Circle of fifths: every key, chord and relative minor

Tap a key to see its seven chords, its relative minor and the keys next door. Then use the circle to find the chords of a song, change key or choose a capo.

Without JavaScript, tapping a key jumps to its row in the table below.

How to read it

Start at C, at the top. Going clockwise, each key is a fifth above the one before it and has one more sharp: G has one, D two, A three. Going counter-clockwise, each key has one more flat: F has one, Bb two, Eb three. The two sides meet at the bottom, where F# (six sharps) and Gb (six flats) are the same key under two names.

The outer ring holds the major keys. The inner ring holds the relative minors: the minor key that uses the same notes, starting on the 6. Em sits inside G, Am inside C. The small figure in each key is its signature, the number of sharps (#) or flats (b).

The circle spells each key the way musicians write it: flats for F, Bb, Eb, Ab and Db, sharps for G, D, A, E and B. This table has all twelve, with the three major chords of each.

Find the chords of a song's key

Pick the key of the song. The key and the two keys beside it are the three major chords of the song, the 1, the 4 and the 5. In G they are G, C and D, with C on the left and D on the right.

The three minor chords sit on the inner ring, under them: the 6m under the 1, the 2m under the 4 and the 3m under the 5. In G they are Em, Am and Bm. That makes six of the seven chords, all within a step of each other. The seventh is the diminished 7°, F#° in G. It sits off the circle and turns up rarely.

When a chord outside those seven shows up, the song is borrowing from another key. The chords of all twelve keys are on the chords in every key page, and the Nashville number system writes them as numbers.

Transposing and choosing a capo key

One step on the circle is a fifth. To move a song one step clockwise, move every chord one step the same way. From G to D, G, C, D and Em become D, G, A and Bm. Count the steps and you know the new key without writing anything down.

For a capo, look for a key whose open shapes you know: C, A, G, E and D, and Am, Em and Dm. A song in Bb has awkward barre chords, but with the capo on fret 1 you play it in A shapes. A song in Eb can be D shapes with the capo on fret 1. The capo chart does this for every key, and the chord transposer rewrites a whole chart in the new key.

Changing key in the middle of a song

Keys next to each other on the circle share six of their seven notes and four chords, so a change from one to the next is the smoothest there is. G and D share G, Bm, D and Em. Play one of them and it belongs to both keys, so the ear takes it as the old key and then hears it as the new one. That is a pivot chord.

The usual lift for the last chorus is a different move. Up a whole step, G to A, is 2 steps round the circle, and up a half step, G to Ab, is 5. Far fewer chords are shared, so the change is a jump, which is the point of it.

Four ways round the circle

A cycle is a path through the keys. Use the buttons above the key panel to draw each one over the circle.

  • Fifths, clockwise. C, G, D, A and on, each a fifth above the last. It is the order of keys by sharps. In a song, the move from 1 to 5 is one step this way.
  • Fourths, counter-clockwise. The same circle the other way, each key a fourth above the last. Chords like to fall like this. 2m 5 1 is Am D G in G, and 6m 2m 5 1 is Em Am D G: each chord is one step counter-clockwise from the one before. The Nashville guide has the full run.
  • Major thirds, the triangles. Three keys four places apart: C, E and Ab (also called G#). There are four of these triangles. Harmony that moves by major thirds is known as Coltrane changes, after John Coltrane's Giant Steps.
  • Minor thirds, the squares. Four keys three places apart: C, Eb, F# and A. There are three of these squares. They are the notes of a diminished seventh chord, which splits the octave evenly and works as a passing chord, as in C, C#°7, Dm.

In GraceNote

Transposing takes one tap. Open a song, tap the key to transpose and every chord moves, spelled for the new key: into F you get Bb, not A#. Set a Capo in the editor, or in the Transpose sheet on Stage, and the chart shows the shapes you play.

To see numbers instead of letters, open a song on Stage, tap Display & Style, and on the Chords tab choose Nashville under Notation. The chart then reads the same in every key, which is what the circle teaches. Your song is not changed: switch back to A-G whenever you like.

Questions

Why do the sharps go clockwise?

Each key a fifth higher shares six notes with the one before. The seventh note of the new scale is the one that changes, and it is a half step higher: C has F, G has F#, D adds C#. So every step clockwise adds one sharp, and every step counter-clockwise adds one flat.

What is the relative minor?

The minor key that uses the same notes as a major key. It starts on the sixth note of the major scale: A minor for C major, E minor for G major. On the circle it sits right inside its major key.

Is the circle of fifths the same as the cycle of fourths?

It is the same circle read in the other direction. Clockwise, each key is a fifth above the last. Counter-clockwise, each key is a fourth above the last. People say the cycle of fourths when they follow chords that way, as in 2m 5 1.

How do I know how many sharps or flats a key has?

Count the steps from C. Three steps clockwise is A, with three sharps. Two steps counter-clockwise is Bb, with two flats. The table on this page lists all twelve.

Why does the bottom of the circle have two names?

F# major has six sharps and Gb major has six flats, and they sound the same. The circle prints F#/Gb, and the panel for that key gives the chords of both.
