which note.is.sharp.in g major scale
The notes of the G-sharp major scale are: G#, A#, B#, C#, D#, E#, Fx, G#. The x you see is called a double sharp. (Double sharps raise a note higher by 1 whole step. Fx is actually G.) However, because of the simpler enharmonic equivalent of Ab major, which has 4 flats, Ab major is used a lot more than G# major ever is.
