The Bm problem
Bm without the barre.
Bm is the second barre chord most players meet, and the A-shape makes it feel different from F. There are two ways to play a smaller Bm now, and one full barre to grow into. They are not all the same chord.
Bm7
The easy substitute — not the same chord
B · D · F♯ · A
Folk, pop and songs where a Bm7 colour fits. It is the easiest Bm-family shape.
Trade-off: It contains A, the minor seventh. Do not use it where the song needs a plain Bm triad.
Four-string Bm
A true Bm triad without a barre
B · F♯ · B · D
A real B minor triad, with no barre. Good while the full shape is still developing.
Trade-off: No high F♯ and no low B; it sounds smaller than the full barre. Mute the low E and high e.
Full Bm
The goal: A-shape barre at the 2nd fret
B · F♯ · B · D · F♯
The standard Bm barre shape. Learn it after the four-string version feels clean.
Trade-off: The index finger covers five strings; the low E is muted. It is a real barre, not a shortcut.
Which one should you use?
Use the four-string Bm (x2443x) when you need a true B minor triad without a barre. It uses four fingers and no barre; the low E and high e stay muted. It is smaller than the full shape, but it is the same chord.
Use Bm7 (x20202) only when the song wants the added A. It is easier, but it is not Bm. If the song needs a plain Bm, Bm7 will sound wrong even if it is clean.
The full x24432 barre is the standard five-string shape. The index finger covers the A–high e strings at the 2nd fret; the low E is muted. It adds the high F♯ and sounds fuller than the four-string version.
The practice ladder
- Play Bm7 cleanly; check that the open D and B strings ring.
- Play the four-string Bm; check each of the four strings separately.
- Use the four-string Bm in a D–A–Bm–G progression.
- In a separate block, work on the full x24432 barre at the 2nd fret.
- Once the barre rings, use it in the same progression and compare the weight.
Why Bm feels different from F
F is an E-shape: the index covers all six strings and the root is on the low E. Bm is an A-shape: the index covers five strings, the low E is muted, and the root is on the A string. The hand angle is different. If your F is improving but Bm is not, practice the A-shape separately.
What not to do
- Do not call Bm7 “Bm” in a song that needs the triad.
- Do not press the low E in the full Bm shape; mute it.
- Do not avoid every song with Bm. Use the four-string version and keep playing.

Frequently asked questions
What is the easiest way to play Bm without a barre?
The four-string Bm at x2443x is a true B minor triad with no barre. Bm7 at x20202 is easier, but it is a different chord; use it only where the minor-seventh colour fits.
Is Bm7 the same as Bm?
No. Bm is B–D–F♯. Bm7 is B–D–F♯–A. Bm7 can substitute in some songs, but it changes the colour and is not correct everywhere.
Why is the four-string Bm called four-string?
It uses the A, D, G and B strings: x2443x. The low E and high e are muted. It is a complete B minor triad (B–F♯–B–D), just smaller than the five-string barre.
Why does Bm sound thin?
The four-string shape has no low B and no high F♯. That is normal; the full x24432 barre adds the high F♯ and a fuller five-string sound.
Can I use the E-shape Bm at the 7th fret?
Yes, 799777 is a full Bm E-shape. It is useful when the song is already high on the neck, but it is still a barre chord, not an easier alternative.
How long does the full Bm barre take?
Weeks to months, like F. Use Bm7 or the four-string Bm in songs while the full barre develops. Do not wait for a perfect barre to play music.
