C6/9

— About this chord

C6/9 (1-3-5-6-9) blends the sweet, unresolved lift of a 6th with the bright color of a 9th, giving a lush, jazzy warmth without any dominant tension — it never needs to resolve. A signature bossa-nova and jazz comping chord, it's often used as a satisfying substitute for a plain major or major7 tonic chord, adding sophistication to endings and gentle vamps. On guitar the classic movable grip sits with the root on the A string and is easy to slide anywhere on the neck. Common as a final tonic chord in jazz standards and bossa nova tunes, giving a warm, floating resolution. Also searched as C6add9 or C sixth-ninth.
