The Bmaj7 chord contains B, D♯, F♯ and A♯. It combines a B major triad with a major seventh. Locate all four notes on the keyboard, then compare root position and three inversions.
Build the Bmaj7 chord with degrees 1–3–5–7. A♯ is the major seventh, eleven semitones above B. B7 uses A natural instead; the root, third and fifth remain B, D♯ and F♯.
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 Bmaj7 chord by selecting B, D♯, F♯ and A♯ in the exercise. If A natural is selected instead, remove it and choose A♯. This check assesses the pitch-class set, not live playing or fingering.
Bmaj7 uses 1–3–5–7: B–D♯–F♯–A♯.
a major triad plus a major seventh
Compared with B 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 | Bmaj7 | B3–D♯4–F♯4–A♯4 | B3 |
| First inversion | Bmaj7/D♯ | D♯4–F♯4–A♯4–B4 | D♯4 |
| Second inversion | Bmaj7/F♯ | F♯4–A♯4–B4–D♯5 | F♯4 |
| Third inversion | Bmaj7/A♯ | A♯4–B4–D♯5–F♯5 | A♯4 |
The Bmaj7 chord diagrams show keys and note order rather than prescribed fingers. Inversions keep all four chord tones while changing the bass. Select a position to compare its keyboard, written notes and printable view before choosing a hand position.
Use the written notes, keyboard positions and playback without treating the diagram as a required hand shape.

B, D♯, F♯ and A♯. The formula 1–3–5–7 includes a major seventh, rather than the lowered seventh used by a dominant seventh chord.
No. The Bmaj7 chord contains A♯; B7 contains A natural. Compare the seventh while leaving B, D♯ and F♯ unchanged.
No. A Bmaj7 chord has B as its root. B♭maj7 starts a semitone lower and contains B♭, D, F and A. The flat changes the root, not the chord quality.
Read the bass: D♯ indicates the first inversion, F♯ the second and A♯ the third. Root position has B lowest. All four notes remain in every displayed position.
Select the four pitch classes that make Bmaj7, 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.
One octave, C through B. Select a key again to remove it.
