Circle of 5ths mechanics

* In each direction around the circle either a sharp or flat is added to create the new key.
* The new key created takes the name of the 5th of the previous key in the sharp direction or the 4th of the previous key in the flat direction.
* Going in the sharp direction the 7th degree gets the sharp. Example: G Major gets an F#.
* Going in the flat direction the 4th degree gets the flat. Example: F Major gets a Bb.
* Enharmonic keys have two names for a key that has the same notes. There is really only 12 keys. Three of the keys can go by a different name.
