D6 Chord

D6 keeps the D major triad and adds B, its sixth. It can finish a phrase with more color than the plain triad without becoming a seventh chord.

Where does D6 belong?

The extra sixth belongs to the major scale and colors the chord without changing its major third.
Play the role cards to hear how its surrounding chords change the job it does; Diatonic Chords explains the basic numbered roles.

Progressions to try

  • GAD6

    After the approach chords, D6 lands on the tonic with an added sixth rather than a plain triad.

  • AD6EA

    The IV chord carries the sixth here; compare it with the unextended chords around it.

Which shape should you use?

On guitar, start with the open xx0202 grip. Let the open strings ring and keep any strings marked x silent. The x54475 shape gives you another position when the neighboring chords sit elsewhere on the neck.

On ukulele, start with 2222, played at the 2nd fret. The 7979 grip moves the chord to another register.

On piano, play D-F sharp-A-B. Move D up an octave to reach the first inversion, F sharp-A-B-D; the notes remain the same while the lowest voice changes.

What are the inversions?

D, F sharp and A make the major triad; B adds the sixth.

  • Root position: D-F sharp-A-B, with D lowest.
  • First inversion: F sharp-A-B-D, written D6/F# if F sharp is lowest in the whole arrangement.
  • Second inversion: A-B-D-F sharp, written D6/A if A is lowest in the whole arrangement.
  • Third inversion: B-D-F sharp-A, written D6/B if B is lowest in the whole arrangement.

A slash chord names the note in the bass, not merely the lowest note under one hand. Chord Inversions shows how to read that distinction.

How does D6 differ from D?

Remove only B and D6 becomes D. The major third stays, so this is an added note, not a replacement. Try that one-note change on piano, then use the comparer to hear it in the full chord. See D for the other chord's full spelling and roles.
