D augmented chord on bass (Daug)

Also called or written Daug or D+

D augmented contains D, F♯, and A♯. The 3rd-fret shape stacks three notes across adjacent strings, so the left hand stays compact but the stretch is real.

Why it sounds like that

D augmented is built from the formula 1, 3, ♯5. The augmented 5th from D to A♯ gives the chord its tense, unresolved quality. Compare it with D major, which lowers that fifth to A natural.

What goes wrong with D augmented?

  • Letting the ring finger flatten onto the D string, which deadens the F♯.
  • Allowing the muted E string to ring, adding an extra note that changes the voicing.
  • Pressing the middle finger too far from the fret, causing the D string to buzz.

When to use it

D augmented works as a passing chord in D major, often moving to D major or D 5th. Its unstable sound suits rock, blues, and funk lines that need a brief lift before resolving.

Changing to and from D augmented

  • Move to D major by lowering the A♯ on the G string one fret to A natural while keeping the other fingers in place.
  • Slide the shape up one fret to the 4th fret to reach E♭ augmented.

Which voicing to use

The 3rd-fret position keeps D in the bass for a root-position sound. The Daug/F♯ inversion at the 1st fret puts F♯ on the bottom, which softens the chord's drive and works well when the bass line moves stepwise.

Common questions

How is D augmented written?

D augmented is written as D+ or Daug.

What is the difference between D augmented and D major?

D augmented raises the fifth from A to A♯. That single change makes the chord sound tense and unresolved, while D major sounds stable.

Can I play D augmented higher on the neck?

Yes, the 8th-fret position uses the same shape on the E, A, and D strings. It gives a brighter register but the same chord tones.
