D#6/9 Chord

What is the D#6/9 Chord?

If you're learning the D#6/9 chord, the fastest path is understanding the chord tones—not just memorizing one shape. This chord is enharmonically equivalent to Eb6/9.

Notes and Arpeggios

The 6/9 chord stacks a major 6th and a 9th on a major triad, producing a warm, complete sound that feels settled but colorful. It's a classic jazz voicing often used as a final chord or a substitute for plain major. The chord tones are: D#, F##, A#, B#, E#. It's built from degrees 1, 3, 5, 6, and 9.

How to Use It

Extended voicings are a staple of jazz, neo-soul, and modern pop harmony. On guitar, start with the chord-box voicings, then find at least two different string sets where the same chord tones appear.

Move the shape to a few different frets while keeping the same interval structure in mind. Use the highlights to spot where the same tone repeats across strings.
