The $\mathrm{V^7}$ contains two tendency tones: its third and its seventh. As shown in **Example 1**, the third resolves upward by a half step to the root of the tonic chord ([[ti → do]]) while the seventh resolves downward by step to the third of the tonic chord ([[fa → mi (me)]]). When both tendency tones resolve as expected, this is known as a **strict resolution of the $\mathrm{V^7}$**. In a strict resolution of the progression $\mathrm{V^7–I}$, one must omit the fifth of either the $\mathrm{I}$ or the $\mathrm{V^7}$ in order to avoid consecutive perfect consonances between voices (e.g., [[parallel fifths]] or [[fifths by contrary motion]]). **Example 1.** Strict resolution of $\mathrm{V^7}$; incomplete $\mathrm{I}$. ![[example strict resolution of the V7 incomplete I.png]] ![[example strict resolution of the V7 incomplete I.mp3]] **Example 2.** Strict resolution of $\mathrm{V^7}$; incomplete $\mathrm{V^7}$. ![[example strict resolution of the V7 incomplete V7.png]] ![[example strict resolution of the V7 incomplete V7.mp3]]
