Interactive Circle of Fifths

Welcome to a collaborative hub for musical discovery. The Interactive Circle of Fifths is a dynamic, web-based tool designed to make music theory visual, audible, and deeply intuitive. It transforms the classic circle—a foundational concept for musicians—into a living, interactive workspace where relationships between keys, chords, and scales come to life. This tool is built for a team of learners: from students taking their first steps in theory, to songwriters seeking fresh progressions, and educators looking for a powerful teaching aid. Its core value lies in synergy—it seamlessly integrates hearing with seeing, and theoretical knowledge with practical application on your instrument. By working together with this tool, you can unlock the patterns that form the backbone of Western music, accelerating your understanding and creativity in a unified, cooperative learning environment.
