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!

JUST SPIN THE WHEEL TO CHANGE YOUR KEY!


Theo makes it quick and easy to find chords that sound amazing together. Just spin the wheel to your desired key and you're set! Our window shows you all the notes and chords in that key and hides the rest.

USEFUL FOR ALL SKILL LEVELS


Theo is great for beginners that just want to know what chords to strum on their acoustic guitar, perfect for church bands where members are struggling to keep up or follow along, and so handy for studio pros to transpose songs on the fly.

FUN & EASY


Music Theory used to be a scary thought. Our mission is to make it fun and easier, because the end goal is to leave this world with more music makers.
