LEO, LEONARDO. - Musician, b. at S. Vito degli Schiavi (dei Normanni) on 5 Aug. 1694, d. at Napoli on 31 Oct. 1744. He studied at the conservatory of the Pietà, where in 1712 he was appointed “masticello”; in 1739 he succeeded Feo at the conservatory of S. Onofrio, while also continuing to teach at the Pietà. Among his pupils were Piccinni and Jommelli. He was organist of the Royal Chapel and of the Cathedral.
A prolific composer, he wrote about 80 operas, which made him deservedly famous and cause him to be considered one of the finest glories of the Neapolitan school, of which he was among the most illustrious founders. Eight oratorios and abundant sacred music, as well as pieces for various instruments, are admirable compositions for their loftiness of form and religious feeling, although they reflect the period in which they were composed. Many of his works are in manuscript in the libraries of Italy and Europe; others have been printed in numerous modern editions.
