Deep house's characteristic harmonic sound comes from jazz-influenced minor7 and major7 chords rather than simpler triads

Deep house is distinguished from other house subgenres by its use of 7th chords — specifically minor 7 and major 7 voicings drawn from jazz harmony. Where tech house, techno, and harder house styles use minimal harmony (or none), deep house tracks typically feature chord progressions where the 7th is always present, giving the music a warm, complex, ‘unresolved’ quality. This harmonic language links deep house to gospel, jazz, and soul, and to artists like Larry Heard, Masters at Work, and Kerri Chandler who drew on these traditions. The presence of the 7th is what makes a chord ‘feel’ deep house rather than pop or rock; the same notes without the 7th produce a thinner, more neutral sound.

Examples

F major 7 + E minor 7 = basic deep house two-chord loop. F minor 7 + Ab major 7 + C minor 7 = the Masters at Work ‘To Be In Love’ chord sequence. A minor 7 + E minor 7 + D minor 7 = common all-minor deep house progression.

Assessment

Play a C minor triad (C-Eb-G) and then a C minor 7 chord (C-Eb-G-Bb); describe the difference in harmonic colour and explain why the minor 7 version is more associated with deep house.
