G major scale

G – A – B – C – D – E – F♯

The G major scale runs G, A, B, C, D, E, F♯ and then back to G. It follows the major step pattern — tone, tone, semitone, tone, tone, tone, semitone — which is what makes it major rather than any other kind of scale.

It uses each letter name once, which is why it is written with 1 sharp.
