The B11 guitar chord is built from the notes B, D#, F#, A, C#, E. Its first guitar voicing is the open position: low E string open; A string open; D string at fret 1 (index finger); G string at fret 2 (middle finger); B string open; high e string open. It is a dominant 11th chord, and this page gives you its exact notes, the fingerings that work on the guitar, the mistakes to avoid and the progressions it appears in.
What notes are in the B11 chord?
The B11 chord is a dominant 11th chord, and its notes are fixed: B, D#, F#, A, C#, E. Every voicing on every instrument uses these same notes, in some order and in some octave — change one of them and you are playing a different chord. The table below lists each note with its interval from the root B, so you can see the structure of B11 at a glance. On the guitar, the open position of B11 puts those notes under your fingers in the order the fingering lists them.
| Note | Interval |
|---|---|
| B | Root |
| D# | 3 |
| F# | 5 |
| A | b7 |
| C# | 9 |
| E | 11 |
The root is B, the note the chord is named after and the note your ear hears as home. Above it, the intervals in B11 are 3, 5, b7, 9, 11. That combination is what makes B11 sound the way it does: the intervals decide the colour, and the root decides the pitch. On the guitar, the notes appear in the order the fingering dictates, but the set of notes never changes.
B11 sounds open and modern, the sound of jazz and fusion dominants. Listen for that character when you play it — if B11 does not sound that way, one of the notes is probably wrong, and the table above is the place to check. On the guitar, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
Comparing B11 with its closest relatives helps to fix it in your ear. In short, 11th against 9th: B11 adds the 11th E on top of the 9th C#. In practice the 3rd is often left out of the voicing, because the 11th clashes with it. Practise the two chords back to back and listen to the one note that changes — that single note is the difference between the two chords. On the guitar, the open position of B11 puts those notes under your fingers in the order the fingering lists them.
How to play B11 on guitar
On the guitar, B11 has 3 voicings in the data below, and each one uses the same notes — B, D#, F#, A, C#, E — in a different place on the neck. Start with the first voicing and get it clean before you try the movable shapes further up the neck. Finger numbers below use 1 for the index finger, 2 for the middle finger, 3 for the ring finger and 4 for the little finger, and x means the string is not played.
Another way to play B11 is the open position, in open position: low E string open; A string open; D string at fret 1 (index finger); G string at fret 2 (middle finger); B string open; high e string open. This voicing is comfortable because the fretted notes sit close together, from fret 1 to fret 2, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in B11 — B, D#, F#, A, C#, E — sounds, with no buzz and no accidental open string.
For the barre chord, B11 sits in around fret 4: low E string at fret 7 (middle finger); A string open; D string at fret 4 (index finger); G string at fret 4 (index finger); B string at fret 4 (index finger); high e string open. It barres across strings 3 to 5 at fret 4 with the index finger. The barre is the hard part: the index finger must press every string from 3 to 5 evenly at fret 4, so roll it slightly onto its bony side and keep it close to the fret wire. If the barre buzzes, move it a fraction closer to the fret and press from the arm, not the thumb alone. Strum or pluck it slowly first and check that every note in B11 — B, D#, F#, A, C#, E — sounds, with no buzz and no accidental open string.
Another way to play B11 is the movable voicing, in around fret 2: low E string open; A string open; D string at fret 2 (index finger); G string at fret 4 (middle finger); B string at fret 4 (middle finger); high e string open. This voicing is comfortable because the fretted notes sit close together, from fret 2 to fret 4, so your hand stays relaxed and every note can ring. Strum or pluck it slowly first and check that every note in B11 — B, D#, F#, A, C#, E — sounds, with no buzz and no accidental open string.
Choosing between the voicings of B11 is a musical decision, not a right-or-wrong one. The open or low-position voicing rings the most and suits strumming, while a barre or movable voicing lets you slide B11 up the neck to any key without changing the shape. When you change chords, pick the voicing of B11 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into B11 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the guitar, the open position of B11 puts those notes under your fingers in the order the fingering lists them.
A short practice routine for B11 on the guitar: play the first voicing four times slowly, checking each note, then change to it from the chord a fourth above B and back, four times, at a slow tempo. Then play the second voicing the same way. If a note buzzes, stop and fix the finger placement rather than playing through the buzz — clean notes at a slow tempo become clean notes at full tempo, while buzzes practised fast become habits. Use the Guitar Chord Finder to see the diagram for B11 while you practise, and the Chord Finder to compare it with the same chord on other instruments.
