Arpeggio quality

sus4

The suspended fourth chord replaces the third with the fourth, creating a root, a perfect fourth and a perfect fifth. The fourth sits directly above the fifth and wants to fall a half-step to the third, so the chord sounds like a question waiting for its answer. Rock, gospel and pop use it to delay resolution; jazz uses it to soften a dominant. Because there is no third, the quality is neither bright nor dark, which makes it a neutral bridge between major and minor. Arpeggiated, it trains the ear to hear the pull of a suspended note. Listen for the moment the fourth finally resolves.
