Key of F Sharp Minor
The key of F Sharp Minor has three sharps (F♯, C♯, G♯). Its notes are F♯ G♯ A B C♯ D E, and the seven chords built on those notes are F♯m, G♯dim, A, Bm, C♯m, D, E.
That short list is most of what you need. Learn the scale, learn those seven chords, and you can read, accompany or improvise almost anything written in F Sharp Minor without stopping to work out what fits. The relative major, A Major, uses the same key signature and the same seven notes, so learning one gets you both.
Everything below is spelled out: the signature, each degree of the scale, the triads and sevenths with their roman numerals, the progressions those chords make, and a practice order that gets the key under your hands rather than into your notebook. Three of the chords have a keyboard you can play right on this page.
F Sharp Minor Key Signature
F Sharp Minor is written with three sharps (F♯, C♯, G♯). They always appear in this order on the staff, and they apply to every octave, not just the one where the symbol sits.
| Order | Note | What it means |
|---|---|---|
| 1 | F♯ | every F is played a semitone higher |
| 2 | C♯ | every C is played a semitone higher |
| 3 | G♯ | every G is played a semitone higher |
The order never changes. Sharps are added F♯ C♯ G♯ D♯ A♯ E♯ B♯, and a key signature is always the first 3 of that list.
A quick check while you are reading: if a passage in F Sharp Minor has an accidental that is not in the signature, it is telling you something — usually a borrowed chord or a temporary move to a nearby key. Those are the notes worth marking in pencil.
Notes And Scale Degrees In F Sharp Minor
Each note of the F Sharp Minor scale has a job. The names below are the ones teachers and theory books use, and knowing them is what lets you talk about music in any key at once.
| Degree | Note | Name | Chord built on it |
|---|---|---|---|
| 1 (i) | F♯ | Tonic | F♯m |
| 2 (ii°) | G♯ | Supertonic | G♯dim |
| 3 (III) | A | Mediant | A |
| 4 (iv) | B | Subdominant | Bm |
| 5 (v) | C♯ | Dominant | C♯m |
| 6 (VI) | D | Submediant | D |
| 7 (VII) | E | Subtonic | E |
The tonic, F♯, is home. The dominant, C♯, is the note that most wants to go back there, which is why the v chord turns up at the end of so many phrases. The subdominant, B, is the gentler pull.
Play the scale slowly and say the numbers out loud as you go. It feels silly for about a week, and then you start hearing degrees instead of letters, which is the whole point.
Chords In F Sharp Minor
There are seven chords in F Sharp Minor, one on each note of the scale. Every one of them uses only notes from the key, which is why they sound like they belong together.
| Numeral | Chord | Notes | Quality |
|---|---|---|---|
| i | F♯m | F♯ A C♯ | Minor |
| ii° | G♯dim | G♯ B D | Diminished |
| III | A | A C♯ E | Major |
| iv | Bm | B D F♯ | Minor |
| v | C♯m | C♯ E G♯ | Minor |
| VI | D | D F♯ A | Major |
| VII | E | E G♯ B | Major |
Uppercase numerals are major chords, lowercase are minor, and the little circle marks the diminished one. That single diminished chord is the odd one out in every major and minor key, and beginners can safely leave it alone for a while.
Learn them in this order: F♯m, C♯m, Bm, then D. Those four carry an enormous amount of real music between them.
The I Chord F Sharp Minor

Tap the highlighted keys — any order.
F♯m — F♯, A, C♯. The i chord of F Sharp Minor.
This is home. Every phrase in the key is measured against it, and most of them end on it.
Play it on the keyboard above: right hand thumb on the root, then fingers 3 and 5 on the other two notes. Left hand is the mirror — finger 5 on the root, then 3 and 1. Press the three keys and the page will tell you whether you found them.
The Iv Chord B Minor

