Born in Padua, Silvio Omizzolo received his piano diploma in 1927 in Milan under the guide of Renzo Lorenzoni. In the meantime, he completed his studies at the Liceo Classico Tito Livio in Padua and graduated in Law at the University of Ferrara.

A self-taught composer, he received great support from the encouragement and advice of Almerigo Girotto, to whom he was bound with a deep and sincere friendship. His first compositions date back to 1928. Later he composed several piano works and pieces for different vocal and instrumental formations.

In 1943 Silvio Omizzolo was awarded 1st prize at the Italian Musician's Union Competition. This was followed by numerous important awards, including 3rd prize at the Queen Elisabeth International Competition (1969) with his Piano Concert. Many of his compositions, some of which published by Zanibon and Ricordi Edition, have been performed in public and broadcasted by Italian television.

In addition to his compositional activities, he was also a brilliant soloist and tireless teacher. His recitals as soloist, in piano duo and in various chamber music groups have been often recorded and transmitted on radio.

Silvio Omizzolo was head piano teacher from 1933 to 1974 at the Music Conservatory C. Pollini of Padua. He was also Director of the same school from 1966 to 1971, actively contributing to its transformation into a Public Conservatory. His didactic activity took place also at the Music Conservatory Francesco Canneti in Vicenza and Benedetto Marcello in Venice.
