Good "Fifths"

The Famous Circle of Fifths
These Fifths Are Not Intoxicating I've heard about the "Circle of Fifths" since I was a teenager, but it never made sense until recently. Another mental block knocked over. This is a very simple tool for musicians of all stripes.
How Does the Circle of Fifths Work? Look at the circle below, and we'll walk through the basics. Think of a clock, with C occupying the 12:00 position.
First, everything starts from C, since C is the key in which there are NO sharps or flats. As we move clockwise from C, each note is a fifth above the last. So G is the fifth of the C scale, D is the fifth of the G scale, and so on. Starting with G, each new key going clockwise has one more sharp note in its major scale. You can test if you wish, by building a major scale on each note. If we move counterclockwise from C, each note is a fifth below the prior note. And, just as with sharps, each scale to the left of C adds a flat note. Note that at the 6:00 position, there are two notes -- F# and Gb. These, of course, are enharmonic notes -- they sound exactly the same and are the same. Their names are different only because they are reached from different directions.

this is not my original contribution, but rather borrowed from http://www.folkblues.com/theory/circle_5ths_text.htm, where you can find out more about Music Theory for the Simple Minded :)

Happy Rain Day, folks!
