Secondary supertonic chord

File:Secondary supertonic chord.png

Secondary supertonic chord: ii⁷/V - V/V [- V] in C major (a7 - D7 [- G]) .

In music theory, the secondary supertonic chord or secondary second, is a secondary chord, but rather than being on the dominant it is on the supertonic scale degree and rather than tonicizing a degree other than the tonic, as does a secondary dominant, it creates a temporary dominant. Thus the progression $\frac{ii}{V}$ - $\frac{V}{V}$ - $\frac{V}{(I)}$.

Examples include ii7/III (F♯min.7, in C major).
