What Is a II-V-I Progression on Guitar?

The II-V-I is a recurring progression in jazz standards and tonal harmony. On guitar, understanding its chord functions and guide-tone movement makes it easier to connect voicings, hear the resolution and build improvisation exercises from a real chart.

Core idea

Tension that wants to resolve home

A II-V-I is three chords built on the second, fifth and first degrees of a key. The II sets up the V, the V creates tension, and the I provides the resolution. In C major, the chord symbols are Dm7 – G7 – Cmaj7.

Dm7II G7V Cmaj7I

What II-V-I actually means

The Roman numerals refer to scale degrees, not fixed chord names. In this article, II-V-I names the second, fifth and first degrees in uppercase for readability; the chord symbols show their actual qualities. In C major, those seventh chords are Dm7, G7 and Cmaj7.

II — Dm7

Minor seventh chord on the second degree. Notes: D–F–A–C. It prepares the dominant.

V — G7

Dominant seventh chord on the fifth degree. Notes: G–B–D–F. Its third and seventh form the tritone B–F.

I — Cmaj7

Major seventh chord on the first degree. Notes: C–E–G–B. It provides the tonic resolution.

Because the numbers are relative a II-V-I in F major is Gm7 – C7 – Fmaj7, and in G major it is Am7 – D7 – Gmaj7. Learn the movement, then rebuild it from the second, fifth and first degrees of another key.

Why the progression works

The dominant chord drives the resolution. In G7, B is the leading tone of C and normally resolves upward to C; F, the chordal seventh, commonly resolves downward to E. These two half-step movements lead directly into notes of Cmaj7.

Dm7 prepares G7 and shares the note F with it, while its seventh C can descend to B, the third of G7. The roots move by ascending fourth or descending fifth: D to G, then G to C. This combination of functional bass movement and small inner-voice motion helps explain why the progression is so useful in tonal jazz harmony.

Play a II-V-I on the fretboard

You do not need six-note grips. A practical starting point is a compact shell voicing containing the root, third and seventh. Those notes establish the chord function while leaving room for a melody or another instrument. Here is one position in C major.

      Dm7        G7        Cmaj7
e|----------|----------|----------|
B|----------|----------|----------|
G|---5------|---4------|---4------|
D|---3------|---3------|---2------|
A|---5------|----------|---3------|
E|----------|---3------|----------|

The Dm7 voicing contains D–F–C, G7 contains G–F–B, and Cmaj7 contains C–E–B. F stays in place from Dm7 to G7 while C descends to B; then B stays in place while F descends to E. This is voice leading you can both hear and see on adjacent strings.

The minor II-V-I

Minor keys use a related progression with different chord qualities. In A minor, a basic form is Bm7♭5 – E7 – Am: half-diminished II, dominant V and minor tonic I. The B half-diminished chord contains B–D–F–A. E7 introduces G♯, the leading tone that resolves to A. Jazz arrangements may add alterations to E7, but those colours are choices rather than requirements.

What to play over a II-V-I

For the major example Dm7–G7–Cmaj7, all chord tones belong to C major, so the C major scale is a practical first framework. To make the line describe the progression more clearly, aim for the third or seventh when each chord arrives, then connect those targets with nearby scale notes, chromatic approaches or arpeggio notes.

Those thirds and sevenths are the guide tones. Connecting them is a foundational way to hear the chord changes — see Guide Tones on Guitar. For the broader habit of aiming at chord tones on strong beats, read How to Use Chord Tones in Guitar Solos, and for scale choices in context, see What Scales Should You Play Over a Chord Progression?

Try this Play only the third and seventh of each chord while the progression loops. Listen to the common tones and half-step resolutions before adding a full scale or longer phrase.

How to spot it in real songs

Look for a minor seventh chord followed by a dominant seventh whose root is a fourth higher, then a tonic chord another fourth higher. Do not rely on chord quality alone: confirm the destination and key context, because the same chord can serve another function. Standards such as Autumn Leaves and Fly Me to the Moon contain II-V movement and related functional cycles worth analysing measure by measure.

Map a II-V-I in GuitarHarmonyLab

Recognising a II-V-I on paper is one step; locating its guide tones on the fretboard is another. Enter the progression in GuitarHarmonyLab, verify the tonal centre and chord functions, then display the chord tones or guide tones in the position you want to practise. If the source is a clear photo or PDF, review the recognised chart before using the analysis.

Practice exercise Enter Dm7 – G7 – Cmaj7, display the guide tones, and follow how the seventh of each chord descends by a half step into the third of the next. Save that movement as a Practice Card, then repeat the exercise in another key.

Frequently asked questions

What are the chords in a II-V-I in C major?

The seventh chords are Dm7, G7 and Cmaj7. They are built on the second, fifth and first degrees of the C major scale.

Can I use one scale over a major II-V-I?

C major covers the diatonic notes of Dm7–G7–Cmaj7. It is a useful starting framework, but targeting each chord’s third and seventh makes the harmonic movement clearer.

How should I practise a II-V-I on guitar?

Begin with compact shell voicings, then play only the thirds and sevenths. Connect the guide tones, add nearby scale notes and repeat the same task in another key.
