What Amaj7 is built from
Counting up in semitones from A:
| Note | Interval | Semitones from root |
|---|---|---|
| A | root | 0 |
| C♯ | major third | 4 |
| E | perfect fifth | 7 |
| G♯ | major seventh | 11 |
Move all four of those the same distance and you get the same chord on another root — that is what the major seventh formula 0 – 4 – 7 – 11 means.
How to play Amaj7
Leave the low E string out. The A and top E strings ring open. Nothing is higher than fret 2, so it sits in first position.
All four strings are played. The E and A strings ring open. Nothing is higher than fret 1, so it sits in first position.
Play A, C♯, E and G♯ together. That is two white keys and two black.
Numbers in the grids are frets. Where a number is printed beside a grid, that is the fret the top row stands for; otherwise the thick bar at the top is the nut. A circle above a string means play it open, a cross means leave it out.

Amaj7 on the stave
The same four notes written on a treble stave, spelled the way a major seventh is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads A, C♯, E and G♯, and not the same sounds written some other way.
Which keys Amaj7 belongs to
| Key | Relative minor | Degree |
|---|---|---|
| E major | C♯ minor | IVmaj7 |
| A major | F♯ minor | Imaj7 |
Each row is a key whose scale contains every note of Amaj7. A major key and its relative minor use the same seven notes, so the chord belongs to both.
