What is a Backdoor Dominant?

backdoor dominant is a chord progression used in jazz and related styles where a dominant seventh chord resolves to the tonic from a different direction than the traditional dominant. Instead of the typical V7 → I resolution, the backdoor dominant usually follows the pattern ♭VII7 → I.

For example, in the key of C major, the traditional dominant chord is G7, which resolves to C major. In a backdoor dominant progression, the chord B♭7 (the ♭VII7 chord) resolves to C major instead. This creates a smoother and more colorful resolution compared to the stronger pull of the traditional dominant.

Backdoor dominant progressions are commonly used in jazz, soul, R&B, and pop music. They often appear as iv7 → ♭VII7 → I progressions, which produce a warm, blues-influenced sound. Because the resolution feels softer and less predictable than a standard dominant resolution, the backdoor dominant adds subtle harmonic sophistication to a progression.
