What is bm on piano?

BM, also known as B minor, is a commonly used minor key in music. It is based on the seventh note of the B Major scale and has a melancholic, emotional feel to it.

Playing BM on the piano involves using the black key between A and B, known as B flat or A sharp, to lower the second and sixth notes of the B Major scale and create the minor scale.

Bm chords on the piano typically involve playing the notes B, D, and F# together. This creates a minor triad, which is often used in sad or emotional music.

Some popular songs that use the Bm chord include "Hotel California" by the Eagles, "Yesterday" by the Beatles, and "Every Breath You Take" by the Police.
