Chordii
All Chordii wheels use the same rotating design—the difference is in the info on the front and back. Choose the version that fits how you think, play, and write:
Roman & Nashville
Same tool, two different number systems. Both include:
- Major scale chords (maj / min / dim)
- Common chord progressions
- Emotional mood guide
Tip: Nashville is perfect if you’re used to the Nashville Number System. Roman numerals are great if you’ve studied traditional theory. Both show the same core info.
Nashville+
Takes it further with more detail.
- Front: extended chord flavors + a new way to spot chord tones (see how it works)
- Back: instead of progressions, you’ll find each chord’s mood and how it moves in a song
Perfect for adding color, tension, or soul to your songwriting.
Minor Versions
A brand-new way to explore music through the natural minor scale.
- Minor scale chords (min / dim / maj)
- Progressions and moods unique to minor keys
- Unlock darker, more emotional tones for your writing
Spanish Editions
Nashville Major and Minor are also available in Español—making Chordii more accessible for classrooms, worship teams, and musicians across the world.

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.

More Than a Tool—It's a Creative Shortcut
