D sharp Minor flat sixth major seventh

The minor flat sixth major seventh chord combines a minor third, a lowered sixth, and a major seventh (1-♭3-♭6-7 as a conceptual skeleton—fifth may be omitted or implied). The lowered sixth and major seventh create a dramatic contradiction: minor darkness below with a bright major-seventh ceiling. It is rare in common-practice diatonic harmony and appears more as a composed color in jazz, film, and modern classical-influenced writing.

Construction

Core tones emphasize ♭6 and 7 against ♭3; voicings vary widely.

Usage

Short dramatic hits, modal mixture colors, and cinematic harmony.

Examples

• Film scoring for uneasy beauty
• Modern jazz voicings on tonic minor with borrowed upper extensions
• Experimental pop production for one-bar shifts

Play

Separate ♭6 and 7 registrally; omit the fifth to reduce cluster density.

Ear-training cues

Minor third with both ♭6 and major seventh present in the harmony.
