I've recently discovered and am actively using the decoders for piano and guitar along with the circle of 5ths and various other cheat sheets - all wonderful, helpful, thought provoking and of really good quality to help me with new songs and general creativity.

First of all, I’m not a big review writer. But in this case, I really want to leave a review. When I saw the circle of fifth decoder and the court compass for the first time I ordered them right away and both products are brilliant While I have been learning about music theory and teaching myself to play the piano for the past 4 years I wish I would’ve known about these two “tools” earlier. They are simple and easy to use and very well-made. Great value for money! Thank you. It’s great to see innovation making an impact.

Wow the Noisy Clan has knocked this out of the park! These are singularly the highest quality theory products I've ever touched. Well thought out, intuitive, straightforward and simple to understand. The Compass is a must have for practice and the books are perfect. I couldn't be happier. There is clearly a tremendous amount of thought and creativity that went into this. I thank you for your efforts and encourage everyone to try this out. You won't be disappointed.

Great and easy to use

I love this product. I like the way it slides side to side. I have been trying to make my own over the past few years listening to other musicians. I have not had anything made this good. Well pleased thanks
