In page Nino Rota:

"

Rota was born Giovanni Rota Rinaldi on 3 December 1911, into a musical family in Milan. Rota was a renowned child prodigy—his first oratorio, L'infanzia di San Giovanni Battista, was written at age 11[1] and performed in Milan and Paris as early as 1923; his three-act lyrical comedy after Hans Christian Andersen, Il Principe Porcaro, was composed when he was just 13 and published in 1926. He studied at the Milan conservatory there under Giacomo Orefice[2] and then undertook serious study of composition under Ildebrando Pizzetti and Alfredo Casella at the Santa Cecilia Academy in Rome, graduating in 1930.[3]
