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 6 flats.
