his young wife Myrto Altinoglou to Paris where he entered the Conservatory and studied musical analysis under Olivier Messiaen and conducting under Eugene Bigot.
His time in Paris, 1954–1959, was his second period of musical writing.

His symphonic works: a Piano concerto, his first suite, his first symphony, and his scores for the ballet: Greek Carnival, Le Feu aux Poudres, Les Amants de Teruel, received international acclaim.
In 1957, he won the Gold Medal in the Moscow Music Festival; President of the Jury was Dmitri Shostakovitch.
In 1959, after the successful performances of Theodorakis's ballet Antigone at Covent Garden in London, the French composer Darius Milhaud proposed him for the American Copley Music Prize - an award of the "William and Noma Copley Foundation", which later changed its name to "Cassandra Foundation" - as the "Best European Composer of the Year".
His first international scores for the film Ill Met by Moonlight and Luna de Miel, directors: Michael Powell and Emeric Pressburger, were also very successful: The Honeymoon title song became part of the repertoire of The Beatles.
