Most circle of fifths are confusing and cluttered
Decoder Circle of Fifths shows you the key signatures for each key by visually highlighting which notes are flat or sharp AND shows you where they appear in each key's major scale.
We even added in a little extra - the Quick Chords, so that you can see how chords are built up from the notes. This tool simplifies the theory so that you can focus on the fun part -Playing More

Let customers speak for us
from 98 reviewsOrdered the Decoder after seeing Sean Daniels review. It came very fast and it’s super informative to finding all chords in any key! Great product and I highly recommend it! Thank you!
I found out about the Decoder through Sean Daniel’s YouTube-video and ordered it directly. Although I’m a Swede and still living there, the product came relatively fast.
And I really love the product and the following book! So much fun and an excellent way of diving in to music theory! Thanks a lot for a truly brilliant product. I’m now spreading the word about you!!!

This is a great teaching aid for beginners and even a fantastic tool for writing when you've hit a wall. This should be handed out in every music class, everywhere!
Thanks for bringing this to market the way it should be.
Super handy tool for developing understanding of music theory. Really well designed, useful for building knowledge of connections between chords in each key and the notes making up each chord. Very helpful.
Great tool. Thanks for making things a little simpler.
While the Circle of Fifths is a useful tool on its own, this Decoder takes everything about the Circle of Fifths to a whole new level. It makes understanding relationships much easier and quicker to sort out.
Additionally, I have a form of dyslexia that makes it difficult for me to see things right away in a cluttered space. The Decoder's format automatically eliminates this visual clutter and I can immediately see that which is most important. THAT makes me smile.
Simple, clean, effective. I like this tool.
Very useful in learning Circle of Fifths. The sellers email communications were outstanding! Will use for years!
Absolutely amazing. It made my day/weekend/ week.
I've been playing guitar on and off for over 45 years, but my theory is shockingly limited if I'm honest. This little tool is such a fun way of getting you versed with the circle of fifths, which is a fairly fundamental bit of theory and song composition. It's nicely put together and eases learning of what can be a dry subject. Noisy Clan - if you have any more of this in the pipeline count me in!
I love my Wee Stand. It’s portable, easy to use, and can be stabilized easily if you’re using it outdoors. I bought mine via the original Kickstarter campaign and when I had a problem recently, customer service made sure it was solved by getting me a replacement. Thanks to all for standing behind a great product.
I'm close to 30 & have been a guitarist for 13 years, and this tool is a life saver. I struggle to learn when presented with lots of information at once due to brain fog, but with this tool and well explained information in the book, you only see what is relevant, and if you slide to another key, the pieces of information you don't need are hidden. 10/10
Simple to use but effective for song writing. Works great.
This is an excellent well thought out learning tool for musicians . I play guitar and the circle of fifths can sometimes seem a bit daunting , but this tool really helps with understanding it though and is a handy size. Fully recommended.
1st, I’d have paid good money just for the cool box! 😁
Watching the video is very important. A good chance I’d have broken something proceeding in my normal seat-of-the-pants method.
iPad sits a bit tilted because of the fact that right side fits within the left when folded but I’ll adjust, or shim if I don’t.
As delicate as it feels, I’m confident it will hold up in anything short of gale winds. I’ll probably tend to use it for seated playing more than standing. Only time will tell if its clever engineering holds up. Hope it does because its going to be my daily carry.
It really does help with rhythm ideas and learning some music theory is always a good thing
