What are the ii-V-I chords in all 12 keys?

Around the circle of fourths: C: Dm7–G7–Cmaj7 · F: Gm7–C7–Fmaj7 · B♭: Cm7–F7–B♭maj7 · E♭: Fm7–B♭7–E♭maj7 · A♭: B♭m7–E♭7–A♭maj7 · D♭: E♭m7–A♭7–D♭maj7 · G♭: A♭m7–D♭7–G♭maj7 · B: C♯m7–F♯7–Bmaj7 · E: F♯m7–B7–Emaj7 · A: Bm7–E7–Amaj7 · D: Em7–A7–Dmaj7 · G: Am7–D7–Gmaj7.

In what order should I practice ii-V-I in 12 keys?

Most teachers use the circle of fourths (C, F, B♭, E♭, A♭, D♭, G♭, B, E, A, D, G), because each new key is the next ii-V in real tunes. Learn one key until it is automatic, then add the next; spend extra time on the keys that feel slowest.

Why alternate rootless A and B voicings in a ii-V-I?

Switching between the A form (3–5–7–9) and the B form (7–9–3–5) keeps the left hand in one register: the seventh of each chord falls by a half step to the third of the next, so the voicings move smoothly instead of jumping.

Drill these 12 keys with live feedback

How to practice it in all 12 keys

Pick one key. Play ii-V-I with shell voicings until you don't have to think.
Add the next key around the circle of fourths (C → F → B♭ …). Review the old keys every day.
Once the shells are automatic, switch to rootless A → B. Listen for the seventh falling a half step into the next third.
Time yourself. The keys that feel slowest are the ones to drill tomorrow.

Playing through a chart works, but you can't tell whether you're getting faster. The trainer listens through your MIDI keyboard, times every chord and shows which keys still slow you down.

Shell voicings drop the fifth; rootless voicings drop the root and add the ninth, so a bass player or your right hand covers the root. On the V chord many players swap the fifth for the 13th; once the shapes above are solid, try it.
