To find our three o’clock key, jump a fifth above D, and you’ll land on A, which means it will be A major. If we jump a perfect fifth above G, that lands us on D, which means our two o’clock key signature must be D major. Now, let’s find the next key signature at two o’clock. This explains why this diagram is called the circle of fifths. Why is this important? Each tick or key signature on the circle of fifths is a perfect fifth away from the previous one, so that means our key signature at one o’clock must be G major. This distance of seven half steps is called a perfect fifth. Start on C and go up seven half steps or semitones, and you should land on G. To visualize this, look at your piano or keyboard. How can we find what key signature this one is? Let’s jump to the next tick at one o’clock. This is our foundational key signature since it doesn’t contain any sharps or flats. Each tick stands for one of the 12 major key signatures. Start by drawing a circle and placing twelve tick marks around it, just like a clock.
