Explanation
A minor seventh is classified as a dissonance. In jazz and popular harmony, a seventh chord may function as a stable part of the texture, but this does not change the interval classification.

How the interval sounds

A minor seventh spans ten semitones and inverts to a major second. As the seventh of a dominant seventh chord, it normally resolves downward by step.

Famous example:

  • "Somewhere" from West Side Story

Tendencies & resolutions

The minor 7th tends to resolve — most often downward to a 6th (one note descends by a half step or whole step). In a dominant 7th chord (G7), the minor 7th (F) resolves down to the tonic's 3rd (E in C major). It can also resolve to the octave, rising by two semitones.

Harmonic context

A minor seventh appears in dominant, minor, and half-diminished seventh chords. b7 distinguishes Mixolydian from Ionian and belongs to the blues collection; in jazz, seventh chords commonly serve as the basic form of diatonic harmony.
