The idea for the Guitar Wheel™ began over 13 years ago as Dennis Cheatham tried to grasp the mystery of music theory. During this learning process, he envisioned a “tool” that would serve as a reference library of music theory and act as a teaching aid, chord finder, transposing dial, and composing tool all in one. It would have one side for guitar and the other side for piano. After many years of balancing family life, his job, and product development, he completed work on his teaching aid; the Guitar Wheel™ was born!
