c flat. the semitone above b flat is b, with is equal to c flat. So the diatonic semitone is c flat because it has to be a different note name.

Sharps are the note one semitone higher than a given natural note, for example, D-sharp is one semitone higherthan D.Flats are the note one semitone lower than a given natural note, so D-flat is one semitone lower than D.Natural signs get rid of a previous sharp or flat in the same bar, or raises or lowers a sharp or flat already included in the key signature - e.g. the F-sharp in G major.Sharps and flats can be modified further too - resulting in a double sharp or double flat - which means that any double sharp or double flat will be a whole tone higher or lower than a given natural note, for example, D double-sharp would be the same key as E and D double-flat would be the same as C. Again a natural sign would get rid of the double flat or sharp.Sometimes natural keys have to be named as either sharp or flat, e.g. in C-sharp minor the seventh degree is B, but we have to raise B to B-sharp to create a C-sharp harmonic minor scale, which uses a raised seventh. Now we could call the B-sharp 'C' but that would not be correct as we need to use all letter names in a diatonic scale, and technically the C is functioning as a raised B in the key or C-sharp minor.
Raises it by a semitone
B
The note B sharp on the piano is the same key as C natural. It is written as B in notation. B sharp is higher in pitch than B natural but is played on the same key as C natural. This is because in music theory, B sharp is used to indicate a note that is one half step higher than B natural.
B flat major is a scale, which is a series of notes played in succesion, going up and down. The musical note B flat is just one frequency which is a semitone above A. Concert A (the most used middle A) is at 440Hz.
The five black notes in the keyboard can be written as C#, D#, F#, G# and A#. Theoretically, any note has a sharp, a semitone higher pitch. In fact B# and E# are white notes, C and F respectively.
C sharp
Yes, the concept of "B" exists in music theory. It is a musical note that is one half step higher than B natural.
