- Circle of Fifths Wheel & Music Theory Book – Music Learning Tool - For All Instruments & All Levels – Learn Chords, Keys & Progressions – Write More, Play More, Master Music

I will update my review. but now, first impression is...Product well done, well packaged, easy and convenient to use and understand with accompanying booklet for further explanation and instructions how to use more than just a circle of fifths.

Great quality. Easy to operate and very useful.

Very useful well thought out device.

Very good assistance for a beginning bassist attempting to learn music theory.

I now play the Harmonica with a small Western music group. I was having a tough time with all the key changes, minor keys, and transposing. Man, how I wished I'd have learned this "stuff" back in some past excursion into music. Since receiving this product, I've been doing a lot better keeping up with the group. Yes, it's been helpful, I no longer freeze up when they capo into a minor key. Easy-peasy now. I've still got a way to go, but it's starting to come together now. Shipping was good, well packed, and protected. If I ever lost mine I would buy it again, and recommend you consider this musician's tool.

My guitar instructor told me about the circle of fifths and how useful it was in song-writing. I wanted a little tool to help me quickly see the chords for the key. There were several options on Amazon, but I'm glad I chose this one. The little decoder is very well made, easy to use, and provides all the information in a clear, readable format. The little book that came with it was a nice bonus.

I have been struggling for years to wrap my mind around playing and writing music. I have a deep love for understanding how and why things work the way that they do. This was the perfect tool for that and made it easy for me to understand. At this point I’ve had this for about a day and I’m already feeling much more confident in my playing and quest for knowledge. Highly recommended for those who want to easily understand what is going on with the music you are playing and writing.

It is a big help learning Circle of Fifths; it also makes transposing easier. Glad I found it !

Perfetto. Istruzioni complete ed esaurienti anche se manca l’italiano ma ben comprensibili. Ben fatto ed utile… un bel giocattolo.

Good product
