Interactive Circle of Fifths

Click any key on the chart to see its scale, its relative minor and the seven chords that belong to it, and hear every one of them played.

relative minorThe relative minor is the minor key that shares the same key signature as a given major key. It uses the same notes but starts from a different root note. For example, C# minor is the relative minor of E major.
scaleIn the Circle of Fifths, scales are connected by a series of fifths, illustrating the relationship between key signatures. Moving clockwise, each scale adds a sharp or subtracts a flat, revealing the progression through major and minor keys.
chordsThe Circle of Fifths demonstrates how chords are interrelated. Chords adjacent on the circle share common tones and smoothly transition into one another, making them ideal for building progressions and modulating between keys.

Understanding the Circle of Fifths

The Circle of Fifths is a powerful tool that visually represents the relationship between the 12 major and minor keys in music. Starting at C major, each step clockwise moves up by a perfect fifth, adding one sharp to the key signature. Conversely, moving anticlockwise adds flats. This simple structure helps musicians understand key signatures at a glance, making it easier to play in different keys and quickly identify sharps or flats.

Chord progressions on the circle of fifths

Chords that sit next to each other on the circle share most of their notes, which is why they move into one another so easily. One step clockwise from your key is the dominant (V), one step anticlockwise is the subdominant (IV), and the key directly inside yours on the minor ring is its relative minor (vi). In C major that gives you G, F and Am, and those four chords are most of popular music.Here are four progressions written out in C, with where each one sits on the circle. Open any chord to see its notes and hear it on its own.

ProgressionIn C majorOn the circle
I – V – vi – IVC – G – Am – FC sits between F and G on the outer ring, and Am is directly beneath C on the inner ring. The whole progression is three neighbouring slices.
ii – V – IDm – G – CEach chord is one step anticlockwise from the last. Walking the circle backwards is what makes this sound like it is resolving.
vi – IV – I – VAm – F – C – GThe same four slices as I – V – vi – IV, started on the relative minor instead of the major.
I – vi – ii – VC – Am – Dm – GAfter the relative minor it moves two steps anticlockwise and walks back, which is why the turnaround feels circular.
The one chord the circle does not draw is the diminished one. Every major key has a diminished chord on its seventh degree, so C major has B diminished and G major has F sharp diminished. Click a key on the chart above and it turns up in that key’s chord list, ready to play, even though it has no slice of its own on the ring.If you want more progressions than the four above, there is a walkthrough of the ones that have lasted in six time-tested chord progressions, a plain-language explainer in what is a chord progression, and every chord on the circle has a reference page in the chord finder. To go the other way and start from a description rather than a key, the chord progression generator writes one for you and plays it back.

Major and Minor Key Relationships

Another key aspect of the Circle of Fifths is its relationship to minor keys. Each major key has a corresponding relative minor that shares the same key signature (e.g., A minor for C major). This makes it easier to switch between major and minor keys or transpose music. In short, the Circle of Fifths is a go-to tool for both beginners and experienced musicians to master key signatures, chord progressions, and harmony.

Conclusion

In essence, the Circle of Fifths simplifies the complexity of music theory, offering a clear map of key signatures, chords, and relationships between notes. Whether you're composing, learning new music, or improvising, this tool serves as a reliable guide to understanding and creating music more fluidly. It’s a must-have for any musician looking to deepen their theoretical knowledge and enhance their playing skills.

Circle of fifths questions

How do you use the circle of fifths?

Find your key on the ring, then look at its immediate neighbours. The key one step clockwise is your dominant (V), one step anticlockwise is your subdominant (IV), and the key directly inside it on the minor ring is its relative minor (vi). Those four chords cover most popular music. On the chart above, clicking a key shows its scale and every chord in it, and plays them.

What is the circle of fifths?

It is a diagram of the twelve keys arranged so that each step clockwise moves up a perfect fifth and adds one sharp to the key signature. Going anticlockwise moves down a fifth and adds a flat. Keys that sit next to each other share almost all of their notes, so the layout doubles as a map of which chords sound good together.

Where are the diminished chords on the circle of fifths?

The circle shows the major and minor keys, not the diminished chord that also belongs to every key. In a major key the diminished chord is built on the seventh degree, so in C major it is B diminished, and in G major it is F sharp diminished. Click a key on the chart above and it appears in that key’s chord list.

Is this circle of fifths chart free?

Yes. The chart, the scale and chord readouts for every key, the playback and every chord reference page are free to use, with no sign-up.
