Circle of Fifths Chart for Major Keys, Minor Keys and Chords
Find every common major key, relative minor, key signature, sharp and flat order, primary chord, neighboring key, and enharmonic spelling. Use the interactive explorer to build a correctly spelled major scale and its diatonic triads.
This chart follows common-practice Western major and minor tonality. It does not fully describe modes, chromatic harmony, microtonal systems, historical tunings, jazz substitutions, or non-Western pitch organization.
How do you use the circle of fifths?
Start at C major. Move clockwise to add sharps and move counterclockwise to add flats. The inner key at each position is the relative minor. The key immediately clockwise is the dominant, while the key immediately counterclockwise is the subdominant.
Open Music Theory’s major-key explanation places key signatures around the circle by accidental count. Each neighboring major key differs by one accidental, so adjacent scales share six of their seven notes.
Clockwise motion
Adds one sharp
C moves to G, then D, A, E, B, and F♯. Each step ascends by a perfect fifth.
Counterclockwise motion
Adds one flat
C moves to F, then B♭, E♭, A♭, D♭, and G♭. Each step descends by a perfect fifth.
Inner minor ring
Shares the signature
A relative minor uses the same key signature as its paired major key but centers a different tonic.
Neighboring keys
Share 6 of 7 notes
Adjacent major keys differ by one accidental, which makes them closely related for tonal movement.
Fast answers for reading the circle
These rules cover the standard major and natural-minor layout. Keep note spelling and musical context when you apply them to real notation.
What sits at the top of the circle?
C major and A minor sit at the top because their key signature has no sharps or flats.
Which direction adds sharps?
Clockwise movement adds one sharp at each step.
Which direction adds flats?
Counterclockwise movement adds one flat at each step.
What is one clockwise step from C?
G major is one perfect fifth clockwise from C major and has one sharp.
What is one counterclockwise step from C?
F major is one perfect fifth counterclockwise from C major and has one flat.
What is C major’s relative minor?
A minor is the relative minor of C major because both use no sharps or flats.
What is the order of sharps?
The order of sharps is F, C, G, D, A, E, B.
What is the order of flats?
The order of flats is B, E, A, D, G, C, F.
How does the circle show the V chord?
The clockwise neighbor of a major key is its dominant, or V, chord root.
How does the circle show the IV chord?
The counterclockwise neighbor of a major key is its subdominant, or IV, chord root.
Do relative keys share every scale note?
A major key and its natural relative minor share all seven key-signature notes.
Does a key signature prove the key?
No. Major and relative minor share one signature, so the music must reveal the tonic.
How the circle is organized
The outer ring shows major keys. The inner label shows each relative minor. The accidental count rises from zero to six in either direction before the sharp and flat spellings meet enharmonically.

| Clock position | Major key | Relative minor | Key signature | Relationship to C |
|---|---|---|---|---|
| 12 o’clock | C major | A minor | No sharps or flats — No accidentals | Reference point |
| 1 o’clock | G major | E minor | 1 sharp: F♯ | One perfect fifth clockwise |
| 2 o’clock | D major | B minor | 2 sharps: F♯, C♯ | Two perfect fifths clockwise |
| 3 o’clock | A major | F♯ minor | 3 sharps: F♯, C♯, G♯ | Three perfect fifths clockwise |
| 4 o’clock | E major | C♯ minor | 4 sharps: F♯, C♯, G♯, D♯ | Four perfect fifths clockwise |
| 5 o’clock | B major | G♯ minor | 5 sharps: F♯, C♯, G♯, D♯, A♯ | Five perfect fifths clockwise |
| 6 o’clock | F♯ major / G♭ major — Enharmonic spellings | D♯ minor / E♭ minor | 6 sharps / 6 flats | Enharmonic meeting point |
| 7 o’clock | D♭ major | B♭ minor | 5 flats: B♭, E♭, A♭, D♭, G♭ | Five perfect fifths counterclockwise |
| 8 o’clock | A♭ major | F minor | 4 flats: B♭, E♭, A♭, D♭ | Four perfect fifths counterclockwise |
| 9 o’clock | E♭ major | C minor | 3 flats: B♭, E♭, A♭ | Three perfect fifths counterclockwise |
| 10 o’clock | B♭ major | G minor | 2 flats: B♭, E♭ | Two perfect fifths counterclockwise |
| 11 o’clock | F major | D minor | 1 flat: B♭ | One perfect fifth counterclockwise |
A perfect fifth spans seven semitones; the written letter names must also span five staff positions.
- • The 6 o’clock position has two common spellings because F♯ and G♭ are enharmonic in twelve-tone equal temperament.
- • Relative major and minor keys use the same key signature but have different tonics.
- • This layout follows common-practice Western major and minor key signatures.

