A leading-tone triad is a triad built on the seventh scale degree in a major key (vii in Roman numeral analysis), while a leading-tone seventh chord is a seventh chord built on the seventh scale degree (vii). Walter Piston considers and notates vii as V
7, an incomplete dominant seventh chord. (For the Roman numeral notation of these chords, see Roman numeral analysis.)

Major seventh in the context of Minor seventh
In music theory, a minor seventh is one of two musical intervals that span seven staff positions. It is minor because it is the smaller of the two sevenths, spanning ten semitones. The major seventh spans eleven. For example, the interval from A3 to G4 is a minor seventh, as the note G4 lies ten semitones above A3, and there are seven staff positions from A3 to G4. Diminished and augmented sevenths span the same number of staff positions, but consist of a different number of semitones (nine and twelve, respectively).

The harmonic minor scale (or Aeolian â™®7 scale) is a musical scale derived from the natural minor scale, with the minor seventh degree raised by one semitone to a major seventh, creating an augmented second between the sixth and seventh degrees.
Thus, a harmonic minor scale is represented by the following notation:
