What A♭7 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♭ | minor seventh | 10 |
Move all four of those the same distance and you get the same chord on another root — that is what the dominant seventh formula 0 – 4 – 7 – 10 means.
How to play A♭7
All six strings are played. Lay your first finger flat across fret 4 and let the other fingers take the notes above it. The shape runs from fret 4 to fret 6.
All four strings are played. Nothing is higher than fret 3, so it sits in first position.
Play A♭, C, E♭ and G♭ together. That is one white key and three 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.

A♭7 on the stave
The same four notes written on a treble stave, spelled the way a dominant 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 A♭7 belongs to
| Key | Relative minor | Degree |
|---|---|---|
| D♭ major | B♭ minor | V7 |
Each row is a key whose scale contains every note of A♭7. A major key and its relative minor use the same seven notes, so the chord belongs to both.
Chords that sit next to A♭7
The seven triads built on the scale of D♭ major. These are the chords A♭7 is most often played alongside, because they are made from the same seven notes. The small numeral is the degree each one stands on.