Bm — B, D, F♯. The iv chord of F Sharp Minor.
The subdominant lifts away from home without much tension. It is the chord that makes a progression feel like it is going somewhere pleasant.
Play it on the keyboard above: right hand thumb on the root, then fingers 3 and 5 on the other two notes. Left hand is the mirror — finger 5 on the root, then 3 and 1. Press the three keys and the page will tell you whether you found them.
The V Chord C Sharp Minor

Tap the highlighted keys — any order.
C♯m — C♯, E, G♯. The v chord of F Sharp Minor.
The dominant is the tension chord. It pulls back to the tonic hard enough that your ear finishes the phrase before your hands do.
Play it on the keyboard above: right hand thumb on the root, then fingers 3 and 5 on the other two notes. Left hand is the mirror — finger 5 on the root, then 3 and 1. Press the three keys and the page will tell you whether you found them.
Seventh Chords In F Sharp Minor
Add one more note — a third above the top of each triad — and the seven chords of F Sharp Minor become seventh chords. This is the sound of jazz, soul and most film music, and it is one finger away from what you already know.
| Numeral | Chord | Notes |
|---|---|---|
| i7 | F♯m7 | F♯ A C♯ E |
| ii°7 | G♯m7♭5 | G♯ B D F♯ |
| III7 | Amaj7 | A C♯ E G♯ |
| iv7 | Bm7 | B D F♯ A |
| v7 | C♯m7 | C♯ E G♯ B |
| VI7 | Dmaj7 | D F♯ A C♯ |
| VII7 | E7 | E G♯ B D |
The one to learn first is C♯m7, the dominant seventh. It is the strongest pull back to the tonic in tonal music, and once your ear knows it you will hear it coming at the end of almost every phrase.
You do not have to play all four notes. Dropping the fifth keeps the character and frees a finger, which is exactly what pianists do when the left hand is busy.
Chord Progressions In F Sharp Minor
Chords in F Sharp Minor are worth far more in sequence than alone. These four progressions use nothing outside the key, and between them they cover most of what you will meet.
| Progression | In this key | Why it works |
|---|---|---|
| i–VI–III–VII | F♯m – D – A – E | The minor-key version of the pop progression. |
| i–iv–v–i | F♯m – Bm – C♯m – F♯m | Home, away, tension, home — the minor cadence. |
| i–VII–VI–v | F♯m – E – D – C♯m | A descending line that appears in everything from folk to metal. |
| i–III–VII | F♯m – A – E | Two steps out and one strong step back. |
Play each one four times through, left hand roots and right hand triads, before you change anything. Then try the same progression with the right hand starting from an inversion, so your hand stops jumping around the keyboard — that one change is what makes chord playing sound like music instead of exercises.
Relative And Parallel Keys Of F Sharp Minor
A Major is the relative major of F Sharp Minor. Same key signature, same seven notes, different home note — so it is the same white-and-black-key geography with the gravity moved. If you can play one scale you can already play the other.
F Sharp Major is the parallel key: same starting note, different signature. That is the one beginners mix up. Relative keys share notes; parallel keys share a home. Composers switch between parallel keys when they want the mood to change without the music going anywhere.
Next door on the circle of fifths sit B Minor and C Sharp Minor. Those keys differ from this one by a single accidental, which is why a piece can slip into one of them mid-phrase and back again without anything sounding forced.
How To Practice In F Sharp Minor
A week in F Sharp Minor, fifteen minutes a day, in this order:
- The scale, hands separately. Slowly enough that you never have to correct a note. Speed is the reward for accuracy, not the route to it.
- The tonic triad, F♯m, in all three positions. Root position, then first inversion, then second. Say which one you are playing.
- i – v – i. F♯m to C♯m and back, until your hand finds it without looking.
- Add Bm and D and play the four-chord progression above.
- Play something real in the key. A hymn, a pop song, a study — anything where the chords are doing a job rather than being practised.
If a step is not comfortable, stay on it. Nobody has ever regretted spending an extra day on step 2, and everybody who skipped it has gone back to it later.
