House music is a style of electronic dance music that originated in Chicago, Illinois, United States in the early 1980s. It was initially popularized in mid-1980s discothèques catering to the African-American, Latino American, and gay communities; first in Chicago circa 1984, then in other cities such as New York City, Toronto, Montreal, London, Detroit, San Francisco, Los Angeles and Miami. It then reached Europe largely due to the infamous House Music Tour visiting England. England played a pivotal role in the development of house music throughout Europe. Since the early to mid-1990s, it has become infused in mainstream pop and dance music worldwide.
