For example, the interval from A 3 to G 4 is a minor seventh, as the note G 4 lies ten semitones above A 3, and there are seven staff positions from A 3 to G 4. Diminished and augmented sevenths span the same number of staff positions, but consist of a different number of semitones (nine and twelve, respectively).

Nondominant seventh chord resolution along a circle progression, the seventh resolves down by step to the third of the next chord: I 7 –IV [3] Play ⓘ. B resolves to A. In music theory, a nondominant seventh chord is both a diatonic chord and a seventh chord, but it does not possess dominant function, [2] and thus it is not a dominant ...
