Meet, Theo! Music theory in the palm of your hands. We've taken the complicated circle of fifths and the Nashville number system and combined them into one, easy to use tool.
No more clutter from stacks of theory books or getting lost in the endless sea of online content. Simply rotate the wheel to your desired key and our window shows you only the notes and chords in that key, and hides the rest.
So grab Theo, your favorite instrument and spend more time writing!
