Chicago House is a genre of electronic dance music that originated in the early 1980s in Chicago. It is characterized by its repetitive beats, synthesized melodies, and use of samples. The genre emerged from the city's vibrant club scene, where DJs began experimenting with new sounds and technology. The music often features a 4/4 time signature and a tempo ranging from 120 to 130 beats per minute. House music has influenced many other genres, including techno, trance, and hip-hop. Notable artists associated with Chicago House include Frankie Knuckles and Marshall Jefferson, who helped shape its distinctive sound.
