Chordii Roman Numeral Music Theory Wheel (White)

Chordii helps musicians visualize chords quickly and confidently. If you’re writing original music, learning chord progressions, teaching students, or exploring new keys, the Roman Numeral Edition helps you understand the why behind the harmony. It’s simple, visual, and surprisingly fun to use.

Chordii brings the whole key to life in one quick spin.
The front shows you every chord in all 15 major keys—so you can instantly see the I, ii, iii, IV, V, vi, and vii° chords for any key without opening a book or Googling charts.

But the magic is on the back! You also get a collection of chord progressions and their moods so you can hear the emotional direction of your song before you even play it.
It’s half left-brain clarity (theory, structure, “how music works”) and half right-brain creativity (feel, vibe, emotion, “what the song wants”).

You learn:
-which chords belong together
-why certain progressions feel bright, sad, tense, or dreamy
-how to move a song from one feeling to another
-how to write confidently in any of the 15 major keys
