Theo Wheel puts music theory at the fingertips of teachers, students & aspiring musicians with one organic, handcrafted tool.
The Theo Wheel is a physical representation of the circle of fifths which is used in music theory to learn scales, corresponding key signatures, and associated major and minor keys. The design of the Theo Wheel is also helpful in composing and harmonizing melodies, building chords, chord progressions and modulating to different keys within a composition. Unlike standard memorization, you actually have a tangible piece in your hands which is much easier for some people, including me, to internalize that way.
Designed and made in Indiana by Andrew Wellman.
