A69 guitar chord
An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.

How to play A69
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
A69 has 6 of them, on strings 6-5-4-3-2-1, strings 5-4-3-2-1, strings 6-4-3-2-1 and strings 6-5-4-3-2, from the 2nd fret up to the 6th — every inversion the chord has: A in the bass, E in the bass and B in the bass. The one to learn first is the A shape at the 2nd fret, which is the easiest grip here.
Start with x04422 — no barre and 1 open string. 1 of the 8 shapes here sits in open position. 6 of the 8 need a barre. Together they cover the neck from the 2nd fret to the 12th.

| xx7677 | 6th fret | A, root position | B | barred |
| x77677 | 6th fret | E, 2nd inversion | B | barred |
| x-9-9-9-10-9 | 9th fret | F#, 6th in the bass | C# | barred |
| x-12-9-11-10-9 | 9th fret | A, root position | C# | all fretted |
| x-12-11-11-12-12 | 11th fret | A, root position | E | barred |
