What D♭maj7 is built from
Counting up in semitones from D♭:
| Note | Interval | Semitones from root |
|---|---|---|
| D♭ | root | 0 |
| F | major third | 4 |
| A♭ | perfect fifth | 7 |
| C | 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 D♭maj7
Leave the low E string out. 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 D♭, F, A♭ and C 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.

D♭maj7 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 D♭, F, A♭ and C, and not the same sounds written some other way.
Which keys D♭maj7 belongs to
| Key | Relative minor | Degree |
|---|---|---|
| D♭ major | B♭ minor | Imaj7 |
| A♭ major | F minor | IVmaj7 |
Each row is a key whose scale contains every note of D♭maj7. A major key and its relative minor use the same seven notes, so the chord belongs to both.
