The Bm9 ukulele chord contains B, D, F#, A, C#. Its first ukulele voicing is the movable voicing: G string at fret 4 (middle finger); C string at fret 2 (index finger); E string at fret 5 (little finger); A string at fret 4 (ring finger). As a minor 9th chord it has a distinct job in a progression, and this page explains that job alongside the fingerings, the notes and the practice steps that make it stick.
What notes are in the Bm9 chord?
The Bm9 chord is a minor 9th chord, and its notes are fixed: B, D, F#, A, C#. 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 Bm9 at a glance. On the ukulele, start with the first voicing above and listen for the notes B, D, F#, A, C# in Bm9.
| Note | Interval |
|---|---|
| B | Root |
| D | b3 |
| F# | 5 |
| A | b7 |
| C# | 9 |
The root is B, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Bm9 are b3, 5, b7, 9. Learn those intervals rather than memorising the shape alone, because the same interval pattern transposed to another root gives you the same quality of chord anywhere. On the ukulele, the notes appear in the order the fingering dictates, but the set of notes never changes.
Bm9 sounds warm and jazzy, the sound of slow soul, R&B and minor-key jazz. Listen for that character when you play it — if Bm9 does not sound that way, one of the notes is probably wrong, and the table above is the place to check. On the ukulele, start with the first voicing above and listen for the notes B, D, F#, A, C# in Bm9.
Comparing Bm9 with its closest relatives helps to fix it in your ear. In short, minor 9th against minor 7th: Bm9 adds the 9th C# to the minor 7th chord. The extra note widens the sound without changing the function. Hearing the comparison matters more than reading it: play Bm9, then play the chord it is compared with above, and let your ear find the note that changed. On the ukulele, the movable voicing of Bm9 puts those notes under your fingers in the order the fingering lists them.
How to play Bm9 on ukulele
On the ukulele, Bm9 has 1 voicings in the data below, and each one uses the same notes — B, D, F#, A, C# — 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.
For the movable voicing, Bm9 sits in around fret 2: G string at fret 4 (middle finger); C string at fret 2 (index finger); E string at fret 5 (little finger); A string at fret 4 (ring finger). The stretch is the challenge: the fretted notes span from fret 2 to fret 5, so keep your thumb low behind the neck and let your fingers reach rather than squeezing the neck. Strum or pluck it slowly first and check that every note in Bm9 — B, D, F#, A, C# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Bm9 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 Bm9 up the neck to any key without changing the shape. When you change chords, pick the voicing of Bm9 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Bm9 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, the movable voicing of Bm9 puts those notes under your fingers in the order the fingering lists them.
A short practice routine for Bm9 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 Bm9 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.
Crowding the voicing. Five notes need room. Drop the 5th (F#) first and keep the root, minor 3rd, 7th and 9th. On the ukulele, the movable voicing voicing is the place to hear it in Bm9.
Losing the 9th. Without C# this is just a minor 7th chord. Make sure the note carrying the 9th rings clearly. On the ukulele, start with the first voicing above and listen for the notes B, D, F#, A, C# in Bm9.
Pressing too hard on the nylon strings. Ukulele strings need far less pressure than guitar strings, and pressing hard on Bm9 pulls the notes sharp and tires the hand. Use the lightest touch that gives a clean note, and keep your fingers close to the frets. On the ukulele, start with the first voicing above and listen for the notes B, D, F#, A, C# in Bm9.
Playing the major 3rd. The 3rd must stay minor (D). A major 3rd turns this into a dominant 9th, a different chord entirely. On the ukulele, the movable voicing of Bm9 puts those notes under your fingers in the order the fingering lists them.
Where Bm9 is used
Bm9 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 D major, the key of G major, the key of A major. a tonic in minor-key jazz and soul, where the 9th adds depth without tension. 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 Bm9 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the ukulele, start with the first voicing above and listen for the notes B, D, F#, A, C# in Bm9.
Because Bm9 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 Bm9 in a progression in any key and hear how it connects to the chords around it. On the ukulele, the movable voicing voicing is the place to hear it in Bm9.
The same chord on other instruments is covered in Bm9 on guitar, Bm9 on piano, Bm9 on bass, and the scales that fit over it are the B major scale and the B minor pentatonic scale. Learning Bm9 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# — in your memory, because the notes stay the same while everything else changes.
Practising Bm9
A short worked example makes Bm9 concrete. Play the four-chord progression E – B – C#m – A in E major, the key Bm9 most often resolves toward: E – B – C#m – A. Play each chord for one bar at a slow tempo, and listen to how Bm9 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 Bm9 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 Bm9.
For a second exercise, play Bm9 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 Bm9 is built for when it acts as a dominant. Finish by playing Bm9 on its own, slowly, and naming each note out loud as you play it: B, D, F#, A, C#. 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# in Bm9.
