The Circle of Fifths is essentially a tool used by musicians to help them understand the various keys of music, to help transpose music into a different key, to compose new songs and to understand scales and modes of music. Its extremely helpful and is something every guitarist should be very familiar with.
It is however somewhat involved and can be very confusing at first. It is for this reason I created this post. Below you will find a number of links that will lead you to various articles, tools and videos that will further explain the Circle of Fifths and how you can use it to help you become a better musician. There are tests, quizzes and interactive programs within the links below that will keep you busy for hours as well as help burn these concepts into your memory. I hope you enjoy and find this post helpful. If so, please feel free to leave a comment in the comments box below. Thanks!
