Leo was born in San Vito degli Schiavoni (current San Vito dei Normanni, province of Brindisi), then part of the Kingdom of Naples.
He became a student at the Conservatorio della Pietà dei Turchini at Naples in 1703, and was a pupil first of Francesco Provenzale and later of Nicola Fago. It has been supposed that he was a pupil of Pitoni and Alessandro Scarlatti, but he could not possibly have studied with either of these composers, although he was undoubtedly influenced by their compositions. His earliest known work was a sacred drama, L'infedelta abbattuta, performed by his fellow-students in 1712.
