Introduction
“What exactly do I do with the circle of fifths?” The circle of fifths chart organizes musical keys and modes. Also, it helps you understand the relationships in music, making various tasks easier. Keep reading to learn more.
This post uses musical terms. For definitions, see the Glossary at the end of the article.
The Circle of Fifths: Let’s Take a Look at the Chart
Mobile users: for best results reading the examples, tilt your screen 90o to the right.
“What exactly do I do with the circle of fifths?” You use it to organize the twelve major and twelve minor keys:
- When you move clockwise around the chart, you lose flats or gain sharps and vice versa.
- In addition, closely related keys sit next to each other on the chart.
- For example, C and G major have all the same notes except one (F#). Likewise, C and F major have all the same notes except one (Bb).
Thus, the chart is useful when you need to change keys (for more information, see section #4). Also, it’s useful for when you need to transpose a melody to fit the singing range of your voice.
Why are there two scale labels on each staff on the chart?
- The major mode is above each staff and the minor mode is below.
- When major and minor modes have the same notes, we call them relative modes.
- However, each mode emphasizes different notes, making major and minor modes sound very different.
Therefore, the chart is useful when you need to change modes (for more information, see section #4).
What are enharmonic keys?
- The C# and Db major scales, F# and Gb major scales, and B and Cb major scales are called enharmonic keys, because the scale pairs contain the same notes.
- For example, the F# and Gb major scales have all the same notes on the keyboard, but one is “spelled” with sharps and the other with flats.
- Try it! Take the notes from the F# and Gb major scales (see the scales in the next section) and play them on the keyboard.
In addition, enharmonic keys can have white key sharps and flats:
- E# = F
- B# = C
- Fb = E
- Cb = B

The Circle of Fifths: Now Let’s Look at How the Major Scales Can Be Organized Using the Chart
Why’s it called “the circle of fifths?”
- Because the tonic notes of adjacent keys are five notes apart on the keyboard
- The scales in this section are organized in the same order as the clockwise sequence on the circle of fifths chart.
- For example, the tonic of G major is five notes away from the tonic of the key of D major.
Every time you move to a key with a tonic five notes away, you lose or gain either sharps or flats depending on the direction you move on the chart.
Why does this pattern happen?
- The pattern of whole and half steps in the major scale’s construction makes this cyclical pattern of keys work.
- The chart was created to take advantage of this effect.
- For more information on scale construction, see section #4.
B and Cb major are enharmonic keys:
F# and Gb major are enharmonic keys:
C# and Db major are enharmonic keys:

Final Thoughts on “What Exactly Do I Do with the Circle of Fifths?”
Here’s a summary:
- The circle of fifths chart organizes the twelve major and twelve minor keys, helping you to change keys or modes as well as to transpose music.
- When major and minor keys all have the same notes, we call them relative keys.
- The C# and Db, F# and Gb, and B and Cb major scales are the three enharmonic keys.
