Complete 12-Key Reference Table: Sharps, Flats, Relative Minors & Chord Neighbors
First codified in 1677 by Nikolai Diletsky and refined by Johann David Heinichen in 1728, a printable circle of fifths organizes all twelve chromatic pitch classes by harmonic proximity rather than keyboard adjacency. Moving one step clockwise raises the tonic by a perfect fifth (7 semitones) and adds one sharp following the invariable order F♯ – C♯ – G♯ – D♯ – A♯ – E♯ – B♯. Moving one step counter-clockwise raises the tonic by a perfect fourth (5 semitones) and adds one flat in exact reverse order: B♭ – E♭ – A♭ – D♭ – G♭ – C♭ – F♭.
| Clock Position | Major Tonic | Relative Minor | Signature | Primary I – IV – V – vi Chords |

| 12 o'clock | C Major | Am minor | 0♯ / 0♭ | C – F – G – Am |
| 1 o'clock | G Major | Em minor | 1♯ (F#) | G – C – D – Em |
| 2 o'clock | D Major | Bm minor | 2♯ (F# C#) | D – G – A – Bm |
| 3 o'clock | A Major | F#m minor | 3♯ (F# C# G#) | A – D – E – F#m |
| 4 o'clock | E Major | C#m minor | 4♯ (F# C# G# D#) | E – A – B – C#m |
| 5 o'clock | B / Cb Major | G#m minor | 5♯ (F# C# G# D# A#) | B – E – F# – G#m |
| 6 o'clock | Gb / F# Major | Ebm minor | 6♭ (Bb Eb Ab Db Gb Cb) | Gb – Cb – Db – Ebm |
| 7 o'clock | Db / C# Major | Bbm minor | 5♭ (Bb Eb Ab Db Gb) | Db – Gb – Ab – Bbm |
| 8 o'clock | Ab Major | Fm minor | 4♭ (Bb Eb Ab Db) | Ab – Db – Eb – Fm |
| 9 o'clock | Eb Major | Cm minor | 3♭ (Bb Eb Ab) | Eb – Ab – Bb – Cm |
| 10 o'clock | Bb Major | Gm minor | 2♭ (Bb Eb) | Bb – Eb – F – Gm |
| 11 o'clock | F Major | Dm minor | 1♭ (Bb) | F – Bb – C – Dm |
For songwriters and worship band leaders, the circle of fifths chart doubles as an instant modulation map: borrowing the secondary dominant (V/V) simply means looking two steps clockwise from your home key, while smooth pivot-chord modulations share four to six scale tones with either adjacent neighbor.

Frequently Asked Questions
- How do you read the outer, middle, and inner rings of a Circle of Fifths chart?
- The outer ring displays the 12 Major tonics moving clockwise by ascending perfect fifths (C, G, D, A, E, B, F♯/G♭) and counter-clockwise by ascending perfect fourths (F, B♭, E♭, A♭, D♭). The middle ring aligns each Major key with its relative natural minor (such as C Major with A minor), and the inner ring plus radial staves show the exact number of sharps or flats in the key signature.
- How can I find the I, IV, and V chords of any key on this printable Circle of Fifths?
- Pick any Major key on the outer ring as your tonic I chord. The wedge immediately counter-clockwise (one step left) is its subdominant IV chord, and the wedge immediately clockwise (one step right) is its dominant V chord. The three relative minor wedges directly beneath those three Major wedges give you ii, iii, and vi—all six primary diatonic triads grouped in one contiguous six-chord neighborhood.
- Does the 2×2 classroom wall poster PDF work on standard US Letter or A4 printers?
- Yes. Clicking '2×2 Classroom Wall Poster (4 Sheets)' slices the vector Circle of Fifths chart across four standard US Letter or A4 pages with precision alignment crop marks and glue margins so music teachers can assemble a crisp 17 × 22 inch band-room reference poster without needing a wide-format plotter.
- Why are F♯ Major / G♭ Major and C♯ Minor / D♭ Minor shown together at the bottom of the wheel?
- At the 5-, 6-, and 7-accidental positions (B/C♭, F♯/G♭, and D♭/C♯), keys share identical sounding pitches in twelve-tone equal temperament—called enharmonic equivalents—allowing composers and arrangers to choose whichever spelling uses fewer double-sharps or double-flats.
