The Bsus4 mandolin chord contains B, E, F#. Its first mandolin voicing is the movable voicing: G string at fret 4 (middle finger); D string at fret 4 (middle finger); A string at fret 2 (index finger); E string open. As a suspended 4th 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 Bsus4 chord?
The Bsus4 chord is a suspended 4th chord, and its notes are fixed: B, E, F#. 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 Bsus4 at a glance. On the mandolin, start with the first voicing above and listen for the notes B, E, F# in Bsus4.
| Note | Interval |
|---|---|
| B | Root |
| E | 4 |
| F# | 5 |
The root is B, the note the chord is named after and the note your ear hears as home. Above it, the intervals in Bsus4 are 4, 5. 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 mandolin, the notes appear in the order the fingering dictates, but the set of notes never changes.
Bsus4 sounds open but restless, the classic suspended sound that every listener recognises as unfinished business. Listen for that character when you play it — if Bsus4 does not sound that way, one of the notes is probably wrong, and the table above is the place to check. On the mandolin, start with the first voicing above and listen for the notes B, E, F# in Bsus4.
Comparing Bsus4 with its closest relatives helps to fix it in your ear. In short, sus4 against sus2: Bsus4 uses the 4th E where the sus2 uses the 2nd C#. The sus4 is tenser and its resolution to the 3rd is more dramatic. 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 mandolin, start with the first voicing above and listen for the notes B, E, F# in Bsus4.
How to play Bsus4 on mandolin
On the mandolin, Bsus4 has 3 voicings in the data below, and each one uses the same notes — B, E, F# — in a different place on the neck. The first voicing below is the one to learn first, and the alternatives cover the rest of 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, Bsus4 sits in around fret 2: G string at fret 4 (middle finger); D string at fret 4 (middle finger); A string at fret 2 (index finger); 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 Bsus4 — B, E, F# — sounds, with no buzz and no accidental open string.
For the barre chord, Bsus4 sits in around fret 2: G string at fret 4 (middle finger); D string at fret 2 (index finger); A string at fret 2 (index finger); E string at fret 2 (index finger). It barres across strings 2 to 4 at fret 2 with the index finger. The barre is the hard part: the index finger must press every string from 2 to 4 evenly at fret 2, 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 Bsus4 — B, E, F# — sounds, with no buzz and no accidental open string.
Another way to play Bsus4 is the barre chord, in around fret 4: G string at fret 4 (index finger); D string at fret 4 (index finger); A string at fret 7 (middle finger); E string open. 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 Bsus4 — B, E, F# — sounds, with no buzz and no accidental open string.
Choosing between the voicings of Bsus4 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 Bsus4 up the neck to any key without changing the shape. When you change chords, pick the voicing of Bsus4 that sits closest to the chord before it — shorter moves between shapes mean faster, cleaner changes. Practise the change into Bsus4 from the chord that comes before it in your song, not the chord on its own, because the move is the skill. On the mandolin, the movable voicing voicing is the place to hear it in Bsus4.
A short practice routine for Bsus4 on the mandolin: 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 Bsus4 sound wrong on the mandolin, and each one has a concrete fix. Work through them one at a time rather than trying to fix everything at once.
Never resolving the 4th. The 4th E wants to fall to D#. If you sit on the sus4 forever the chord sounds stuck. Practise the sus4-to-major move until the resolution feels natural. On the mandolin, start with the first voicing above and listen for the notes B, E, F# in Bsus4.
Resolving to the wrong 3rd. The sus4 resolves to the major 3rd D#, not the minor 3rd. Resolve to D and you have changed key, not resolved. On the mandolin, the movable voicing of Bsus4 puts those notes under your fingers in the order the fingering lists them.
Playing the 3rd as well. If D# sounds together with E the chord clashes badly. The 3rd must be absent while the 4th is present. On the mandolin, the movable voicing of Bsus4 puts those notes under your fingers in the order the fingering lists them.
Hitting it too hard. A sus4 played at full volume can sound harsh. Play it a touch softer than the chord it resolves to. On the mandolin, the movable voicing voicing is the place to hear it in Bsus4.
Where Bsus4 is used
Bsus4 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 way to delay a chord: play the sus4, hold it, then let it fall to the triad. 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 Bsus4 does its work: not as a home chord, but as a chord that creates movement and then resolves. On the mandolin, start with the first voicing above and listen for the notes B, E, F# in Bsus4.
Because Bsus4 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 Bsus4 in a progression in any key and hear how it connects to the chords around it. On the mandolin, the movable voicing of Bsus4 puts those notes under your fingers in the order the fingering lists them.
The same chord on other instruments is covered in Bsus4 on guitar, Bsus4 on piano, Bsus4 on ukulele, and the scales that fit over it are the B major scale and the B minor pentatonic scale. Learning Bsus4 on the mandolin and then checking it on another instrument is one of the best ways to fix the notes — B, E, F# — in your memory, because the notes stay the same while everything else changes.
Practising Bsus4
A short worked example makes Bsus4 concrete. Play the four-chord progression E – B – C#m – A in E major, the key Bsus4 most often resolves toward: E – B – C#m – A. Play each chord for one bar at a slow tempo, and listen to how Bsus4 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 Bsus4 itself, and notice how its character changes when it opens the progression instead of sitting inside it. On the mandolin, the movable voicing voicing is the place to hear it in Bsus4.
For a second exercise, play Bsus4 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 Bsus4 is built for when it acts as a dominant. Finish by playing Bsus4 on its own, slowly, and naming each note out loud as you play it: B, E, F#. 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 mandolin, the movable voicing of Bsus4 puts those notes under your fingers in the order the fingering lists them.
Frequently asked questions
What is the easiest voicing of Bsus4 on the mandolin?
The movable voicing is the easiest voicing listed for Bsus4 on the mandolin: frets 4–4–2–0, fingers 2–2–1–0. Learn that shape first, get every note ringing cleanly, and only then move on to the alternative voicings further up the neck.
What does sus4 mean in Bsus4?
Sus4 means the 3rd of the chord is suspended — replaced by the 4th, E. Bsus4 contains B, E, F#, and the 4th is the note that makes it sound tense and unresolved. On the mandolin, the voicings above put that note under your fingers.
How do you resolve Bsus4?
Let the 4th E fall by a semitone to the major 3rd D#. That one-step move, sus4 to major, is the classic resolution and the sound every listener expects. On the mandolin, the voicings above put that note under your fingers.
Is Bsus4 major or minor?
Neither, while it is suspended: it has no 3rd. It usually resolves to the major triad, which is why it is most often heard as a delayed major chord. On the mandolin, the voicings above put that note under your fingers.
How do you play Bsus4 on the mandolin?
The first voicing is the movable voicing: frets 4–4–2–0, fingers 2–2–1–0, on the mandolin. That voicing uses the notes B, E, F#, and it is the one to learn first. The page above lists more voicings for Bsus4, so you can choose the shape nearest the chords around it.
