Chord Shapes

Dominant 7th Suspended 4th

Intervals: 1-4-5-b7 (often with added 9). A dominant 7th where the 3rd is replaced by the 4th, creating a strong tendency for the 4th to resolve down by semitone to the 3rd. In jazz and gospel harmony V7sus4 frequently resolves to V7 then to I, giving a powerful “held breath then release” effect. In rock and pop, 7sus4 shapes can sit on I or V for long stretches as part of a riff or strumming pattern. On guitar, typical voicings keep the 4th high in the chord so that its resolution is clearly audible. Use it to delay the arrival of the dominant 3rd while still signalling dominant function through the b7 and upper extensions.
