Giuseppe Verdi was born Giuseppe Fortunino Francesco Verdi on October 10, 1813, in Le Roncole di Busseto, Parma, Italy. His parents were landowners and innkeepers. Young Verdi received his first organ lessons at the age of 7. He studied composition privately with Ferdinando Provesi in Busseto. At age 20 he moved to Milan to continue his studies, but the Conservatory of Music rejected him. Verdi took private lessons and associated with Milan's cultural milieu in his pursuit of a musical career. He was patronized by Antonio Barezzi, a merchant, whose daughter, Margherita, was Verdi's student and later became his wife. Verdi's musical success coincided with the political events of Italian unification during the Austrian occupation. The 'Chorus of the Hebrew Slaves' from his opera 'Nabucco' (1842), became a popular song among supporters of Italian unification. Many of his opera performances were used by the supporters of Victor Emmanuel to shout "Viva Verdi" as a code name for a secret unification message. The name Verdi was used as acronym for "Vittorio Emanuele Re D'Italia" - Victor Emmanuel, King of Italy. Such a code enabled clandestine partisans of Victor Emmanuel, then the King of Sardinia, to gain more supporters in Milan which eventually led to the unification of Italy. Verdi was aware that his popular operas and his name was used as a political tool. Austrian censorship was powerless. Verdi's music was used in hundreds of film scores. His operas has been the staples of operatic repertoire. His canzonas "La donna è mobile" from opera 'Rigoletto' (1851) and "Libiamo ne'lieti calici" (Drinking song) from 'La Traviata' (1853) has been popular concert numbers in performances by the three tenors: Luciano Pavarotti, Plácido Domingo and José Carreras.
