Giuseppe Fortunino Francesco Verdi was an Italian Romantic composer, mainly of opera. He was one of the most influential composers of the 19th century. His works are frequently performed in opera houses throughout the world and, transcending the boundaries of the genre, some of his themes have long since taken root in popular culture – such as "La donna è mobile" from Rigoletto, "Va, pensiero" (The Chorus of the Hebrew Slaves) from Nabucco, "Libiamo ne' lieti calici" (The Drinking Song) from La traviata and the "Grand March" from Aida. His work has sometimes been criticized for using a generally diatonic rather than a chromatic musical idiom and for being essentially melodrama during his early years. He was an atheist. Verdi’s masterworks dominate the standard repertoire a century and a half after their composition.
