Interactive Circle of Fifths
Explore neighboring keys, relative minors, key signatures and diatonic chords with an interactive circle of fifths. Click any key on the circle to explore relationships that are useful for harmony and songwriting. Click one of the twelve major keys. The detail panel shows its relative minor, signature, diatonic chords, and neighbors. The tool is designed to give a quick answer without hiding the musical logic. Explore the controls, listen whenever playback is available, and compare alternatives before choosing what fits your song. It is one of the clearest ways to understand key relationships, dominants, relative keys, accidentals, and modulation paths. It also supports harmony study, songwriting, rehearsal, and setlist preparation. Results can be copied and combined with the other tools in the Musician Toolkit. Try the same example in different keys. Comparing scale degrees, intervals, and notes helps you recognize patterns that appear in many songs. Moving by perfect fifths organizes key signatures and places closely related keys next to one another. The panel shows the relative minor for every selected major key. Yes. Neighboring keys share many notes and chords, which makes them natural modulation destinations.Interactive Circle of Fifths