Read direction, accidental count, and tonic separately
Direction shows the interval relationship between keys. The accidental count shows the written key signature. The tonic shows which pitch acts as home. A key signature narrows the possibilities, but cadence, melody, bass, and harmonic function reveal whether the passage is major or relative minor.
1
Find the tonic
Identify the major or minor home pitch named by the music.
2
Check direction
Clockwise is sharper; counterclockwise is flatter.
3
Count accidentals
Each circle step changes the signature by one accidental.
4
Confirm context
Use cadences and harmonic emphasis rather than the signature alone.
Major Key Signatures from Seven Flats to Seven Sharps
The complete written key-signature system contains 15 major keys. The center key has no accidentals, seven keys use flats, and seven keys use sharps.

| C♯ major | 7 sharps | F♯, C♯, G♯, D♯, A♯, E♯, B♯ — Seven-sharp spelling | A♯ minor |
Sharp order: F–C–G–D–A–E–B. Flat order: B–E–A–D–G–C–F.
- • The order of sharps reverses to form the order of flats.
- • E♯, B♯, C♭, and F♭ are valid written notes when the key spelling requires them.
- • Enharmonic keys can sound alike on equal-tempered instruments while remaining different written keys.

Key-signature shortcuts work when spelling stays correct
For a sharp key, move one semitone above the final sharp to name the major tonic. For a flat key with at least two flats, the second-to-last flat names the major tonic. F major is the one-flat exception. The University of Puget Sound key-signature lesson uses the same clockwise-sharper and counterclockwise-flatter relationship.
How to Identify a Key Signature Quickly
Use the last sharp or the second-to-last flat to identify most major keys. Then find the relative minor three semitones below the major tonic while preserving correct note spelling.
Swipe horizontally inside the table to view every column.
| Situation | Rule | Example | Answer |
|---|---|---|---|
| No sharps or flats | The major key is C; the relative minor is A minor. | Empty key signature | C major or A minor |
| One sharp | Move one semitone above the last sharp. | Last sharp F♯ | G major |
| Three sharps | Move one semitone above the last sharp. | F♯, C♯, G♯ | A major |
| Six sharps | Move one semitone above the last sharp. | Last sharp E♯ | F♯ major |
| One flat | Memorize the special case. — One-flat exception | B♭ only | F major |
| Two flats | The second-to-last flat names the major key. | B♭, E♭ | B♭ major |
| Four flats | The second-to-last flat names the major key. | B♭, E♭, A♭, D♭ | A♭ major |
| Seven flats | The second-to-last flat names the major key. | Last two flats C♭, F♭ | C♭ major |
| Find relative minor | Move down three semitones from the major tonic. — Relative-minor rule | E♭ major → E♭–D–D♭–C | C minor |
| Find relative major | Move up three semitones from the minor tonic. | F♯ minor → F♯–G–G♯–A | A major |
A semitone is the smallest standard step in twelve-tone equal temperament; three semitones form a minor third.
- • A key signature alone does not prove whether a passage is in the major key or its relative minor; musical context identifies the tonic.
- • For flats, F major is the one-flat exception because there is no second-to-last flat.
- • Minor music may add raised scale degrees as accidentals without changing the written key signature.

