Bm cavaquinho chord
Bm (B minor) is built from B, D and F#, the degrees 1–b3–5. On cavaquinho, the main shape is 4 4 3 4, the first diagram, marked with the star.
From B major to Bm, a single note moves — and it feels like the season changed. Hit play below and check.

Why Bm sounds this way
The trick is smaller than it sounds. Two of the three notes didn't move: B and F# stayed put. Only the middle one dropped — a half step, the smallest distance in music — and became D. Go back to the audio and catch the arpeggio note by note and stop at the second note. That's the one. Half a step separates a sunny day from a Monday morning.
How to play Bm on cavaquinho
On the cavaquinho, four steel strings tuned D–G–B–D pack the chord into a small, bright space — every finger counts. So the first position below is your way in — it's the main shape — that's why it carries the ⭐. And do the exercise that's worth a whole lesson: B major, then Bm, then major again. Back and forth ten times, slowly. Your ear learns the difference before your brain does.

Where Bm shows up
In real music, Bm works almost always as v in E minor, iv in F# minor, i in B minor. In pop everywhere it tends to be the famous vi — the chord the chorus runs to when it wants to get serious without changing key. You've heard it a thousand times; now you'll start noticing it.

Where Bm usually goes
Treating Bm as the home chord (i) of a minor key, it tends to go toward the pre-dominant (Em) or the dominant (F#7, from harmonic minor), and the dominant pulls back home. It's a tendency, not a law.
Going beyond Bm
When it's time to improvise, B Dorian (B C# D E F# G# A · 1 2 b3 4 5 6 b7: the minor scale with a major sixth — the minor that smirks); B Aeolian (B C# D E F# G A · 1 2 b3 4 5 b6 b7: the natural minor, the major scale's relative sibling); B Phrygian (B C D E F# G A · 1 b2 b3 4 5 b6 b7: the minor with a lowered second — a Spanish seasoning) work in full. The swaps below are the chord's cousins: different color, same job.

Scales to improvise over Bm
To improvise over Bm as home, the B Aeolian scale fits entirely: it contains every note of the chord. The best fit depends on the key, the surrounding chords and the tensions you want. And when the dominant (F#) pulls back, the leading tone Bb is the note that wants to resolve home.

There's one step left in this story. The serious Bm you just learned has a softer, late-afternoon version that lo-fi and bossa nova love: Bm7. Go hear the difference.
