šµ A very common tension chord, replacing the third with a perfect fourth. It creates a strong feeling of anticipation and usually resolves to the dominant 7th or a major triad. Use it frequently as the V7sus4 before the V7 to I, or as a prominent chord in rock and pop for a yearning, unresolved sound that demands to move forward. Feels like holding your breath before a release.
