Discover the G Flat Major Scale

The G flat major scale has six flats giving us B, E, A, D, G and C flatted in this scale. The scales are a little easier to remember if you’re familiar with the circle of 4ths.

This scale is made from tetra-chords in the C flat and D flat major scales.

The C flat scale is the same as the B scale. The C flat scale is really only used for teaching. It’s the C scale with every note flatted which would be confusing. The B scale only has 5 sharps making it a little easier to read.

These scales are related and you will see the same chords in the G flat, C flat and D flat major scales.

These scale names are also the names of the major chords in the G flat scale.

G Flat Tetra-Chords

A tetra-chord is a group of four notes that make up one half of a major scale. Major scales have two tetra-chords in them from two other related major scales.

The first G flat tetra-chord comes from the second C flat scale tetra-chord and the second tetra-chord comes from the first tetra-chord in the D flat major scale.

The G Flat Major Scale Numbering

Major scales have numbers that go with the notes. This lets you refer to any scale note or chord in any key with one statement like …iim7 to V7 progression would be… Dm7 to G7 in the key of C or

Gm7 to C7 in the key of F.

When referring to chords the numbers are written in Roman numerals, upper case for major chords(I, IV V7) and lower case for minor and diminished chords(iim7, iiim7, vim7).

The G Flat Major Key signature

This is how the key signature will look if you are in the key of G♭. The flat symbol circles the B, D and G lines and the E, A, and C spaces in the staff.

This doesn’t mean the music won’t have other flats or sharps. They will be marked in the music itself on the staff but the B, E, A, D, G and C won’t be so you have to remember them. The F is the only note that’s not flat in this key.

The flat keys spell words as you cycle through the 4ths starting with B then BE then BEA then BEAD then BEADG then BEADGC and thats it, no more. This might help you remember the flats.

If you know the circle of fourths it’s fairly easy to remember the flats. The guitar is tuned in 4th’s except for the 3rd to 2nd strings which is a major 3rd interval.
