Click any major key on the outer ring or its relative minor on the inner ring to see its relatives and closely related neighboring keys.
Click any key on the wheel to see its details.
The 12 major keys are arranged clockwise around the outer ring starting at C, with each step clockwise moving up a perfect fifth and adding one sharp to the key signature (or removing one flat). Each major key's relative minor sits directly inside it on the inner ring, at the same position on the wheel, since a major key and its relative minor share the exact same key signature. The two keys immediately next to any selected key on the wheel are its closely related keys — they differ by only one accidental.
The outer ring shows all 12 major keys; the inner ring shows their relative minors in the same rotational order.
Clicking any key highlights its major/minor pair and lists both in the info panel below.
The wheel's neighbors on either side of a selected key share all but one sharp or flat, which is why they're commonly used for smooth key changes.
It's a diagram that arranges all 12 major keys (and their relative minors) in a circle so that each step clockwise moves up by a perfect fifth and adds one sharp to the key signature, while each step counter-clockwise moves down a fifth and adds one flat.
The two keys directly next to a chosen key on the wheel are its closely related keys. They sit a perfect fifth away and share all but one accidental (sharp or flat) with the selected key, which is why they tend to sound harmonically close to it.
Each major key on the outer ring has its relative minor directly inside it on the inner ring, at the same position on the wheel. Clicking either one selects that same major/minor pair.
No. This is a purely visual reference and music theory tool; it does not generate, play, or record any sound.
Those are enharmonic keys — the same pitches written and named two different ways depending on the musical context. Both names are shown since either is commonly used.
