He soon achieved success and fame among young Italian musicians: operas, chamber music, symphonic music, a comic opera "La serenata al vento", a dramatic work inspired by anti-Semitic persecution, "Shylock", which remained unfinished and was performed in this form (Milan and Marseille), are among his compositions.
In the 1931 Ricordi catalogue, his compositions include "Il chiostro" for female voices and orchestra, the symphonic poems "Cirano di Bergerac", nominated in a competition whose judging panel included Arturo Toscanini and Ildebrando Pizzetti, and "Inni alla notte", a "Sonata for violin and piano" (now published by Suvini & Zerboni), a "Quartet for strings", various lyrics (Barque d'or, Serenata), a comic comedy in three acts, precisely "La serenata al vento" (published by Ricordi).
In 1939 he wrote a symphonic poem ("Come all'ultimo suo ciascuno artista"); in 1940 he composed "Danza", a concert for 2 pianos, saxophones and orchestra; in 1942 "Shylock", a dramatic opera with a libretto by Rossato.
His music has now been performed - in addition to many cities in Italy - in almost the entire European continent, as well as in the USA, Canada, Panama, Mexico, Israel, Japan, Australia....
Following recent great successes at Carnegie Hall (the latest of which featured guest star Plácido Domingo), the American press has defined Finzi as “the Italian Strauss”.
