The F sharp major 7 chord contains F♯, A♯, C♯ and E♯. Also written F♯maj7, it combines a major triad with a major seventh. E♯ sounds on the F key of the piano.
Build the F sharp major 7 chord from F♯–A♯–C♯ and add E♯, eleven semitones above the root. Its formula is 1–3–5–7. F♯7 instead uses E natural, a minor seventh. Preserve E♯ in the notation even though its piano key is labeled F.
This spelling includes E♯. Preserve the theoretical written spelling even when an enharmonic name shares the same piano key.
Choose a position to keep the four written notes, sounding keys, bass note, playback and print reference synchronized.
Choose F♯, A♯, C♯ and the F pitch class in the exercise: F is the sounding key for written E♯. E natural would give the dominant seventh instead. Click order does not change the pitch-class result; use the selector to hear different bass notes.
F♯maj7 uses 1–3–5–7: F♯–A♯–C♯–E♯.
a major triad plus a major seventh
Compared with F♯ 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 | F♯maj7 | F♯3–A♯3–C♯4–E♯4 | F♯3 |
| First inversion | F♯maj7/A♯ | A♯3–C♯4–E♯4–F♯4 | A♯3 |
| Second inversion | F♯maj7/C♯ | C♯4–E♯4–F♯4–A♯4 | C♯4 |
| Third inversion | F♯maj7/E♯ | E♯4–F♯4–A♯4–C♯5 | E♯4 |
The F sharp major 7 chord diagrams mark the sounding keys while retaining E♯ as the written seventh. Three inversions begin on A♯, C♯ and E♯. These are pitch references without prescribed fingers; read the octave labels before trying a position.
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.
F♯, A♯, C♯ and E♯. The major third is A♯, the perfect fifth is C♯ and the major seventh is E♯.
The seventh above a root spelled F must use the letter E. E♯ preserves that relationship; F is the label of the same sounding piano key in this reference.
F♯maj7 uses E♯, the major seventh. F♯7 uses E natural, the minor seventh. Both retain F♯, A♯ and C♯.
A♯, C♯ and E♯ begin the first, second and third inversions. Root position begins on F♯. The written spelling stays consistent when the lowest note changes.
Select the four pitch classes that make F♯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.
