D 11th Chord

– – – – –

Formula R – 9 – 3 – 11 – 5 – ♭7

Summary

D 11th is built from the notes D, E, G♭, G, A, C. The interval from D to E is a major 2nd (2 semitones), from D to G♭ is a major 3rd (4 semitones), from D to G is a perfect 4th (5 semitones), from D to A is a perfect 5th (7 semitones), from D to C is a minor 7th (10 semitones). This chord contains 1 flatted note.

The 11th chord is a massive, harmonically rich dominant extension. In practice, the major 3rd is almost always dropped because it clashes with the 11th — making it sound and play a lot like a 9sus4. It's a big, open, soulful chord.

Theory

The theoretical formula is R, 3, 5, ♭7, 9, 11, but the perfect 11th creates a harsh clash against the major 3rd. So in practice, the 3rd is omitted, leaving R, 5, ♭7, 9, 11 — which is functionally a 7sus4 with an added 9th. This gives the chord its characteristic open, ambiguous quality.

On the guitar

On guitar, think of it as a 9sus4 voicing — play a 7sus4 shape and add the 9th where possible. The 5th and sometimes even the root can be dropped if a bassist is covering it. These voicings tend to use stacked fourths, which sit naturally under the fingers on adjacent strings.

Advanced

The dominant 11th is a staple of soul and jazz arranging. Its open, spacious sound makes it perfect for sustained pads and vamps. In modal jazz, 11th-type voicings can sustain entire sections without resolving, creating a floating, atmospheric feel.
