Deep house is a subgenre of house music that originated in the 1980s, initially fusing elements of Chicago house with 1980s jazz-funk and touches of soul music. Its origins are attributed to Larry Heard’s track “Mystery of Love” in 1984.
Deep house is known for tempos typically from 110 to 125 BPM, muted basslines, spacious use of percussion elements (typically using a Roland TR-909 drum machine), soft keyboard sounds (pads), use of advanced chord structures, ambient mixes, and soulful, predominantly female vocals. Lyrics usually focus on positive/uplifting or forlorn modern blues lyrics. The use of vocals persisted in deep house as new forms of house music often abandoned them, but as of 2019, this difference has largely disappeared.
