You might see the scale written as starting and ending on a Gb and this can give the scale a ‘complete’ sound. The scale can also be repeating at higher or lower octaves and technically goes on forever. 

G Flat Major is a diatonic scale, which means that it is in a key, in this case the key of Gb!

How Is The Gb Major Scale Created?

All Major scales follow a specific pattern of tones and semitones (steps and half steps). The tone pattern is:

Tone, Tone, Semi-tone, Tone, Tone, Tone, Semi-tone

If we take the start at a C and follow the pattern we will get the C Major Scale. To create the G flat Major scale, follow the tone/semitone pattern starting on the note Gb. 

 Whichever note you start on, you will always achieve the major scale starting on this note.

  • 1st – Tonic
  • 2nd – Supertonic
  • 3rd – Mediant
  • 4th – Subdominant
  • 5th – Dominant
  • 6th – Submediant
  • 7th Leading Note

Key Signature For Gb Major

Rather than writing the flat signs on the individual notes, we can make use of the key signature. Because every single B, E, A, D, G and C in the Gb major scale major are flat, we can simply write this at the start of the piece!

Enharmonic Equivalent Scales

Gb Major and F# Major are enharmonic equivalent scales. This means that they share all the same notes, but just written using enharmonic equivalent notes. You can see this below in the image of both scales.

For example, the note A sharp is in F# Major and the note B flat is in Gb Major. Both these notes are enharmonic equivalents, meaning they sound the same. Learn more about the F sharp major scale here.

 If we say that a piece of music is in the key of G flat major, this means a few things:

  • The key signature will have six flats, these being the following notes B flat, E flat, A flat, D flat, G flat and C flat.
  • The tonic (or root note) of the piece will be G flat. This note will sound the most stable in the whole piece.
  • The piece will mostly use notes from this scale, these could be in any octave.
  • The chords used will be those chords that are in Gb major.
