Is b flat note in higher in b note?

Answer 1

Any note which is "flat" is always one half step lower that the specific white note you're talking about, B-flat is one half step lower than B, so that is the black key just to the left of B. Thus A-flat is the black key just to the left of A, G-flat is the black key just to the left of G, E-flat is the black key just to the left of E and D-flat is the black key just to the left of D.

For C-flat and F-flat, there are no black keys between B and C & E and F so therefore C-flat would have to be B and F-flat would have to be E.

Any note which is "sharp" is always one half step to the right of the specific white note your labelling. Thus F-sharp is the black key directly to the right of F, G-sharp is the black key to the right of G, A-sharp is the black key to the very right of A. C-sharp is the black key to the right of C and D-sharp is the black key to the very right of D.

For E-sharp and B-sharp, since there is no black key between the notes I mentioned above, E-sharp would sound the same as F and B-sharp would be the same as C.

Most of the time when we're talking about "sharps" and "flats", we're referring to a black key.

Answer 2

In the context of the question, this cannot be answered because there are many octaves in music.

Answer 3

When you flat a Bb you go down one half step, so you would be playing a A.
