About A6 — drop 3 voicings
A6 is A, C#, E and F# — A with a major sixth added on top.
It sounds warm, and finished without being sweet. It closes a tune as firmly as the triad does but without the maj7’s shine, which is why so many standards end on one.

How to play A6
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
A6 has 9 of them, on strings 5-3-2-1 and strings 6-4-3-2, from the 2nd fret up to the 14th — every inversion the chord has: A in the bass, C# in the bass, E in the bass and F# in the bass. The one to learn first is the C# shape at the 2nd fret.
5 of them sit on strings 6-4-3-2, 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 5x465x — no barre and low, at the 4th fret. 1 of the 10 shapes here sits in open position. 5 of the 10 need a barre. Together they cover the neck from the 2nd fret to the 14th.
