A diatonic semitone is usually represented by the adjacent letter names. The next higher letter pitch to C is D. The answer is D (natural).
A whole step above C sharp (C#) is D sharp (D#). In music, a whole step consists of two half steps, and moving from C# to D# involves skipping the note D, which is a half step above C#.
The note above F can be labelled as F sharp or G flat.
A sharp.
One half step higher than G sharp is A. In musical terms, a half step is the smallest interval, and moving up from G sharp to A involves raising the pitch by one semitone.
C#/Db is a half step above C.
B sharp if it is one and a half step up, but if just half then it is A sharp. -BJ
A whole step above C sharp (C#) is D sharp (D#). In music, a whole step consists of two half steps, and moving from C# to D# involves skipping the note D, which is a half step above C#.
The symbol to lower a note a half step is called a flat.
B (B natural).
A sharp, also known as B flat.
It is usually written just to the right of the note. A sharp means to raise one half step and flat means to lower one half step.
Sharp (usually a half step above the natural note)
It is a note a half step above or below the original note (a sharp or flat).
It means the tone is 1/2 step above the note given. A full step would be to go from A to B, therefore a half step would be A sharp.
The note above F can be labelled as F sharp or G flat.
One half step above G is G-sharp (or A-flat). In musical terms, this means that if you move up from G to the next closest note, you reach G-sharp/A-flat.
A sharp.
