The Circle of Fourths is a great exercise in getting to know all the keys and they relate to one another. Here’s an overview of how the circle works. I have a theory sheet on my site that can be a great aid to looking through this. Although it’s not in a circle, it’s a grid of all the keys one after another. Hope you like it!
