Music: What note is a whole step higher than a B-Sharp note?

B# is a white key on the piano. Another name for B# is C, which has the same note pitch / sound, which means that the two note names are enharmonic to each other. It is called sharp because it is 1 half-tone(s) / semitone(s) up from the white note after which is is named - note B. The next note up from B# is C# / Db.

🤷‍♂️Something I could never hope to hit.
