B11 on the ukulele is a dominant 11th chord made from B, D#, F#, A, C#, E. Its first ukulele voicing is the movable voicing: G string at fret 4 (middle finger); C string at fret 3 (index finger); E string open; A string open. Below you will find its notes and intervals, every usable voicing on the ukulele, the common mistakes players make with it and the keys and progressions where it belongs.
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 ukulele, the movable voicing 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 ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
B11 sounds complex but smooth, a dominant chord with an extra note that softens its edge. The colour is strongest when all the notes ring clearly. A muted chord tone, especially the 3rd or the 7th where the chord has one, flattens the character of B11 noticeably. On the ukulele, the movable voicing of B11 puts those notes under your fingers in the order the fingering lists them.
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 ukulele, the movable voicing of B11 puts those notes under your fingers in the order the fingering lists them.
How to play B11 on ukulele
On the ukulele, 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. There are 3 voicings listed for B11 on the ukulele; learn the first, then add the others as you need them. 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.
For the movable voicing, B11 sits in around fret 3: G string at fret 4 (middle finger); C string at fret 3 (index finger); E string open; A string open. This voicing is comfortable because the fretted notes sit close together, from fret 3 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.
The barre chord puts B11 in around fret 4: G string at fret 4 (index finger); C string at fret 4 (index finger); E string at fret 5 (middle finger); A string at fret 6 (ring finger). It barres across strings 1 to 2 at fret 4 with the index finger. The barre is the hard part: the index finger must press every string from 1 to 2 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.
For the open position, B11 sits in around fret 1: G string at fret 2 (index finger); C string at fret 3 (ring finger); E string open; A string at fret 2 (middle finger). This voicing is comfortable because the fretted notes sit close together, from fret 2 to fret 3, 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 ukulele, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
A short practice routine for B11 on the ukulele: 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.

Common mistakes
These are the mistakes that most often make B11 sound wrong on the ukulele, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Playing the 3rd and 11th together. D# and E clash badly in the same octave. In an 11th chord the 3rd is usually omitted or placed far from the 11th. On the ukulele, the movable voicing of B11 puts those notes under your fingers in the order the fingering lists them.
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 ukulele, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
Playing the 11th too low. E low down sounds muddy against the root. Keep it high in the voicing. On the ukulele, the movable voicing of B11 puts those notes under your fingers in the order the fingering lists them.
Using it as a tonic. B11 is a dominant chord. It wants to resolve to the tonic. On the ukulele, the movable voicing 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 dominant colour in jazz, where the 11th replaces the 3rd in the voicing to avoid a clash. 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 ukulele, the movable voicing voicing is the place to hear it in B11.
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 ukulele, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
The same chord on other instruments is covered in B11 on guitar, B11 on piano, 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 ukulele 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 ukulele, the movable voicing voicing is the place to hear it 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 ukulele, start with the first voicing above and listen for the notes B, D#, F#, A, C#, E in B11.