The neighboring major keys reveal I, IV, and V
Place the home major key in the center. The counterclockwise neighbor supplies IV, and the clockwise neighbor supplies V. In C major, that gives F–C–G. This relationship identifies primary chord roots, but it does not choose inversions, seventh chords, extensions, rhythm, or voice leading.
I, IV and V Primary Chords by Major Key
For a major key, the tonic chord is I, the counterclockwise neighbor is IV, and the clockwise neighbor is V. These three major triads establish the key strongly.

| F♯ major | B major | F♯ major | C♯ major | Left neighbor · home · right neighbor |
| C♯ major | F♯ major | C♯ major | G♯ major — Theoretical dominant spelling | Theoretical next clockwise key |
Roman numerals identify scale-degree function: I is tonic, IV is subdominant, and V is dominant.
- • The circle supplies chord roots; chord quality still depends on the key and harmonic context.
- • In minor keys, iv is normally minor and the dominant may be altered to major by raising scale degree 7.
- • The theoretical G♯ major chord uses G♯–B♯–D♯ even though A♭ major is the more common enharmonic key.

Relative keys share a signature; nearby keys share six notes
A major key and its relative natural minor use the same seven pitch names and the same key signature. Adjacent major keys share six pitch names and change one note. The Open Music Theory minor-key chapter explains relative relationships and the minor-key circle. Harmonic and melodic minor often add raised scale degrees as local accidentals without changing the key signature.
Enharmonic keys can sound alike and still function differently
F♯ major and G♭ major use the same equal-tempered piano keys, yet their scales use different note names. Spelling preserves scale structure, chord function, voice leading, and modulation direction. The clearer spelling depends on the surrounding notation and the instrument or ensemble reading it.
Enharmonic Key Spellings and Practical Choices
Enharmonic keys can use the same sounding pitches on an equal-tempered instrument but spell notes and chords differently. Choose the spelling that matches the notation, instrument, modulation, and harmonic function.
Swipe horizontally inside the table to view every column.
| Sharp-side key | Flat-side key | Signature comparison | Why the spelling matters |
|---|---|---|---|
| F♯ major | G♭ major | 6 sharps versus 6 flats — Six-accidental enharmonic pair | Both are common; surrounding keys often determine the clearer spelling |
| C♯ major | D♭ major | 7 sharps versus 5 flats | D♭ is often easier to read, but C♯ may preserve a sharp-key relationship |
| B major | C♭ major | 5 sharps versus 7 flats | C♭ may appear when flat-side harmonic spelling must remain consistent |
| D♯ minor | E♭ minor | 6 sharps versus 6 flats | Both are relative minors of the enharmonic 6-accidental major keys |
| A♯ minor | B♭ minor | 7 sharps versus 5 flats | B♭ minor is visually simpler, but A♯ minor can preserve C♯ major context |
| G♯ major | A♭ major | 8 sharps including F𝄪 versus 4 flats — Theoretical eight-sharp key | A♭ major is normally preferred as a key signature |
A double sharp (𝄪) raises a written note by two semitones; it preserves letter-name and harmonic spelling.
- • Enharmonic equivalence is exact in twelve-tone equal temperament, but tuning systems and performance practice can treat spellings differently.
- • Do not replace every sharp spelling with a flat spelling; written function matters.
- • The standard circle often compresses enharmonic pairs into one position to remain readable.

