E-shape barre, fret 5 5675xx
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.
What notes are in A Diminished?
The A Diminished chord has 3 different notes: A, C, E♭. Two minor thirds stacked; the diminished fifth (6 half steps above A) gives it its tension. 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 | Minor 3rd | 3 |
| E♭ | Diminished 5th | 6 |
