Second chord |

Third inversion of the seventh chord; is formed by moving the prima, thirds and fifths of the seventh chord up an octave. The bottom sound of the second chord is the seventh (top) of the seventh chord. The interval between seventh and prima is a second (hence the name). The most common dominant second chord is denoted by V² or D², resolves into a tonic sixth chord (T⁶).

The subdominant second chord, or second chord of the second degree, is denoted by S² or II², resolves into a dominant sixth chord (V⁶) or a dominant quintsextachord (V^6/5), and also (in the form of an auxiliary chord) into a tonic triad. See Chord, Chord inversion.
