Last issue we showed how the Circle of 4ths revealed both the "fam" (primary chords I, IV, and V) and the "cousins" (II, VI, and III).

But it shows much more than that -- in fact, the Circle of 4th reveals at least 10 secrets of chord relationships:

1. The primary chords for each key (the fam).

2. The secondary chords for each key (the cousins).

3. The way chords "want" to move -- up a 4th.

4. The least-likely chords in any key.

5. The order of the flats.

6. The order of the sharps.

7. How many sharps or flats each key contains.

8. Which chords are enharmonic.

9. Which keys are enharmonic.

10. The relative minor key of each major key.

Here is the Circle of 4ths again (remember to mentally bend it into a circle, with C at the top):

C  F Bb (A#) Eb (D#) Ab (G#) Db (C#) Gb (F#) B (Cb) E (Fb) A D G

Looking at the circle, what are the primary chords in the Key of E?

What are the secondary chords in the Key of E?

What chord would normally follow E? (Hint: up a 4th).

Which chords are the most un-likely in the Key of E?

What is the order of the flats? (In other words, if there are 7 flats in a key, what are they, and what is their order?)

What is the order of the sharps? (In other words, if there are 7 sharps in a key, what are they, and in what order will they occur?)

How many flats or sharps are there in the Key of E?

What chord is enharmonic with C#?

What key is enharmonic with Bb?

What is the relative minor key to F?

Rather than discussing the answers to these questions now, I'm going to let you think about this for a week, and next issue we will cover both the answers and the logic behind the answers.
