Which key has 7 sharps?
Two keys share every signature — one major, one minor. 7 sharps means C♯ major or its relative minor A♯ minor, and nothing else: the seven sharp keys and seven flat keys each use a different number of accidentals, so the count alone identifies the pair. The steps below show how to name it from the staff without memorising a table.
How to read it
- Count the sharps. Count the accidentals sitting between the clef and the time signature. Seven of them narrow it to one major key and one relative minor.
- Name the major key. The last sharp is B♯. Go up one semitone from it and you land on C♯ — the key.
- Name the relative minor. Count down three semitones from C♯ — or up six steps round the circle of fifths — to reach A♯ minor, which shares this signature.
- Check the melody. The signature alone cannot tell you which of the two the piece is in. Look at the first and last notes: C♯ major and A♯ minor use identical notes, so the music decides.
The order of sharps
Sharps never appear in an arbitrary order. They are added one at a time in the fixed sequence F♯ C♯ G♯ D♯ A♯ E♯ B♯, so a signature with 7 sharps always uses the first seven of them: F♯ C♯ G♯ D♯ A♯ E♯ B♯. That is why counting the accidentals is enough to name the key — you also know exactly which ones they will be.
7 sharps or 5 flats?
C♯ major (7 sharps) and D♭ major (5 flats) are enharmonic equivalents: on a keyboard they are the same pitches, written with different note names. Editors choose whichever spelling gives the performer fewer awkward accidentals to read.
