You might see the scale written as starting and ending on a Db 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.

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

How is the Db 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 D flat Major scale, follow the tone/semitone pattern starting on the note Db. 

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

  • 1st – Tonic
  • 2nd – Supertonic
  • 3rd – Mediant

  • 6th – Submediant

Key Signature for Db Major

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

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

  • The key signature will have five flats, these being the following notes B flat, E flat, A flat, D flat and G flat.
  • The tonic (or root note) of the piece will be D 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 Db major.
