How many sharps are in the A Major scale?

The A Major scale contains three sharps. The sharps in this scale are F#, C#, and G#. Understanding this is essential when constructing the A Major scale or when playing music in this key.

In a Major scale, the pattern of whole and half steps is crucial, consisting of: whole, whole, half, whole, whole, whole, half. This pattern helps to determine the specific notes in the scale. Starting on A and applying this pattern results in the sequence A, B, C#, D, E, F#, G#, and finally back to A. Thus, recognizing the specific sharps is important not just for identification, but for proper playing and composition within this key.

The other choices do not represent the correct number of sharps in the A Major scale, as they either underrepresent or miscount the sharps necessary for achieving the characteristic sound of the scale.
