About C69 — 9th in bass
C69 is C, E, G, A and D — C6 with the ninth added as well.
It sounds wide and entirely at rest. The modern way to voice a tonic when a triad is too bare and a maj7 too pointed.
C69 notes and formula
| C | E | G | A | D |
|---|---|---|---|---|
| 1 | 3 | 5 | 6 | 9 |
Tonic — it commits to nothing.
Also written C6/9, C6add9 or C six nine. The same chord either way; which spelling you meet depends on who wrote the chart.
How to play C69
C69 in 9th in bass puts D in the bass instead of C, the 9th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
One of C69’s 9 common shapes does this: x55555.
Start with x30055 — no barre and 2 open strings. 1 of the 9 shapes here sits in open position. 7 of the 9 need a barre. Together they cover the neck from the 2nd fret to the 15th.
