What is the number of sharps in the G Major scale?

The G Major scale consists of one sharp, which is F#. This can be understood by looking at the pattern that major scales follow. A major scale is constructed using a specific sequence of whole and half steps. For the G Major scale, the notes are G, A, B, C, D, E, and F#, leading you back to G.

The presence of F# is essential because it maintains the required whole and half step intervals for a major scale.

To summarize, the G Major scale is unique in containing just one sharp, distinguishing it from other major scales, such as D Major which has two sharps, or E Major which has four sharps.
