Circle of Fifths

It's a fancy-looking dartboard. Just kidding. As a musician, you will definitely appreciate this beautiful Circle of Fifths, especially if you ever struggle with the sharps and flats. From now on, changing keys will be much more fluent in front of a mirror. However, you probably won’t be allowed to wear this to your music school exam.
