Zigzag of Fifths app for iPhone and iPad

Key signatures are easy to understand and use with this fun alternative to the circle of fifths!

Simply drag the window along the Zigzag of Fifths to change which 7 notes are shown within the window. Each set of 7 notes is a Note Team with a unique key signature that shows which notes on the team are sharp or flat.

Switch between major and minor modes to change the tonic note, or Team Captain. Listen to the scale to hear how changing the musical mode changes the sound of the Note Team.

Switch to piano view to visualize how sharps and flats are added on the piano keyboard.

Pick your preferred way to visualize the notes - as note letter names or Note Team characters.
