Open position first, then up the neck. Tap a shape to put it on the fretboard above and hear it. The numbers are fingers (1 is your index), × means leave that string out, and ○ means let it ring open.
What's in A
A major chord stacks a major 3rd (four half steps) and a perfect 5th (seven half steps) on the root. For A that gives A, C♯ and E. Every shape below is some arrangement of those three notes, with a few doubled in another octave.
| Note | Formula | Interval from A |
|---|---|---|
| A | 1 | Root |
| C♯ | 3 | Major 3rd |
| E | 5 | Perfect 5th |
Major chords sound settled and bright. They are the I, IV and V of every major key, which is why so many songs get by on three of them.
