Interactive Circle of Fifths

The Circle of Fifths is a fundamental music theory tool that visualises the relationships between the twelve musical keys. This interactive version makes the concept accessible and practical for musicians of all levels. Rather than viewing it as a static diagram in a textbook, you can explore how keys relate to each other, understand chord progressions, and discover which keys work well together. The tool is particularly useful for songwriters, producers, and music students who want to understand why certain progressions feel natural and how to build harmonic structures. By making the Circle of Fifths interactive, the tool transforms abstract theory into something you can experiment with in real time.
