This application allows you to quickly determine the chords to use when composing your own music. You can also use it to determine the Key (root and mode) of your favorite songs.
Using the rotatable Root and Mode wheels, you can quickly transpose songs into any key you like. Just touch the outer wheel and drag it into the position you want. You can hear an arpeggio and chord any interval by touching the inner wheel. The musical notation is also displayed.
All seven modes are included:
- Ionian (Major)
- Aeolian (minor)