Common mistakes
These are the mistakes that most often make B11 sound wrong on the guitar, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Crowding six notes. Six notes are too many for most voicings. Drop the 5th and often the 3rd too, keeping root, 7th, 9th and 11th. On the guitar, the open position of B11 puts those notes under your fingers in the order the fingering lists them.
Playing the 11th too low. E low down sounds muddy against the root. Keep it high in the voicing. On the guitar, the open position voicing is the place to hear it in B11.
Using it as a tonic. B11 is a dominant chord. It wants to resolve to the tonic. On the guitar, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
Barre collapsing on the high strings. In a barre voicing of B11, the high strings are the ones that buzz first, because the index finger presses hardest near the thumb. If the top notes of B11 sound dead, roll the barring finger slightly toward the fret and press from the arm, not from squeezing the neck. On the guitar, the open position voicing is the place to hear it in B11.
Where B11 is used
B11 is not a diatonic triad in any major or minor key, because it is an extended or altered chord, but its base triad belongs to the key of E major, the key of F# major, the key of B major. a colour dominant for slow jazz and fusion, where its width has room to show. As a dominant-type chord it also points toward E major, the key a perfect fourth above B, which is the tonic it most often resolves to. That is where B11 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the guitar, the open position of B11 puts those notes under your fingers in the order the fingering lists them.
Because B11 is an extended or altered chord, it appears in progressions as a colour or a dominant rather than as a diatonic staple. Try it in place of the plain B triad in a progression you already know, and listen to how the extra notes change the feel — that substitution is the usual way extended chords enter real music. The Chord Progression Builder lets you try B11 in a progression in any key and hear how it connects to the chords around it. On the guitar, the open position of B11 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in B11 on piano, B11 on ukulele, B11 on bass, and the scales that fit over it are the B major scale and the B minor pentatonic scale. Learning B11 on the guitar and then checking it on another instrument is one of the best ways to fix the notes — B, D#, F#, A, C#, E — in your memory, because the notes stay the same while everything else changes.
Practising B11
A short worked example makes B11 concrete. Play the four-chord progression E – B – C#m – A in E major, the key B11 most often resolves toward: E – B – C#m – A. Play each chord for one bar at a slow tempo, and listen to how B11 sounds in that sequence — whether it feels like home, like a lift, or like a chord on its way somewhere else. Then play the same four chords in a different order, starting on B11 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the guitar, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
For a second exercise, play B11 and then the chord a fourth above B, back and forth, four times each. That move — a chord and the chord a fourth above it — is the most common resolution in Western music, and it is the move B11 is built for when it acts as a dominant. Finish by playing B11 on its own, slowly, and naming each note out loud as you play it: B, D#, F#, A, C#, E. Naming the notes while you play them is what turns a shape into knowledge you can use in any key. Test yourself with the Practice Chord Quiz and keep time with the Metronome as the tempo rises. On the guitar, the open position voicing is the place to hear it in B11.
Frequently asked questions
Where is B11 used?
B11 is a dominant colour in jazz and fusion, used as a V11 that resolves to the tonic. It suits slow tempos and open voicings where its width can be heard. On the guitar, the first voicing above shows where that note sits.
How do you play B11 on the guitar?
The first voicing is the open position: frets 0–0–1–2–0–0, fingers 0–0–1–2–0–0, on the guitar. That voicing uses the notes B, D#, F#, A, C#, E, and it is the one to learn first. The page above lists more voicings for B11, so you can choose the shape nearest the chords around it.
Is B11 hard to play on the guitar?
It depends on the voicing. The first voicing of B11 on the guitar is the easiest starting point, and the movable voicings further up the neck are harder because they need a barre or a wider stretch. Practise the first voicing cleanly at a slow tempo before you try the others, and the harder shapes will come more easily.
What is the easiest voicing of B11 on the guitar?
The open position is the easiest voicing listed for B11 on the guitar: frets 0–0–1–2–0–0, fingers 0–0–1–2–0–0. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
What notes are in B11?
B11 contains B, D#, F#, A, C#, E: root, major 3rd, perfect 5th, flattened 7th, 9th and 11th. In practice the 3rd is often omitted from the voicing, because it clashes with the 11th. On the guitar, the first voicing above shows where that note sits.
