A
B sharp if it is one and a half step up, but if just half then it is A sharp. -BJ
G sharp
A B sharp is actually a C, and it's a half step up from B and a half step down from C sharp. So basically its between B natural and C sharp.
the note is an A This question is not clear; assuming 'half a step' means a semitone then the answer is G# aka Ab.
On the piano, if one plays B-sharp the heard note is C-natural. Conversely if one plays C-flat, the heard note is B-natural. For the same reasons the interval between E and F is also a half step. A musical scale can have only 12 semi-tones (half-steps).
it makes the note a half step higher

A sharp raises a note by half a step, while a flat lowers a note by half a step on the piano. For example, if a note is played as C♯, it is one half step higher than C; if played as C♭, it is one half step lower than C.
In music, a flat is a half step down from a note. It is the opposite of a Sharp which is a half step up. Sharps and Flats on the piano are the black keys.
G sharp
The pattern of intervals that make up the 7 sharp scale is whole step, whole step, half step, whole step, whole step, whole step, half step.
To find sharp key signatures, look at the last sharp in the key signature and go up one half step. This note is the leading tone and indicates the key of the music.

For half step sharps, the most commonly used and the one you are probably referring to that raises a pitch a half tone up, you use a # symbol. If you are writing on manuscript (staff paper), you write the # symbol before the note. If you are writing it on regular notebook paper, you write it after the note name, i.e. C#. For whole step sharps, which raises a pitch a whole tone up, you use a x symbol. The position of the symbol is the same as half step sharps. For quarter step sharps, which are unconventional in western music but used in oriental music, look it up on wikipedia. The position of the symbol is the same as half step sharps also.
