How to play A Augmented on guitar
The A Augmented chord (Aaug) is made of A, C♯, E♯ - 1 3 #5. On a guitar in standard tuning the easiest way to play it is the open shape x03221, with no barre. Below are 3 shapes in all, from the lowest on the neck to the highest; the same chord sounds brighter the higher you play it.
E-shape, fret 5 5x766x
A-shape, fret 10 x(12)(11)(10)(10)x
Strings from the low E (left) to the high E (right). Numbers are fingers: 1 index, 2 middle, 3 ring, 4 little. x = do not play the string, o = open string, a bar = one finger across several strings.
Notes
What notes are in A Augmented?
The A Augmented chord has 3 different notes: A, C♯, E♯. Two major thirds stacked; the raised fifth makes it restless. A guitar chord rarely has as many strings as notes, so shapes double some of them: every shape here leaves at least one string unplayed - watch the x marks. Mute the strings marked x with the side of a fretting finger, so that only the chord rings.
| Note | Interval from the root | Half steps |
|---|---|---|
| A | Root | 0 |
| C♯ | Major 3rd | 4 |
| E♯ | Augmented 5th | 8 |
