Extended Chords on Guitar: 11ths, 13ths, and How to Actually Play Them

You already know that 7th chords (Cmaj7, Am7, G7) add one note beyond the basic triad. Extended chords take this further: 9th chords add another note, 11th chords add one more, and 13th chords stack another on top of that. A theoretical 13th chord includes seven notes - which is all seven notes of the major scale simultaneously.

On guitar, with only six strings, you can’t play all seven notes. Extended chords on guitar are always abbreviated voicings - strategic selections of the most harmonically essential notes. Learning which notes to keep and which to omit is the practical skill of extended chord playing.

Understanding the Extension Stack

Built from a root note, the full extension stack works like this:

Triad: Root - 3rd - 5th
7th chord: Root - 3rd - 5th - 7th
9th chord: Root - 3rd - 5th - 7th - 9th
11th chord: Root - 3rd - 5th - 7th - 9th - 11th
13th chord: Root - 3rd - 5th - 7th - 9th - 11th - 13th

On guitar, when you see a “13th chord,” you don’t play all seven notes. Instead, you play the:

Root (sometimes omitted when a bassist handles it)
3rd (essential - defines major or minor)
7th (essential - defines the extension sound)
13th (the featured extension note)

The 5th, 9th, and 11th are often omitted. This compression is what makes extended chords guitaristically playable.

The Key Principle: Which Notes Matter

For any extended chord, the notes that carry harmonic identity are:

The 3rd - tells you if it’s major or minor
The 7th - tells you if it’s dominant, major 7th, or minor 7th quality
The extension itself (9th, 11th, or 13th) - the “color” note

Everything else (the root, 5th, and in-between extensions) can often be dropped.

This is why a guitarist can play a Cmaj13 chord that sounds completely right while only fretting 4 notes - you’re hitting the essential harmonic content.

9th Chords: The First Level Extension

Before going to 11ths and 13ths, let’s briefly cover 9ths as the foundation:

Dominant 9th (The Core Funk/Jazz Chord)

E9 (root on 6th string, 7th fret):

e|---7---|
B|---7---|
G|---6---|
D|---7---|
A|---x---|
E|---7---|

This is the chord that drives virtually all funk rhythm guitar and jazz comping.

Cmaj9:

e|---0---|
B|---3---|
G|---4---|
D|---2---|
A|---3---|
E|---x---|

Lush, sophisticated major 9th sound.

11th Chords on Guitar

The 11th is the same pitch as the 4th, one octave up. On a major chord, the 11th creates tension against the major 3rd (the interval between 3 and 4 is only a half step in major scales). For this reason:

Dominant 11th chords work well (the flat 7th softens the 3rd-11th clash)
Suspended chords (sus4 = sus11) replace the 3rd entirely with the 11th
Minor 11th chords sound beautiful (minor 3rd has less clash with the 11th)

Dominant 11th

For a dominant 11th, omit the major 3rd to avoid the harsh clash. What remains: Root, 7th, 11th (4th), and optionally the 9th.

G11 voicing:

e|---3---|
B|---3---|
G|---0---|
D|---0---|
A|---x---|
E|---3---|

This is essentially a Gsus4 with a 7th - which is what a dominant 11th sounds like in practice.

Minor 11th

Minor 11th chords are gorgeous. The minor 3rd and the 11th create a perfect 4th interval between them, which is consonant and open-sounding.

Dm11:

e|---1---|
B|---1---|
G|---2---|
D|---0---|
A|---x---|
E|---x---|

Or a lusher voicing:

e|---0---|
B|---1---|
G|---2---|
D|---0---|
A|---5---|
E|---x---|

Dm11 is used constantly in soul, R&B, and neo-soul guitar. The sound is deep and emotionally rich.

Sharp 11 (Lydian Sound)

The #11 (augmented 11th) is the Lydian mode’s signature note. A Maj7#11 chord has an ethereal, floating quality:

Cmaj7#11:

e|---0---|
B|---3---|
G|---4---|
D|---2---|
A|---x---|
E|---x---|

That #11 (F#) gives the chord its distinctive floating quality - heard throughout jazz and progressive rock.

13th Chords on Guitar

The 13th is the same pitch as the 6th, one octave up. 13th chords are common in jazz, soul, and funk.

