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.
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.
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.
"I picked one of these up from my local music studio and it's been very helpful for quick reference while writing."

"I think this thing would have helped me actually stick with my music lessons way back when. The theory/math was pretty hard for me.."
