Chordii was designed to help entire worship teams stay unified when keys change and plans shift.
See how churches use Chordii →
All Chordii wheels use the same rotating design.
The difference is the information printed on the front and back.
Choose the framework that fits how you think, play, and write:
Traditional theory-based numbering (I, ii, V).
Includes major scale chords, common progressions, and an emotional mood guide.
Best for: musicians trained in classical or traditional theory who prefer Roman numerals for harmonic analysis.
Built for fast transposing and real-world playing (1, 2-, 5).
Available in Major or Minor, and in English or Spanish.
Includes scale chords, practical progressions, and an emotional mood guide.
Best for: worship teams, bands, songwriters, and anyone who wants to play in any key with confidence.
An expanded creative framework built around the major scale.
Features extended chord flavors, movement patterns, and chord mood relationships.
A favorite among bass players who are tired of living on the root note.
Best for: adding lift, color, groove, and intentional motion to your progressions.
Build a “back pocket” of simple chord progressions you can use in any key

Our studio has been looking for a great hands-on way to teach music theory for a while now. When a friend recommended the Chordii, I checked it out and immediately knew it was exactly what we’d been searching for. It’s the perfect tool for helping our students understand key musical concepts. Being able to not just hear the theory but physically engage with it has been a huge win—for them and for us. Thank you, Chordii.

I ordered a few of the Major chordii just to check them out and see if they were useful to students and teachers at our educational music studio. Now, all of our guitar and piano teachers want one. It's a great, well thought-out tool for students launching into songwriting and for music lessons in general.
Great little tool I’ve got my Nashville Minor too. No beating around the bush it show’s exactly were to go on your musical journey when improvising , writing songs , composing. It even shows the Moods in chord progressions it’s a great buy help yourself get a chordii 👍
Great little tool for composers, performers playing all genres of music it gives you insight into modulation, chord progressions you can even see how chords are constructed. Fits into your bag pack or guitar case you can place it on your music stand on your keyboard or even on your coffee table you can take it anywhere you go. I know it wasn't easy to get this project off the ground but this family business has done it they've succeeded in creating a great little accessory for musicians and they value customer satisfaction so support chordii give one to a fellow musician or buy one for yourself. As we say in scots " I'm dead Chuffed ," with my purchase.
I use the Chordii wheel during practice at home and church, and also while leading worship Sunday mornings. This is a great visualization tool to help me memorize the chords in each key and what number each chord is within the key. This is especially useful during spontaneous moments when the music director calls out a number, and I no longer have to guess what chord to play. It’s the ultimate cheat code that I’ve been looking for!

I've already had 2 Chordii's, now I have a set of 3 and a stand. I have a few people at my church who will meet and we will start doing some songwriting. These will provide a great starting point for songwriting. Thank you again! Eric
I got connected with Chordii through Mariah! It's such a blessing. Looking forward to the chordii gear when every it's released. Thanks
Great tool to understand chord patterns, chord voicing, and writing songs or song parts. A quality product for sure!

Excelente herramienta, me ayudará bastante a tener un mejor aprendizaje y de manera más efectiva, pues soy muy fan de lo visual y esto definitivamente cumple su función 💪🔥
Very helpful in many ways. I am enjoying getting to know it.

I’m so excited to try this out in my own songwriting but also to help my private music students learn the number system!
So happy I purchased it, Thanks so much
Been playing for years by ear and key sigs. Cool to put numbers to the process. The thingamajig you wished they made sooner..
I was one of the first international orders from Andrew and the team at Chordii. It’s a brilliantly simplistic product that’s well designed and is of a really high quality. It’s really helped me already. Much prefer the tactile nature of this device rather than the digital alternatives. Thanks team Chordii!
This is a great tool. My only question is: where was this about 15 years ago? I wrote songs that were all over the place musically, not knowing anything about music theory. Love this tool! 🎸
I know very little about music theory outside of a vague understanding, but immediately after getting a Chordii I was able to use it to easily write a cool, moody guitar riff. I’m excited to see how else it can benefit my music writing!
The chords are there to use and Major Mimor and sevenths are fantastic. If you want key of A it is all there as is all 12 notes with number system
Very genius product for changing a key change in a song.
Very nice and handy
Great product. Great ordering experience.
great, I ll start to use it!
Great, haven’t used it yet
Had to have this! Andrew and the team at Chordii are the best to work with and my team loves this! It’s been such a helpful tool. Highly highly recommend.
Worship Team loves the tool!!! Everyone that plays an instrument took one!!! Really grateful for an amazing product!!! Also, a great friendly and helpful company!!! (Glad the kids got doughnuts!!!)
It has given me key to open a new door with guitar. Thank you .
Such a simple to use, well-made tool that is going to be so helpful for our volunteer musicians at church.
Well, usually the Nashville number system uses Roman numerals. Capital Roman numerals for major chords, lowercase Roman numerals for minor chords. This is what I was expecting. And I thought I had seen this in the catalog on the vendors website and specified it. But maybe it was my miscommunication. Anyway, The vendor was nice enough to ship out the product prior to receiving payment based on my immediate need and trust we had developed in our correspondence. There for decided I would not return the items but rather pass them on to my music students and explain the translation between Arabic numbers with minus signs for minor chords instead of the usual Roman numeral nomenclature. We are satisfied with the product, just had a slip up in communication.
The product is better than expected. Very professional product or order process. Great job!
Helping me to learn Nashville numbers…
The kids want more pizza.
Just from what I saw on Sunday Sounds I was able to use it on Sunday for the chord progressions. Looking forward to doing more with it!
I wish the keys were in alphabetical order instead of circle of 5th order.
The tool is very helpful for helping with quick key changes and finding the appropriate triads to play during worship.
Very easy to read.
It takes away the burden of remembering where to go. Really helps with keeping the flow going.
I ordered these for the Worship Team at my church. They seem to be excellent quality, and Andrew was incredible to work with. One of the best ordering experiences I've ever had.
