Why it sounds like that

D augmented major 7th is built from the formula 1, 3, ♯5, 7. The augmented 5th, A♯, is what separates it from the D major 7th, where the 5th is A natural. The major 3rd and major 7th remain unchanged.

What goes wrong with D augmented major 7th?

  • Letting the low E string ring instead of muting it.
  • Letting the A string ring instead of muting it.
  • Fretting the G string with the pinky instead of the ring finger, causing the note to go sharp.

When to use it

D augmented major 7th works as a substitute for D major 7th when the melody moves to the ♯5. It fits jazz ballads and passages that need a brighter, more restless major sound.

Changing to and from D augmented major 7th

  • Sliding the shape down two frets to the 5th fret gives C augmented major 7th.
  • Sliding the shape up one fret to the 8th fret gives E♭ augmented major 7th.

Which voicing to use

The open voicing keeps D in the bass and is easiest to reach. The F♯ inversion starting on the 1st fret puts the major 3rd in the bass and gives a tighter, higher register.
