a sharp in a scale
A) lowers the note by 1/2 step
B) raises the note by one whole step
C) raises the know by 1/2 step
D) lowers the no by one whole step
The answer to your question is:
A sharp in a scale raises the note by 1/2 step.
To understand this, let's first clarify what a sharp symbol means in music theory. A sharp (♯) is a musical symbol that indicates raising a note by one half step. A half step is the smallest interval or distance between two notes in Western music.
To demonstrate this, let's take the C major scale as an example. The C major scale consists of the notes C, D, E, F, G, A, and B. If we want to raise the note C by a half step, we would use a sharp symbol, resulting in C♯. So, the scale with the sharp would be C♯, D, E, F, G, A, and B.
Therefore, the correct answer is option C) raises the note by 1/2 step.
