A close-position chord with the second voice from the top lowered an octave. Sits on four adjacent strings.
C#m69 is C#, E, G#, A# and D# — C#m6 with the ninth added as well.
It sounds cool and entirely at rest. No seventh, so nothing leans: a common last chord of a minor tune.

| C# | E | G# | A# | D# |
|---|---|---|---|---|
| 1 | ♭3 | 5 | 6 | 9 |
Minor tonic — nothing in it is pulling.
Also written C#m6/9, C#min6/9 or C#-6/9. The same chord either way; which spelling you meet depends on who wrote the chart.
Take the four notes stacked as close together as they go, then drop the second voice from the top an octave. The gap it opens is what makes the chord sound like a chord rather than a cluster.
It lands on four adjacent strings, which is why it is the workhorse voicing on guitar.
C#m69 has 13 of them, on the top four strings, the middle four strings and the bottom four strings, from open position up to the 12th — every inversion the chord has: C# in the bass, E in the bass, A# in the bass and D# in the bass. The one to learn first is the D# shape at the nut, which is the easiest grip here.
5 of them sit on the top four strings, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with x41320 — no barre and 1 open string. 1 of the 9 shapes here sits in open position. 5 of the 9 need a barre. Together they cover the neck from the 1st fret to the 13th.

The same notes rebuilt from scratch give 3 shell, 9 drop 3 and 12 rootless voicings, each on its own page.
Tensions. A shell of C#m69, root, third and seventh, leaves a string free, and the tones that belong over it are the 11 (F#).
