What A minor is built from
Counting up in semitones from A:
| Note | Interval | Semitones from root |
|---|---|---|
| A | root | 0 |
| C | minor third | 3 |
| E | perfect fifth | 7 |
Move all three of those the same distance and you get the same chord on another root — that is what the minor triad formula 0 – 3 – 7 means.
How to play A minor
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 C, E and A strings ring open. Nothing is higher than fret 2, so it sits in first position.
Play A, C and E together. All three are white keys.
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.

A minor on the stave
The same three notes written on a treble stave, spelled the way a minor triad is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads A, C and E, and not the same sounds written some other way.
Which keys A minor belongs to
| Key | Relative minor | Degree |
|---|---|---|
| C major | A minor | vi |
| F major | D minor | iii |
| G major | E minor | ii |
Each row is a key whose scale contains every note of A minor. A major key and its relative minor use the same seven notes, so the chord belongs to both.
Chords that sit next to A minor
The seven triads built on the scale of C major. These are the chords A minor is most often played alongside, because they are made from the same seven notes. The small numeral is the degree each one stands on.
Other chords on A
Same root, different notes above it.
A major is its parallel: same root, same fifth, and only the third between them.
