- Start at the top of the circle with C Major (0 sharps/flats).
- Moving clockwise, each step adds one sharp: G Major (1 sharp), D Major (2 sharps), A Major (3 sharps), E Major (4 sharps), B Major (5 sharps), F♯ Major (6 sharps), C♯ Major (7 sharps).
- Moving counterclockwise from C Major, each step adds one flat: F Major (1 flat), B♭ Major (2 flats), E♭ Major (3 flats), A♭ Major (4 flats), D♭ Major (5 flats), G♭ Major (6 flats), C♭ Major (7 flats).
- The inner “Minor” circle contains the relative minor keys for each major key, found by going down a minor third (or up a major sixth) from the major key: A minor (relative of C Major), E minor (G Major), B minor (D Major), F♯ minor (A Major), C♯ minor (E Major), G♯ minor (B Major), D♯ minor (F♯ Major), A♯ minor (C♯ Major), F minor (D♭ Major), C minor (G♭ Major), G minor (D♭ Major), D minor (A♭ Major), A minor (E♭ Major), E minor (B♭ Major), B minor (F Major).
- Fill in the outer “Major” ring clockwise: C, G, D, A, E, B, F♯, C♯, then continue counterclockwise: F, B♭, E♭, A♭, D♭, G♭, C♭.
- Fill in the inner “Minor” ring clockwise starting opposite C Major: A, E, B, F♯, C♯, G♯, D♯, A♯, then continue counterclockwise: F, C, G, D, A, E, B.