The circle is a relationship map, not a complete analysis
The chart cannot identify octave, voicing, inversion, rhythm, meter, phrase structure, modal center, tuning nuance, or borrowed harmony. It also cannot prove a song’s key from the signature alone. Use listening, notation, cadence, bass motion, and harmonic function with the circle.
Common Circle of Fifths Mistakes and Corrections
Most reading errors come from reversing direction, confusing relative and parallel keys, or treating enharmonic spelling as irrelevant.
Swipe horizontally inside the table to view every column.
| Common mistake | Why it is wrong | Correct approach |
|---|---|---|
| Moving clockwise and adding flats | Clockwise motion adds sharps in the standard layout. | Clockwise: C–G–D–A–E–B–F♯ |
| Moving counterclockwise and adding sharps | Counterclockwise motion adds flats. | Counterclockwise: C–F–B♭–E♭–A♭–D♭–G♭ |
| Calling A minor the parallel minor of C major | A minor is the relative minor because it shares C major’s key signature. | C minor is the parallel minor of C major — Relative versus parallel correction |
| Assuming a key signature proves the tonic | Major and relative minor share one signature. | Use cadences, melodic emphasis, and harmonic function to identify tonic |
| Reading axis-like clock positions as pitch height | Clock positions show relationships, not octave register. | Use notation or an instrument to determine register |
| Treating F♯ major and G♭ major as the same written key | Their pitch spellings and harmonic functions differ. | Choose the spelling that fits the musical context |
| Using the circle as a complete chord progression rule | The chart shows relationships, not a required sequence. — Relationship chart limitation | Analyze rhythm, voice leading, chord quality, and form |
| Ignoring minor-scale alterations | Harmonic and melodic minor often raise scale degrees 6 or 7. | Separate the key signature from local accidentals |
Direction assumes the standard chart orientation with C major at 12 o’clock.
- • Some diagrams reverse the visual orientation or label fourths instead of fifths; read the legend before using an unfamiliar chart.
- • The circle is a model of tonal relationships, not a complete analysis of melody, harmony, tuning, or form.
- • Jazz, modal, chromatic, and non-Western systems may use the circle differently or require other tools.

Frequently asked questions
What is the circle of fifths?
The circle of fifths arranges major and minor keys by perfect-fifth relationships. Clockwise movement adds sharps, counterclockwise movement adds flats, and adjacent keys differ by one key-signature accidental.
Why is it called the circle of fifths?
Each clockwise step moves up a perfect fifth, such as C to G or G to D. Continuing through all 12 pitch classes returns to an enharmonic form of the starting pitch.
Which direction adds sharps on the circle of fifths?
Clockwise movement adds one sharp at each step. The common sequence is C, G, D, A, E, B, F♯, and C♯.
Which direction adds flats on the circle of fifths?
Counterclockwise movement adds one flat at each step. The common sequence is C, F, B♭, E♭, A♭, D♭, G♭, and C♭.
What is the order of sharps?
The order of sharps is F♯, C♯, G♯, D♯, A♯, E♯, B♯. Each new sharp key keeps the earlier sharps and adds the next one in that order.
What is the order of flats?
The order of flats is B♭, E♭, A♭, D♭, G♭, C♭, F♭. It is the reverse of the sharp-letter order.
How do I find the relative minor on the circle?
Find the minor key paired with the major key at the same circle position. You can also move down three semitones from the major tonic, such as C major to A minor.
What is the difference between relative and parallel minor?
Relative major and minor share a key signature but use different tonics. Parallel major and minor share a tonic but use different key signatures, such as C major and C minor.
How does the circle show the I, IV, and V chords?
Choose the major key as I. Its counterclockwise neighbor is IV, and its clockwise neighbor is V; for C major, the three chords are F, C, and G.
Do adjacent keys share most of their notes?
Yes. Adjacent major keys share six of seven scale notes and differ by one accidental. That close relationship often supports smooth modulation.
Are F-sharp major and G-flat major the same key?
They are enharmonic in twelve-tone equal temperament, so the sounding pitch classes match. They are not the same written key because their note names and harmonic spellings differ.
Can the circle of fifths identify a song key by itself?
No. A key signature narrows the possibilities, but major and relative minor share the same signature. Cadences, tonic emphasis, melody, bass motion, and chord function identify the actual key.
Can I use the circle of fifths for chord progressions?
Yes, but the circle only suggests root relationships. A complete progression still depends on chord quality, inversion, voice leading, rhythm, style, and tonal goal.
Does the circle include harmonic and melodic minor scales?
The inner minor ring normally labels natural-minor key signatures. Harmonic minor raises scale degree 7, and melodic minor commonly alters scale degrees 6 and 7 without changing the written key signature.
What can the circle of fifths not show?
The circle does not show exact voicings, octave register, rhythm, tuning nuance, modal behavior, non-diatonic harmony, or musical form. Use notation, listening, and harmonic analysis with the chart.
