13th Chords on Guitar: Extended Harmony Beyond the 9th

In short: Learn how to play 13th chords on guitar. Understand the theory, discover playable voicings for dominant 13th and major 13th, and find out how to use them in jazz, blues, and neo-soul.

Most guitarists know about 7th chords and have encountered 9th chords. But extended harmony goes further - all the way to 11ths and 13ths. A 13th chord is the most complete expression of a single scale as a chord: it stacks notes from the root up through the 13th scale degree.

The good news: you don’t need to play all those notes. On guitar, practical 13th chord voicings use just three to five carefully chosen notes that convey the full harmonic character.

What Is a 13th Chord?

In theory, a 13th chord contains: Root - 3rd - 5th - 7th - 9th - 11th - 13th. That’s seven notes - one for every scale degree. Obviously, on a six-string guitar with four fingers, you can’t play all of them.

What you do instead: keep the most harmonically important notes and omit the rest. For a dominant 13th chord, the essential tones are:

  • Root (1)
  • Major 3rd (3)
  • Minor 7th (b7)
  • Major 13th (6 or 13)

The 5th and 9th are usually omitted in practical voicings. The 11th is typically omitted in dominant 13 chords (it clashes with the major 3rd in most contexts).

Types of 13th Chords

Dominant 13th (13 or dom13)

The most common 13th chord. Built on the 5th scale degree (or anywhere you want dominant function). The dominant 13th contains: Root, Major 3rd, Minor 7th, Major 13th.

Formula: 1 - 3 - b7 - 13

The 13th is the same pitch as the major 6th. In jazz and blues, when someone says “13 chord,” they almost always mean the dominant 13th.

Major 13th (maj13)

A major 7th chord with the 9th and 13th added. Brighter and more complex than the dominant 13th.

Formula: 1 - 3 - 5 - 7 - 9 - 13

Used extensively in jazz and neo-soul for lush, warm major chord sounds.

Minor 13th (m13)

A minor chord with the minor 7th, 9th, and 13th. The 13th is major (natural 6th), which gives a bright, floating quality to the minor chord.

Less common but beautiful in neo-soul and jazz balladry.

Playable 13th Voicings on Guitar

On guitar, the most practical 13th shapes are usually shell voicings. That means you keep the notes that define the sound and let go of expendable tones like the 5th or 9th when necessary.

G13 Shell Voicing (3x345x)

G13 chord diagram

This is a strong first dominant 13th to learn. It gives you the root, major 3rd, minor 7th, and 13th all in one compact grip. Those are the exact colors that make a G13 sound like more than a plain G7.

Because the 5th is optional in many jazz, soul, and funk settings, this voicing stays compact without sounding incomplete. It is especially useful when you want a tight chord stab rather than a huge open strum.

E13 Open Voicing (020120)

E13 chord diagram

E13 is one of the friendliest 13th sounds in standard tuning because the open low and high E strings make the harmony ring immediately. In this shape you hear the root, major 3rd, minor 7th, 5th, and 13th.

This voicing works beautifully before an A major or Amaj7 chord. The open-string sustain also makes it a great bridge between theory practice and real musical playing because the color is obvious as soon as you strum it.

Gmaj13 Shell Voicing (3x445x)

Gmaj13 chord diagram

A major 13th swaps the dominant 7th for a major 7th, which changes the emotional effect completely. Instead of sounding bluesy or tense, it sounds resolved, rich, and polished.

This Gmaj13 shell contains the root, major 7th, major 3rd, and 13th. It is the kind of voicing you can use at the end of a progression when you want the harmony to feel settled but still colorful.

Major 13th Voicings

The major 13th contains the major 7th plus the 13th. In practice, guitarists rarely try to include every possible extension. The better goal is to voice the chord so the listener clearly hears:

  • the root
  • the major 3rd
  • the major 7th
  • the 13th

If those tones are present, the chord color comes across clearly even if the 5th and 9th are omitted.

When to Use 13th Chords

Dominant 13th: The Resolution Target

In a ii-V-I, the V chord is often played as a 13th: Dm7 - G13 - Cmaj7. The 13th (E) adds brightness to the G dominant and creates smooth voice leading to the E in Cmaj7.

Replacing Dominant 7th Chords

Any time you’d play a dominant 7th chord (G7, A7, E7), try the 13th version instead. The 13th adds a shimmer without fundamentally changing the harmonic function.

Major 13th for Lush Resolution

In a progression that lands on a I chord, use a major 13th for the final resolution. Instead of landing on Gmaj7, land on Gmaj13. The extra resonance of the 13th (E) creates a brighter, more open resolution.

Funk and Soul Vamps

Two-chord vamps using dominant 13th chords are a staple of funk and soul. E13 alternating with A13 creates a rich, complex funk rhythm figure.

Practice Routine for 13th Chords

Week 1: Learn the E13 voicing above. Play it in context - put it before an A major chord and hear the dominant tension resolve.

Week 2: Learn a moveable dominant 13th shape (root on 6th string). Move it to G13, A13, D13.

Week 3: Use a dominant 13th in a ii-V-I: Am7 - E13 - Amaj7. Listen to how the 13th enriches the progression.

Week 4: Try major 13th on your I chord resolutions. Compare Gmaj7 to Gmaj13. Notice the added shimmer.

Conclusion

13th chords bring the full richness of extended harmony to your guitar playing. The dominant 13th is one of the most sophisticated and beautiful sounds in jazz and soul - a dominant chord elevated by the added 13th note. The key to making them playable is choosing a few essential tones (root, 3rd, 7th, 13th) and omitting the rest. Start with the E13 voicing, internalize its sound, then explore the shape in other keys. Extended harmony opens doors that plain 7th chords can’t reach.

FAQ

What is the difference between a 7th chord and a 13th chord?

A 7th chord has root, 3rd, 5th, and 7th - four notes. A 13th chord adds the 9th, 11th, and 13th on top, though on guitar you typically voice only the most important of these. The 13th adds the 6th scale degree on top of the dominant structure.

Can beginners play 13th chords?

Some 13th voicings are actually quite accessible - particularly ones that use open strings. The E13 shape with open strings is manageable for anyone who can play an E7. The challenge is understanding when and why to use them.

What’s the difference between a 13th chord and a 6th chord?

A 6th chord (like G6: G-B-D-E) contains the major 6th but no 7th. A 13th chord contains the minor 7th AND the 13th (which is the same pitch as the 6th). The 7th is what distinguishes them harmonically.

People Also Ask

What notes are in a 13th chord? A full 13th chord contains: root, major 3rd, perfect 5th, dominant 7th (b7), major 9th, perfect 11th, and major 13th. On guitar, voicings typically include root, 3rd, b7, and 13th as the minimum essential tones.

What is G13 chord on guitar? G13 is a dominant 13th chord with G as the root. Its essential notes are G (root), B (major 3rd), F (minor 7th), and E (13th). Various guitar voicings emphasize these notes while omitting the 5th and 9th.

When do you use 13th chords? Use 13th chords as a richer substitute for dominant 7th chords (especially in ii-V-I progressions), in jazz and neo-soul comping, and as funky vamp chords in R&B contexts.
