Circle of Fifths: How to Use It, With Chords in Veena

The circle of fifths arranges the 12 keys in a ring so that each step clockwise moves up a fifth and adds one sharp, and each step anticlockwise adds one flat. Keys next to each other share six of their seven notes, so they sound related and chords from neighbouring keys fit together. Veena, the free AI DAW with a personal music producer built in, puts that to work: set a key and CoProducer writes every part inside it, then moves to a neighbour when you ask for a key change.

The circle of fifths, key by key

Read it like a clock with C at the top.

Step clockwise	Major key	Sharps	Relative minor
0	C	none	A minor
1	G	1	E minor
2	D	2	B minor
3	A	3	F sharp minor
4	E	4	C sharp minor
5	B	5	G sharp minor
6	F sharp or G flat	6 sharps or 6 flats	D sharp or E flat minor
7	D flat	5 flats	B flat minor
8	A flat	4 flats	F minor
9	E flat	3 flats	C minor
10	B flat	2 flats	G minor
11	F	1 flat	D minor

The minor keys are the inner ring: every major key shares its notes with the minor key beside it, which is its relative minor.

What the circle tells you

The chords of a key. A key's main chords are the key itself and its two neighbours. In C major that is C, F and G, the I, IV and V. Add the three relative minors on the inner ring, Am, Dm and Em, and you have the six chords most pop is made of.
Where to modulate. A key one step clockwise or anticlockwise is the smoothest change. C to G lifts a final chorus without sounding like a jolt.
Which keys are close. Distance on the circle is how many notes change. C and F sharp are opposite and share only two notes, which is why a jump between them sounds sharp.
Strong movement. Chords that fall a fifth, like Dm to G to C, pull hardest toward home; the circle shows each of those steps as one notch anticlockwise.

Use the circle in a Veena project

The key lives in Veena's transport bar: 12 roots in major or minor, 24 keys in all. Set it once and CoProducer writes every part in that key. To use the circle, build a part, then ask CoProducer to move around it:

Write a 100 BPM pop chorus in C major with a piano playing C, G, Am, F, a bass on the roots and a soft kick and clap. Eight bars, then a key change up a fifth to G major for the final eight bars, with the same chord pattern in the new key.

CoProducer writes the piano, bass and drums, then the second eight bars in G major, with every part on its own track. Press play and hear a clockwise step: the chords are the same pattern, one notch round the circle. Open the piano in the piano roll to see the one note that changes, F becoming F sharp.

From there, try the relative minor ("the same part in A minor") or a step the other way ("the same part in F major"), and ask for three options for each new part. On a recording, Find Key tells you where your own audio sits on the circle before CoProducer writes around it. Export WAV, MP3 or MIDI, with no watermark.

Frequently asked questions

What is the circle of fifths?

A circle that arranges the 12 keys so each step clockwise moves up a fifth and adds one sharp, and each step anticlockwise adds one flat. Neighbouring keys share six of their seven notes, which is why they sound related. In Veena you can set any of 24 keys from the transport bar and CoProducer writes every part in it.

How do I use the circle of fifths to pick chords?

Take your key and its two neighbours on the circle: in C major that is C, F and G, the I, IV and V chords. Add the relative minors inside the circle, Am, Dm and Em. Veena is an AI DAW with a personal music producer built in. Describe the song you want and CoProducer builds it with you — beats, chords, melody, arrangement and mix — as real tracks you can edit, mix and export. Free, in your browser.

How many sharps or flats does each key have?

C major has none. Going clockwise, G has one sharp, D two, A three, E four, B five and F sharp six. Going anticlockwise, F has one flat, B flat two, E flat three, A flat four, D flat five. In Veena you never count them: set the key and CoProducer writes the notes of that key.

How do I find the relative minor of a major key?

Go to the sixth note of the major scale, or three semitones down from the key. C major's relative minor is A minor, G major's is E minor. They share the same notes and sit at the same spot on the circle. In Veena, set the minor key in the transport bar, or ask CoProducer for the same part in A minor.

How do I do a key change with the circle of fifths?

Move to a neighbouring key, usually one step clockwise, because the two keys share six notes and the change sounds smooth. In Veena, ask CoProducer for a key change into the final chorus, such as up a fifth from C to G, and it rewrites the part in the new key on the timeline, where you can edit every note.