Dominant 13th (The Nile Rodgers Chord)

The classic funk-jazz 13th chord voicing:

G13:

e|---5---|
B|---5---|
G|---5---|
D|---5---|
A|---5---|
E|---3---|

This shape is moveable - root on the 6th string. Slide it to make any dominant 13th.

The key: 3rd, flat 7th, and 13th (6th) are all present. Root and 5th are there too. The 9th and 11th are omitted.

E13:

e|---0---|
B|---3---|
G|---1---|
D|---0---|
A|---2---|
E|---0---|

Minor 13th (Deep Soul Sound)

Minor 13th chords have a profound, weighty depth - a minor chord with added harmonic color.

Am13:

e|---5---|
B|---5---|
G|---5---|
D|---7---|
A|---5---|
E|---x---|

Or in open position:

e|---0---|
B|---1---|
G|---2---|
D|---2---|
A|---0---|
E|---x---|

The 13th (F# in Am13) adds a jazz-inflected color to the minor chord. This sound is central to neo-soul and jazz guitar.

Major 13th

Cmaj13:

e|---0---|
B|---1---|
G|---0---|
D|---2---|
A|---3---|
E|---x---|

Or voiced as:

e|---3---|
B|---3---|
G|---4---|
D|---5---|
A|---3---|
E|---x---|

The major 13th chord includes the major 7th and the major 6th (13th) together - a lush, jazz-flavored major chord.

When to Use Extended Chords

Jazz and Bossa Nova

Extended chords are expected in jazz contexts. Virtually every chord in a jazz standard should have at least a 7th, and often 9ths and 13ths add color. Use them freely.

Soul and R&B

Dominant 9ths and 13ths are the backbone of soul and R&B harmony. Minor 9ths and 11ths also appear constantly. Listen to Stevie Wonder, Marvin Gaye, and D’Angelo for reference.

Funk

Dominant 9ths are the primary chord. 13ths appear in more sophisticated funk arrangements. The cleaner the tone, the better the extended chord qualities come through.

Pop and Rock

Use extended chords sparingly in pop and rock for moments of sophistication. A verse in plain major/minor chords followed by a bridge with a maj9 chord creates a beautiful contrast.

Chord Voicing Strategy: Building Your Own Extended Chords

When you encounter an extended chord you don’t know, build it systematically:

Start with the 7th chord voicing (which you know)
Identify which string is free or which note you can add
Find the extension note on an available string
Adjust the voicing to include both the essential notes (3rd, 7th) and the extension

This method lets you create custom voicings rather than memorizing every possible extended chord.

Common Mistakes

1. Playing too many notes. Extended chords don’t need all seven tones. Keep the 3rd, 7th, and extension. Omit the 5th and intermediate extensions freely.

2. Forgetting the 3rd. Without the 3rd, the chord loses its major/minor identity. Never omit the 3rd when building extended chord voicings.

3. Using extended chords everywhere. Extended chords have maximum impact when used alongside simpler triads. All 13ths all the time loses the sense of color contrast.

4. Not knowing the component intervals. If you don’t know that a 13th chord contains a 7th, you might try to play a 13th chord voicing that omits the 7th - and it won’t sound right.

Conclusion

Extended chords are the harmonic vocabulary of sophisticated music. They’re not inherently complex to play - many require the same number of fretted notes as basic triads - but they require understanding which notes to include and why. Start with dominant 9ths (essential for funk and jazz), then explore minor 11ths and dominant 13ths. Apply them in musical contexts where they make sense. Extended chords don’t make music better by themselves - but used with intention and taste, they add a harmonic depth that simpler chords can’t provide.

FAQ

Are 11th and 13th chords hard to play?

The voicings themselves aren’t necessarily harder than 7th chords - you’re playing 4-6 strings with 3-4 fretted notes. The challenge is understanding which notes to include. Once you know the essential notes (3rd, 7th, extension), you can build playable voicings efficiently.

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

The 13th chord includes a 7th, while a 6th chord (add6) doesn’t. Cmaj13 contains C, E, G, B, D (9th), F (11th), A (13th). C6 contains C, E, G, A. The presence of the 7th is what makes it an extended chord versus a simpler added note chord.

When should I use extended chords in my playing?

Use extended chords when you want to add harmonic sophistication - in jazz, soul, funk, and R&B contexts especially. In rock and pop, use them selectively for moments of lushness or contrast. Let the style and context guide your choices.
