The Dbmaj7 chord contains D♭, F, A♭ and C. Also written D♭maj7, it adds a major seventh to D♭ major. Compare root position and three inversions on the keyboard.
Build the Dbmaj7 chord by adding C natural to D♭–F–A♭. Its formula is 1–3–5–7: the third F is major, the fifth A♭ perfect and the seventh C major. D♭ and the C above it are eleven semitones apart.
Preserve the written chord spelling shown here; keyboard equivalence does not rename the chord.
Choose a position to keep the four written notes, sounding keys, bass note, playback and print reference synchronized.
Build the Dbmaj7 chord with D♭, F, A♭ and C. Choosing the B pitch class for C♭ would instead give Db7. This exercise checks note names as pitch classes, without prescribing a register or measuring live playing.
D♭maj7 uses 1–3–5–7: D♭–F–A♭–C.
a major triad plus a major seventh
Compared with D♭ major, add the major seventh above the root.
A seventh chord has four chord tones and therefore four positions: root position plus three inversions. The slash symbol identifies the written bass note.
| Position | Symbol | Notes, low to high | Bass |
|---|---|---|---|
| Root position, current selection | D♭maj7 | D♭4–F4–A♭4–C5 | D♭4 |
| First inversion | D♭maj7/F | F4–A♭4–C5–D♭5 | F4 |
| Second inversion | D♭maj7/A♭ | A♭4–C5–D♭5–F5 | A♭4 |
| Third inversion | D♭maj7/C | C5–D♭5–F5–A♭5 | C5 |
The Dbmaj7 chord diagrams give pitches and octaves rather than finger numbers. F, A♭ and C begin the three inversions. Read the bass label before comparing note order; each position contains the same complete four-note collection.
Use the written notes, keyboard positions and playback without treating the diagram as a required hand shape.

Scope: Supports theory and spelling only; keyboard layouts are PianoGrid examples, and no fingering is assigned.
D♭, F, A♭ and C: root, major third, perfect fifth and major seventh. F and C are natural notes.
The Dbmaj7 chord uses C natural as its major seventh. Db7 uses C♭, a minor seventh, sounding on B. Both retain D♭, F and A♭.
The Dbmaj7 chord has F and C. Dbm7 lowers them to F♭ and C♭. That changes both the third and seventh while retaining D♭ and A♭.
F identifies the first inversion, A♭ the second and C the third. Root position has D♭ lowest. The selector updates the notes, keyboard, bass label and playback together.
Select the four pitch classes that make D♭maj7, then check your answer.
This one-octave exercise checks the exact four-note pitch-class set. Order and inversion do not affect the result; missing and extra notes are reported, while fingering and live performance are not assessed.
