Music Theory, Part 2, The Circle of Fifths and Scales

The circle of fifths. What is it, why would I use it.

As you travel on your musical journey you'll certainly read or hear about the circle of fifths. It's a learning tool that helps you remember several important concepts. There are many examples on the internet, just Google circle of fifths. The circle teaches you key signatures, how many sharps or flats are in each key, which chords go together, and the relative minor chords. Going clockwise around the circle you learn the sharp  # keys,  going counterclockwise you learn the flat b keys. This helps you learn how to play in different scales. The letters around the top can also help you remember what the 3 main chords are in each scale. Pick a letter, then go clockwise 1 and counterclockwise 1 to get the 3 chords that are most common.

Relative Minors.

No, they're not your young children. Every scale has 2 letters that use the name number of sharps or flats. So C Major and A Minor have the same number, in this case zero, of sharps or flats. To play either one you just start on the first letter and then go through the 7 letters we use in music until it comes back around. For example: C-D-E-F-G-A-B-C is the C Major Scale while A-B-C-D-E-F-G-A is the relative minor.

How is this useful?

By knowing which chords go with which scales you can learn songs more quickly. The other advantage is that it will help you follow along when practicing or jamming with other musicians. This is just a brief explanation, so if you'd like to explore the circle further, do some research or have your guitar teacher go over it with you. It can definitely make figuring songs out a lot easier.
