Music of Italy [SEP] Introduction
Instrumental and vocal classical music is an iconic part of Italian identity, spanning experimental art music and international fusions to symphonic music and opera. Opera is integral to Italian musical culture, and has become a major segment of popular music. The Canzone Napoletana—the Neapolitan Song, and the "cantautori" singer-songwriter traditions are also popular domestic styles that form an important part of the Italian music industry, alongside imported genres such as jazz, rock and hip hop from the United States. Italy was also an important country in the development of disco and electronic music, with Italo disco being one of the earliest electronic dance genres.
