Notes and intervals of A♭m
Each note of A♭m has a job. Counted from the root, you get root (A♭), minor 3rd (C♭) and perfect 5th (E♭). Change one of these intervals and you get a different chord, which is why the formula 1 ♭3 5 is worth memorising rather than the shape alone.
| Degree | Interval | Note |
|---|---|---|
| 1 | root | A♭ |
| ♭3 | minor 3rd | C♭ |
| 5 | perfect 5th | E♭ |
How to play A♭m on guitar
Start with the first diagram: 4 6 6 4 4 4, read from the 6th string (low E) to the 1st string (high E), starting at fret 4. Your lowest note is A♭. The next positions give the same notes in a different order, which is useful when you want A♭m to sit closer to the surrounding chords.
This is a barre or movable shape: keep your index finger straight and close to the fret, and press with the side of the finger rather than the flat pad.

A♭m appears naturally in 3 major keys: B major (vi), G flat major (ii) and E major (iii). In B major it is the vi chord, so you will meet it in many songs written in that key and in its relative minor.

About minor chords
The minor chord swaps the major third for a minor third: 1 ♭3 5. That single semitone makes the sound darker, softer and more inward. Minor does not have to mean sad: in funk, Latin music or rock it can sound tough or cool, and it can end a piece just as convincingly as a major chord.
It is the tonic of minor keys (i) and appears on ii, iii and vi in major keys. Typical moves: i iv V (the major V borrowed from harmonic minor), i ♭VI ♭VII, and vi IV I V. Every major chord has a relative minor a minor third below that shares two of its notes.
Start with the open shapes Em, Am and Dm. The movable shapes grow out of them: the E-shape minor barre (root on the 6th string) and the A-shape minor barre (root on the 5th string). Compared with the major barre, only the third moves, one fret lower, so switching between major and minor is quick once your barre is solid.
Reading the symbol wrong is common: 'm' or '-' means minor, while 'M' or 'maj' means major, so Am and AM are different chords. On guitar, the minor third often lies on a string that is easy to mute in a barre. And m is not m7: the 7 adds a fourth note, the minor seventh.
