He was born in Milan, son of Luigi Giorza, a painter and singer. His father prompted his musical interest. He is revered in Milan, where he wrote the song "La bella Gigogin [it]" in 1858, performed at the Milan Carcano Theatre. The song became symbolic of Italian culture.
During his lifetime, he produced and wrote many scores including various waltzes. Giorza travelled much of the world working in Venice, Vienna, London and Paris.[3] In the late 1860s he worked in America, directing the orchestra at the Academy of Music in New York City. He composed the music for the cancan dance, introduced to America by his friend and fellow Milanese artist, ballerina Giuseppina Morlacchi. In 1871 he went to Australia where he succeeded as a composer. In 1884, he became unwell and returned to Europe and success at La Scala. He died on 4 May 1914.
