The Gb Major Scale Formula

This formula is the formula of every major scale, not just the Gb major scale! This is a certain pattern that colors what we hear in a specific tone and when copying this pattern to another root we get another major scale.

the C major scale formula

Notice that the semitones of the Gb Major Scale are located between Bb-Cb and F-Gb.

The Gb Major scale roman numerals

The roman numerals system is a technique that doesn't use the actual notes of each scale, instead, it uses a degree that symbolizes every note of the scale

This formula is a lot easier to operate in your head while playing, instead of thinking about notes, you're thinking in "templates". Because this is a note-less system, it fits as it is to every major scale!
