He made his debut as a jazz piano player, already in 1940, when he was fifteen, playing, in secret, in a student jazz little orchestra.
In 1944 he joined RAI, as a piano player for Piro Piccioni's Orchestra.
Then he gained great success abroad, particularly in Northern Europe, experimenting with a mix of jazz, Neapolitan songs and his own pieces. Fortified by gained consents, when he came back to Italy in 1958, composed songs for Caterina Valente, Renato Rascel e Wilma De Angelis.

There isn't a player of jazz in the world who has not executed once in his life "Estate", a longing piece carried to international fame by Brazilian guitar player Joao Gilberto, who discovered it during an Italian tour, re-arranged it in a "bossa" version and made it a standard, today one of the most executed. Its most famous versions are by Chet Baker, Toots Thielemans, Michel Petrucciani, Mike Stern; among the Italians who interpreted "Estate" there are Mina, Mia Martini, Ornella Vanoni, Vinicio Capossela, La Crus, Irene Grandi and Sergio Cammariere.
