The ii–V–I (also called the 2-5-1 chord progression) is the foundation of jazz piano harmony.

If you want to truly understand jazz harmony, chord progressions, and improvisation, learning the ii–V–I in all 12 keys is one of the most important milestones.

Here is the ii-V-I in C major:

In this lesson, you’ll learn:

If you master this, you’ll build a foundation for virtually everything else in jazz.

What's the #1 goal for new Jazz piano students?

I would say it's this:

Learn the 2-5-1 through all 12 keys.

Once you can do this you'll have a solid foundation for everything else.

But how do you actually practice something in all 12 keys?

What does it look like to "take it through all 12 keys"?

Today I'll show you three patterns.

But first – if you want to learn jazz piano properly from the ground up — without missing key steps — start here.

What Is a 2-5-1 Chord Progression?

The 2-5-1 chord progression (written as ii–V–I) is the most common chord progression in jazz.

In the key of C major, the progression is:

• Dm7 → G7 → Cmaj7

Almost all jazz standards contain the 2-5-1 progressions in some form.

Learning to play the 2-5-1 in all 12 keys will prepare you for playing new jazz songs. Your left hand will already know how to play the 2-5-1 in every key, and you'll be able to predict which chord is coming next.

How do you voice a ii-V-I?

There's many ways you can voice a ii-V-I in jazz.

There's shell voicings, rootless voicings, and more.

However, I suggest every jazz pianist start with this voicing pattern:

Notice the V7 chord is played in 2nd inversion (D F G B). This creates smooth voice-leading, and your hand doesn't have to jump anywhere.

How to Practice the ii–V–I in All 12 Keys

You'll often hear a teacher say "practice this through all 12 keys".

But usually, they don't tell you how to do that.

First of all – you could just go through the keys at random.

However, there are some more elegant patterns that musicians prefer to use.

Let me show you three main patterns you can use – to practice the ii-V-I through all 12 keys.

Pattern 1 (descend in half-steps)

Play the 2-5-1 and descend in half-steps through all 12 keys:

Dm7 → G7 → C maj 7 (key of C major)
C#m7 → F#7 → B maj 7 (key of B major)
Cm7 → F7 → Bb maj 7
Bm7 → E7 → A maj 7
Bbm7 → Eb7 → Ab maj 7
Am7 → D7 → G maj 7
Abm7 → Db7 → Gb maj 7
Gm7 → C7 → F maj 7
F#m7 → B7 → E maj 7
Fm7 → Bb7 → Eb maj 7
Em7 → A7 → D maj 7
Ebm7 → Ab7 → Db maj 7
Dm7 → G7 → C maj 7 (ends back in C major)

(This pattern gives you a nice sounding modulation every time you shift to the next ii-V-I).

Pattern 2 (descend in 5ths).

Play the 2-5-1 and descend in 5ths through all 12 keys:

Dm7 → G7 → C maj 7 (key of C major)
Gm7 → C7 → F maj 7 (key of F major)
Cm7 → F7 → Bb maj 7 (key of Bb major)
Fm7 → Bb7 → Eb maj 7
Bbm7 → Eb7 → Ab maj 7
Ebm7 → Ab7 → Db maj 7
Abm7 → Db7 → Gb maj 7
C#m7 → F#7 → B maj 7 (re-spelt from flats to sharps)
F#m7 → B7 → E maj 7
Bm7 → E7 → A maj 7
Em7 → A7 → D maj 7
Am7 → D7 → G maj 7
Dm7 → G7 → C maj 7

Pros: Easy to remember (down a 5th every time).

Cons: Your hands have to change position every time.

Pattern 3 (my personal favorite)

Play the 2-5-1 and descend in whole-steps through the first six keys:

Dm7 → G7 → C maj 7 (key of C major)
Cm7 → F7 → Bb maj 7 (key of Bb major)
Bbm7 → Eb7 → Ab maj 7
Abm7 → Db7 → Gb maj 7
F#m7 → B7 → E maj 7
Dm7 → G7 → C maj 7 (back to C major)

Next, count up a half-step and play through the six remaining keys:

C#m7 → F#7 → B maj 7 (key of B major)
Bm7 → E7 → A maj 7 (key of A major)
Am7 → D7 → G maj 7
Gm7 → C7 → F maj 7
Fm7 → Bb7 → Eb maj 7
Ebm7 → Ab7 → Db maj 7

This is my favorite '12 key pattern' because my hands can stay in the same place. There's no jumping around.

All I have to do is jump up an octave once - whenever it sounds too low or muddy (depending on what I'm practicing).

If you're not sure which pattern to use - use this one.

What is the Minor ii-V-i?

There is also a minor ii-V-i in jazz.

Most ii-V-Is in jazz are the major type (roughly 90%).

However, you still encounter the minor ii-V-i (roughly 10% of ii-V-is).

The minor ii-V-i is built from the melodic minor scale:

So in C melodic minor scale, you would build a ii chord from D, V chord from G, and i chord from C.

All three chords are 7th chords – so build from the notes of C melodic minor scale.

KEY POINT:

However – the final i chord of a minor ii-V-i is often changed to a minor 7 chord instead.

Why?

It sounds less dramatic, and more causal. And in the middle of a jazz song, a minor 7 chord is preferred by composers.

However – it's good to know that the 'original' minor ii-V-i in jazz theory, is correctly built from the melodic minor scale.

Minor ii–V–I Progressions in All 12 Keys

Yes - all of these patterns will work for the minor 2-5-1 as well.

Same root notes. Just change the types of 7th chord.

Here's the minor 2-5-1 using pattern #3:

Dm7b5 → G7 → Cm7 (in C minor)
Cm7b5 → F7 → Bbm7 (in Bb minor)
Bbm7b5 → Eb7 → Abm7
Abm7b5 → Db7 → Gbm7
F#m7b5 → B7 → Em7
Em7b5 → A7 → Dm7
Dm7b5 → G7 → Cm7

Count up a half-step for the remaining six keys:

C#m7b5 → F#7 → B min 7 (key of B minor)
Bm7b5 → E7 → A min 7 (key of A minor)
Am7b5 → D7 → G min 7
Gm7b5 → C7 → F min 7
Fm7b5 → Bb7 → Eb min 7
Ebm7b5 → Ab7 → Db min 7.
C#m7b5 → F#7 → B min 7

Your challenge:

If you haven't yet learned to play the 2-5-1 in all 12 keys, this is your #1 goal.

Choose one of the patterns above (I recommend #3), and spend the next two weeks mastering the major 2-5-1.

Get to the point where you can play the 2-5-1 through all 12 keys, note-perfectly, three times in a row.

Simple chord voicings is all you need.

Once you understand the ii–V–I, the next step is learning which chord voicings to use:

Summary

• Learn one ii–V–I pattern
• Practice all 12 keys daily
• Master major first
• Add minor ii–V–I next
• Apply chord voicings
