The Guitar WheelTM is a all-in-one quick reference guide and study tool for music theory and for all musicians and for all instruments.

The Guitar Wheel is a visual two-sided music theory tool  covering every musical key. The curved guitar neck design on the Guitar Side allows for easy visualization of theory on the guitar. Flip it over to the Piano Side for more in-depth music theory for piano, or any instrument, and even vocalists. It is an excellent study tool and a songwriting/composing tool for schools, colleges, and universities. Instructions include Spanish and German translations.

We created the Guitar Wheel because musicians want and need a all-in-one quick reference for music theory. The Guitar Wheel  is also more convenient than other options. There aren’t hundreds of pages to thumb through looking for answers. It’s always on, you don’t need a power adapter or batteries. And if  accidentally spill your coffee on it, just wipe it off and it’s good as new.

I ordered two of these a few months ago, and now I wanted to order some more. For some reason, they keep walking out of my house and into my friends houses (you should really make a version that doesn't have legs). But seriously, my friends are loving these and taking mine, so I need to order some more.

This is just what I have been looking for to teach my students music theory. This is great.

The Guitar Wheel has two sides which display music theory in a unique way. The Guitar Side helps guitarists visualize how music theory works, the way many guitarists are used to thinking about music—on their guitar fretboard! The Piano Side is a sizable music theory reference for any musician. Included on the Piano side are a piano staff and piano keyboard as supportive reference.

Studying music theory in any key is made possible by turning the key selector tab. Find quick answers to questions on the go or study it to better understand music theory. The more you look at the Guitar Wheel, the more “jumps out” at you and the mysteries of music theory will begin to unravel.

When you’re ready, feel free to browse all the Guitar Wheel videos, read instructions on how to use the Guitar Wheel, buy the Guitar Wheel, or locate a music store where you can purchase a Guitar Wheel.
