Interactive Circle of Fifths

The Interactive Circle of Fifths is a dynamic, web-based music theory tool designed to demystify the foundational relationships between keys, chords, and scales. It transforms the classic, static diagram into a living, responsive learning environment where sound meets visualization. This tool is built for a continuous cycle of discovery, allowing musicians at any level—from curious beginners to seasoned composers—to iteratively explore and internalize harmonic concepts. Its core value proposition lies in making abstract theory tactile and audible, enabling users to see chord progressions, hear their emotional impact, and understand their theoretical function simultaneously. By integrating visualizers for both piano and guitar, it bridges the gap between theoretical knowledge and practical instrument application. The tool encourages an ongoing process of improvement, letting you start with simple major chords, cycle through related minors and diminished chords, and progressively layer in complex scales like pentatonic, blues, and harmonized scales. It’s more than a reference; it’s a practice partner for a never-ending journey in musical mastery.
