Probably the single biggest way to use the circle of fifths is in modulation (or changing key) in your songwriting and composition. The perfect cadence A perfect cadence, also called a 5-1 ('Five One') is the name for a two chord sequence of chord 5 in a key, followed by chord 1 in that —e.g. A G major chord (chord 5) to a C major chord. The circle of fifths diagram reveals several important musical relationships and is one of the most important tools available to a musician. The circle of fifths diagram shows the relationship between major and natural minor keys as well as the most frequently used intervals for. Introduction The Circle of Fifths is a geometric representation of how the 12 notes of the chromatic scale relate to one another. If you look closely at the diagram you will see each note is a Perfect Fifth (seven semitones, or seven frets on the fretboard) higher than the next (going clockwise). The circle of 5ths, sometimes referred to as the circle of 4ths and 5ths, is a chart that reveals many patterns of melody and harmony in music. Many students will brush it aside as another boring theory assignment but the Circle of 5ths is actually the key to easy memorization of so many music concepts.

What is the Circle of 5ths?
The circle of fifths is a diagram used in music theory that helps students memorize and understand the 24 major and minor keys used in music, key relationships, and many chord relationships.
Logically, this diagram is pretty fascinating. It ties together many common relationships found in music. The circle of fifths illustration was conceived by German musician Johann David Heinichen in 1728.
Memorizing the circle of 5ths diagram is worthwhile. It’s not as hard as it seems once you understand the logic behind the circle.
In this lesson we will just examine the idea of fifths and fourths on the circle. In following lessons, we'll apply it to keys, chord progressions, and the like. (If you’re still unsure of the basic musical intervals, you should review them before proceeding.)
How Does the Circle of Fifths Work?
Fifths are musical intervals. The circle of 5ths is an arrangement of the 12 notes of the musical alphabet in a circle. Each note on the circle is a perfect fifth apart.
At the top of the circle we begin on the note C. As you go clockwise around the circle, the notes move in perfect 5ths.
A perfect fifth above C is G, and G is the next note on the circle going clockwise.
A perfect fifth above G is D. D is next on the circle.
Next, a perfect fifth above D is A, and so on. Clockwise, the circle moves through all 12 notes of the musical alphabet going in 5ths finally returning to C.
You will notice at the bottom of the circle three of the notes (B, F♯, and C♯) have two spellings each. The same pitch can have multiple spellings. These are called enharmonic notes. On the circle B and C♭ are enharmonic equivalents. F♯ and G♭ are equal. And, C♯ and D♭ are the same note. If you are confused about this, read over the musical alphabet lesson.
The Circle of Fourths
You may notice I call it a circle of 5ths and 4ths. Fourths are another musical interval. If you go counter-clockwise on the circle you will see the notes go in ascending perfect fourths.
From C, a perfect fourth above is F. A perfect fourth above F is B♭, and so on. The notes go in 4ths all the way around the circle when moving counter-clockwise.
Memorizing the Circle of 5ths and 4ths
It will be quite useful for you to memorize the sequence of note names in both fifths and fourths. For starters, bassists play lots of fifths. Knowing the fifth above any note will come in handy. Also, you will see many chord progressions move in fourths. And, it will make memorizing keys and key signatures easier, too.
Learn to recite the notes on the circle from memory. Be able to start on any note (not just C) and go all the way around the circle in both directions. You already know four of them – your bass is tuned in fourths: E A D G. Backwards is G D A E – fifths! This is something you can practice in your head without your bass.
All you really need to remember is BEAD GCF. The cycle of fourths is BEADGCF with natural notes, followed by BEADGCF with flats. Notice F♭ would be equivalent to E. Somewhere you have to flip to the enharmonic equivalent in order to go all the way around.
5ths are the same only backwards — FCGDAEB.
4ths: | C | F | B♭ | E♭ | A♭ | D♭/C♯ | G♭/F♯ | C♭/B | E | A | D | G | (C) |
5ths: | C | G | D | A | E | B/Cb | F♯/G♭ | C♯/D♭ | A♭ | E♭ | B♭ | F | (C) |
Applying the Circle of Fifths and Fourths
Just laying out the notes in 5ths and 4ths isn’t anything amazing. But, when you look at the keys for each note an interesting pattern occurs and helps you memorize the notes in each key. In the next lesson I will explain major keys on the circle of fifths.

