Deep house was largely pioneered by Chicago producers such as Marshall Jefferson (On The House) and Larry Heard (Mr. Fingers) and with tracks such as "Mystery of Love" (1985) and "Can You Feel It?" and (1986);[1] the latter had a similar impact on deep house as Derrick May's "Strings Of Life" (1987) did on Detroit techno.[2] Heard's deep house sound moved house music away from its posthuman tendencies back towards the lush soulful sound of early disco music (particularly that of old Philadelphia International and Salsoul records).[3]

Later period deep house tracks (1993—94) were more heavily influenced by disco and even merged into a disputable disco house genre.[citation needed] Modern deep house (post-2000) often shares features with the related genre of tech house but tends to focus on musical complexity where tech house focuses on simplicity.[citation needed]

House music is a genre of electronic dance music that originated in the American city of Chicago in the early 1980s. It was initially popularized circa 1984 in Chicago, but beginning in 1985, it fanned out to other major cities such as Baltimore, Detroit, Toronto, Mexico City, New York City, San Francisco, Boston, Montreal, Cancún, Manchester,[1] Miami, London,[1] and Paris. It then began to influence popular music in Europe, with songs such as "House Nation" by House Master Boyz and the Rude Boy of House (1987) and "Doctorin' the House" by Coldcut (1988) in the pop charts. Since the early to mid-1990s, house music has been infused in mainstream pop and dance music worldwide.

Early house music was generally dance-based music characterized by repetitive 4/4 beats, rhythms mainly provided by drum machines,[2] off-beat hi-hat cymbals, and synthesized basslines. While house displayed several characteristics similar to disco music, it was more electronic and minimalistic,[2] and the repetitive rhythm of house was more important than the song itself. House music today, while keeping several of these core elements, notably the prominent kick drum on every beat, varies a lot in style and influence, ranging from the soulful and atmospheric deep house to the more minimalistic microhouse. House music has also fused with several other genres creating fusion subgenres,[2] such as euro house, tech house, and electro house.

Many local Chicago house music artists suddenly found themselves with major label deals. House music proved to be a commercially successful genre and a more mainstream pop-based variation grew increasingly popular. Artists and groups such as Madonna,[2] Janet Jackson,[3] Björk, Kanye West,[4] and C+C Music Factory[2] incorporated the genre into their work. After enjoying significant success in the early to mid-90s, house music grew even larger during the second wave of progressive house (1999–2001). The genre has remained popular and fused into other popular subgenres, as the DJ Mag Top 100 DJs poll has been dominated by house DJs since the beginning of the polls. Today, house music remains popular in both clubs and in the mainstream pop scene while retaining a strong foothold on underground scenes across the globe.
