A, sharp in a scale

Answer 1

In music theory, the sharp symbol (#) indicates a raised pitch by one half step. When applied to a scale, it means that a specific note within the scale is raised by one half step.

For example, if we consider the C major scale, which consists of the notes C, D, E, F, G, A, and B, the A sharp (A#) would be the raised version of A. So, the C major scale with an A sharp (A#) would be:

C, D, E, F, G, A#, B

Alternatively, you could also notate it as the B flat (B♭) since A# and B♭ represent the same pitch. So, the C major scale with a B flat (B♭) would be:

C, D, E, F, G, B♭