What Is The Circle Of Fifths? A Definition
The circle of fifths describes the relationship between the twelve notes of the chromatic scale and their corresponding key signatures.
Each of the 12 notes in the circle of fifths is a perfect fifth higher than the preceding note. The sequence loops around all twelve notes of the chromatic scale before returning to the starting note.
As well as showing the relationship between every note of the chromatic scale and every potential key signature, the circle of fifths can be used as a visual aid for remembering the number of sharps or flats in each key signature.
The circle of fifths can also be used as a composition tool; pieces often move to neighboring key signatures in the circle when they change key.
The Circle Of Fifths Explained
The above definition is quite a mouthful, so for the rest of the page we’ll go over what it actually means.
The chromatic scale consists of 12 notes. If you ignore the octave at which the notes are played then the 12 notes of a chromatic scale represent every possible note.
The circle of fifths applies to western music theory; some non-western musical traditions have intervals smaller than a half-tone between notes.
The circle of fifths shows us that a sequence of notes in which each note is a perfect fifth* higher than the previous note will eventually return to the original note – after having been through every note of the chromatic scale.
* A perfect fifth interval is the equivalent of seven half-tones (i.e. seven frets on a guitar).
The sequence is circular, so the above applies with any starting note.
Notes In The Chromatic Scale
Starting on a C, and rising up a half-step between each note, the twelve notes of a chromatic scale are:
- C
- C# / Db*
- D
- D# / Eb*
- E
- F
- F# / Gb*
- G
- G# / Ab*
- A
- A# / Bb*
- B
The pairs of notes marked with an asterisk are what’s known as enharmonic equivalents; they’re the same note with two different names.
The diagram below shows the circle of fifths starting on C. As you can see, all of the notes in the chromatic scale above are included in the circle of fifths.
Basic Circle Of Fifths Diagram
When represented visually, the circle of fifths consists of a circle whose circumference has been divided into 12 parts, just like a clock face.
At each ‘hour’ on the circle of fifths diagram is one of the 12 notes of the chromatic scale.
The note at the twelve-o-clock position is a C. The note at each subsequent position (moving clockwise) is a perfect fifth higher than the previous note.
Therefore the complete sequence of notes is as follows: C, G, D, A, E, B, F# / Gb, C# / Db, G# / Ab, D# / Eb, A# / Bb, F
Moving counter-clockwise, each note is a perfect fourth higher than the previous note. See the ‘Circle of Fifths Vs The Circle of Fourths‘ section, below.
In the circle of fifths, any enharmonic equivalent (i.e. the same note with a different name) of a note is regarded as the same note. Therefore an F# (F sharp) is regarded as being the same as a Gb (G flat).
As you can see from the diagram, a sequence of notes that moves in intervals of a perfect fifth will eventually return to the original note – whatever the starting note. The sequence will contain all twelve notes of the chromatic scale.
In other words, wherever you start on the circle of fifths, after twelve steps (which will contain every possible note) you’ll be back where you started.
The Circle Of Fifths And Key Signatures
Inside the smaller circles in the circle of 5ths diagram are the number of sharps or flats in the corresponding key signature (i.e. C major has 0 sharps or flats, D major has 2 sharps, E flat major has 3 flats, etc.).
The circle of fifths diagram at the top of the page (and repeated below) shows the notes of the chromatic scale and their corresponding key signatures.
We can therefore use the circle of fifths to memorize the number of sharps or flats in every key signature. (See below for an explanation of what a key signature is.)
What Is A Key Signature – A Reminder
Circle Of Fifths Diagram Pdf
A key signature is a group of sharps or flats that appears after the clef in a musical staff. It tells the performer which notes should be sharpened or flattened in the music that follows.
The number of sharps of flats in the key signature indicates the key that the music is in.
In the piece of music above (Twinkle, Twinkle Little Star), there are three sharps in the key signature. Therefore the piece is either in A major or its relative minor, f# minor*. (Note the convention of referring to minor keys using lower case letters.)
Each key signature can be one of either two keys: a major key or its relative minor. The relative minor is always a minor third lower than the major with the same key signature.
* The above piece is clearly in A, not least because the phrase starts and ends on A notes. There are many clues by which you can tell just by looking whether a piece is in a major or minor key, but it is outside the scope of this article to cover this in detail.
The absence of any sharps or flats means that a piece is either in C major or its relative minor, a minor.
The circle of fifths contains all twelve major and all twelve minor keys.
Progressing clockwise around the circle of fifths results in the following keys, as shown below:
- C major / a minor: 0 sharps or flats
- G major / e minor: 1 sharp
- D major / b minor: 2 sharps
- A major / f# minor: 3 sharps
- E major / c# minor: 4 sharps
- B major / g# minor: 5 sharps AND Cb major / ab minor: 7 flats
- F# major / d# minor: 6 sharps AND Gb major / eb minor: 6 flats
- C# major / a# minor: 7 sharps AND Db major / bb minor: 5 flats
- Ab major / f minor: 4 flats
- Eb major / c minor: 3 flats
- Bb major / g minor: 2 flats
- F major / d minor: 1 flat
- C major / a minor: 0 sharps or flats
Moving clockwise around the circle of fifths from the C adds a sharp to each key signature until C# major / a# minor – which have 7 sharps – is reached.
Moving anti-clockwise from the C adds a flat to each key signature until Cb major / ab minor – which have 7 flats – is reached.

Note that some keys have enharmonic equivalents.
The Circle Of Fifths Vs The Circle Of Fourths
Moving counter-clockwise round the circle of fifths results in the circle of fourths. In the circle of fourths, each step represents an interval of a perfect fourth.
Many chord progressions move in 4ths. For this reason some musicians (particularly jazz musicians) prefer to learn the circle of fourths rather than the circle of fifths. Both amount to the same thing, but just seen from a different perspective.
What Is The Circle Of Fifths – Conclusion
- The circle of fifths shows us how notes and key signatures are related.
- Moving in perfect fifths from any start note will result in a sequence of notes that includes every chromatic note before returning to the start note.
- Moving in a clockwise direction from the top of the circle of fifths adds a sharp to each key signature until C# major / a# minor is reached.
- Moving anti-clockwise from the top of the circle of fifths adds a flat to each key signature until Cb major / ab minor is reached.
- Moving anti-clockwise around the circle of fifths results in the circle of fourths.
