Short answer

Dominant eleventh chords sound wide and suspended. The eleventh sits a half step above the major third that would normally anchor the chord, a clash sharp enough that the third is left out entirely and the fifth, seventh, ninth and eleventh do the talking.

How to use the A♭11 chord

The A♭11 chord is built from a root, a perfect fifth, a minor seventh, a major ninth and a perfect eleventh. Start at the root A♭ and stack the intervals to get the whole chord: A♭, E♭, G♭, B♭ and D♭. The same formula gives you the chord in any other key.

Dominant eleventh chords show up in modal jazz and gospel as a suspended, unresolved colour, often standing in for a sus4 with extra shimmer on top. They work best in slow-moving vamps rather than fast cadences.

How A♭11 differs from similar chords

A♭11 stacks a ninth and an eleventh on A♭7, and the eleventh is the same note as the fourth. Because that fourth clashes with the major third, the third is left out, so the chord sounds close to A♭7sus4 with a ninth. It differs from A♭13, which keeps the third and adds the sixth an octave up.

Where A♭11 is used

A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.

A♭11 is the chord that wants to resolve, so ending the loop on it hands straight back to the top.
