B11 Chord on Guitar
B11 = B – D# – F# – A – C# – E (Root, Major 3rd, Perfect 5th, Minor 7th, Major 9th, Perfect 11th)
B11 is the point where a dominant chord's stacked thirds start to genuinely strain a six-string instrument, and guitarists solve it the way jazz pianists do — dropping the major third entirely, since a natural eleventh sitting a half step above the third would clash. The result, on this seventh-fret barre, is a lean voicing that looks closer to a 7sus4 shape than to a fully stacked chord.
In full theory, B11 draws on B, D#, F#, A, C#, E, but the practical guitar voicing keeps essentially root, seventh, and eleventh — B, A, E — letting the fourth stand in for where the third would otherwise sit. As an extended dominant, B11 still pulls toward E major the way B9 or plain B7 does, but with a hazier, more suspended color that avoids landing squarely on major or minor.

How to Practice It
Because this voicing is so close in shape to a 7sus4, it's worth playing B7sus4 and B11 back to back to notice how similar they sound with the third removed. Listen for the eleventh's slightly floating, unresolved character compared to a plain dominant seventh in the same spot.
Common Progressions
- B11 – E (V11 – I, a hazier resolution than plain V – I)
- Amaj7 – B11 – E (a suspended-feeling turnaround into E major)
- B11 – B7 – E (contrasting the suspended and resolved dominant colors)
- E – B11 – E (I – V11 – I as a static vamp)
FAQ
- Why does the guitar version of B11 leave out the third?
- The natural eleventh sits only a half step above the major third, and sounding both together produces a harsh clash, so guitarists simply omit the third and let the eleventh take its place.
- Is B11 the same as B7sus4?
- They're close cousins — both typically drop the third and feature the fourth prominently — but B11 theoretically implies the full stack up through the ninth as well.
- What key does B11 pull toward?
- The same as B7 or B9 — E major — since it's still fundamentally a dominant chord built on B, just with a hazier color thanks to the missing third.
- Why is B11 less common in simple pop and folk writing?
- Its ambiguous, suspended character doesn't provide the strong pull that simpler songwriting often wants, so it shows up more in jazz, funk, and modal writing.
- Does the fingering for B11 change much from B7?
- It largely swaps which finger frets which string rather than adding significant new stretch, since both are lean voicings built from the same barre position.
- Can B11 be used as a substitute for a plain B minor sound?
- Informally, yes — without a clear major third present, B11 doesn't commit strongly to major, so a player can use it to imply ambiguity between B major and B minor.
- How does B11 compare to B13 in terms of density?
- B11 is the leaner of the two, since standard voicings of B13 often reintroduce the third alongside the thirteenth, while B11's identity rests on the third's absence.
- Can B11 be played with an A-shape barre instead?
- Not comfortably — the reduced voicing is already a stretch in E-shape form, and squeezing it into an A-shape barre near the second fret rarely improves on the seventh-fret version.
- Why does B11 sound closer to a suspended chord than a full jazz extension?
- Because the practical voicing drops the third in favor of the fourth, listeners mostly hear a suspended color rather than the fuller stacked harmony the chord's name implies.
- Is B11 easy to mistake for plain B7 by ear?
- It can be at a glance, since both are dominant chords on the same root, but B11's added fourth gives it a distinctly hazier quality once a listener knows to listen for the suspended color.
- Do arrangers write out the full 11-chord stack on piano even though guitar can't manage it?
- Yes — keyboard instruments can voice more of an 11th chord's stack across two hands, which is part of why guitar's reduced version sounds leaner than an arranger's full piano chart might suggest.
- Is the eleventh in B11 ever raised instead of natural?
- In more chromatic jazz harmony, yes — a sharp eleventh creates a different, more Lydian-flavored color, though the natural eleventh used in this standard voicing is by far the more common default.
