What the Bm chord sounds like

A minor triad differs from a major one only in the third: it has a minor third, which gives it a darker, sadder colour. In a major key, chords ii, iii and vi are minor.

Notes of the Bm chord

1	B	root
3	D	minor third (3 semitones)
5	F♯	perfect fifth (7 semitones)

How do I read the chord diagram?

Strings run from the lowest (left) to the highest (right) – tick “Left-handed” to mirror it. Rows are frets; a number at the side shows the starting fret. Dots are fingers (1 index, 2 middle, 3 ring, 4 little), a long bar is a barre, × means don't play that string and ○ means play it open.

Why do some songbooks write H instead of B?

In German and Central European notation, H is the note B, and B is the note B♭. So a “B” chord in a German or Hungarian songbook is B♭ in English notation, and an “H” chord is B. Always check which notation your chord chart uses.
