How to play B♭ minor

Guitar
×332EADGBe

Leave the low E string out. Lay your first finger flat across fret 1 and let the other fingers take the notes above it. Nothing is higher than fret 3, so it sits in first position.

Ukulele
3111GCEA

All four strings are played. Nothing is higher than fret 3, so it sits in first position.

Piano
FD♭B♭

Play B♭, D♭ and F together. That is one white key and two black.

Numbers in the grids are frets. Where a number is printed beside a grid, that is the fret the top row stands for; otherwise the thick bar at the top is the nut. A circle above a string means play it open, a cross means leave it out.

B♭ minor on the stave

The same three notes written on a treble stave, spelled the way a minor triad is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads B♭, D♭ and F, and not the same sounds written some other way.
