A-sharp
Enharmonic with B-flat
A-sharp is a musical note one semitone above A, enharmonically equivalent to B-flat—they sound identical but are written differently depending on the key.
A-sharp appears less frequently than its equivalent because most keys favor B-flat notation: The passage modulates through A-sharp minor.
