B flat
Lowered B note
B flat is a musical note one semitone below B, notated as B♭.
It's the same pitch as A sharp, though context determines which name applies.
B flat major and B flat minor are common keys, and many instruments—trumpets, clarinets, saxophones—are pitched in B flat, meaning their written C sounds as B flat.
