The Circle of Fifths

One of the most important visual organizers in music is the circle of fifths. This chart has a number of variations, but it's main job is to help you to see the systematic way in which our key signatures are constructed and ordered.

You might ask, "Why do we call this the circle of fifths?" The name derives from the fact that if you move clock-wise around the circle (starting with the key of C major for instance) you will see the interval (distance) from one key to the next is the interval of a fifth (C major - G major - D major, etc.).

As we explore the construction of major scales, this chart is a handy visual reminder of the mathematical certainty and order in music. Keep it handy.
