Ab Dominant 7th Guitar Chord (Ab7)

The Ab Dominant 7th chord (Ab7) is built from the notes Ab, C, Eb, and Gb: the R, 3, 5, b7 of Ab. Below are the five ways to play Ab7 on guitar, laid out in order from the lowest position on the neck to the highest.

A dominant seventh chord is bluesy and restless: it wants to resolve, which is why it drives blues, funk, and the V chord in nearly every key. The lowest shape starts around fret 1, and Ab7 appears in four more positions higher up the neck.
