A Dominant 7 guitar chord: five CAGED shapes
A dominant seventh chord combines a major triad with a flattened 7th. Its major 3rd and minor 7th create the tension that drives functional resolution and blues harmony.
Chord construction and function
The 3rd and ♭7 are the guide tones. Their tritone determines the chord’s pull even when roots or 5ths are omitted from a practical voicing.
