Circle of Fifths
Designed by Thornepalmer
About 2600 years ago Pythagoras created the Pythagorean circle based on the series of harmonics he discovered in vibrating strings. This later would become our circle of fifths. It's still the simplest way for us to visualize the keys and their relationships to one another.
