What F♯7 is built from
Counting up in semitones from F♯:
| Note | Interval | Semitones from root |
|---|---|---|
| F♯ | root | 0 |
| A♯ | major third | 4 |
| C♯ | perfect fifth | 7 |
| E | 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 F♯7
All six strings are played. Lay your first finger flat across fret 2 and let the other fingers take the notes above it. Nothing is higher than fret 4, so it sits in first position.
All four strings are played. Nothing is higher than fret 4, so it sits in first position.
Play F♯, A♯, C♯ and E 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.

F♯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 F♯, A♯, C♯ and E, and not the same sounds written some other way.
Which keys F♯7 belongs to
| Key | Relative minor | Degree |
|---|---|---|
| B major | G♯ minor | V7 |
Each row is a key whose scale contains every note of F♯7. A major key and its relative minor use the same seven notes, so the chord belongs to both.
Chords that sit next to F♯7
The seven triads built on the scale of B major. These are the chords F♯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.
