The ♭7 of F♯ is E
The ♭7 (flat seven, written b7) of F♯ (F sharp, F#) is E: a minor seventh above the root.
F♯ — the root, 1E — the ♭7
How to find it
Count letters first, the root included: F, G, A, B, C, D, E. A 7th lands on E.
Then the sound: a minor seventh is 10 semitones above F♯, which is exactly where E is — no sharp or flat needed.
Where you meet it
