Frequently asked
Which notes make a suspended fourth chord?
Root, perfect fourth and perfect fifth — for example C, F and G. There is no third.
Why does it sound unresolved?
Without a third it is neither major nor minor. The fourth hangs, waiting to fall to the third.
Where does it turn up?
Immediately before a resolution, most often over the tonic.
