Circle of Fifths is a clean, fast reference for musicians, songwriters, and students.
Turn the wheel to any key and instantly see its key signature and the seven chords that belong to it. Chords are colour-coded by function (tonic, subdominant, dominant), so the structure of the key is clear at a glance.
- Major and minor keys, with relative keys and correct note spelling (F sharp vs G flat)
- Hear every chord, and the full scale, with a built-in piano sound
- Piano keyboard showing the notes of the selected chord
- Ready-made chord progressions (pop, 50s, ii-V-I, epic minor and more) that you can play in any key
- Key signatures drawn on the staff
- Works on iPhone and iPad, light and dark mode, VoiceOver support
The circle of fifths shows the relationship between the 12 tones of the chromatic scale, their key signatures and the associated major and minor keys. C major sits at the top with no sharps or flats. Each step clockwise adds a sharp; each step counter-clockwise adds a flat.
