Other Scales – The Diminished Scale

The diminished scale contains a flat 3rd note (minor 3rd), a flat 5th note, and a double flat 7th note (compared to the major scale), so the step pattern is:

tonesemitone(b3rd)tonesemitone(b5th)tonesemitone(bb7th)1+1/2tone
A^B^C^D^Eb^F^Gb^A
Frets:2121213
Step Pattern for a Diminished Scale

Listen:

FINGERING FOR ROOT NOTE ON 5TH STRING:

This pattern can be used when the root note of the natural minor scale falls anywhere on the 5th string.

FINGERING FOR ROOT NOTE ON 6TH STRING:

This pattern can be used when the root note of the natural minor scale falls anywhere on the 6th string.

This is a useful scale to know when changing keys in lead work. The diminished scale has a unique property in that the root, b3rd, b5th and bb7th will share the same notes across the four keys that these notes contain, for example:

Diminished scalerootb3rdb5thbb7th
Key of AACEbGb
Key of CCEbGbA
Key of EbEbGbAC
Key of GbGbACEb
Notes of the Diminished Scale contain the same notes across four keys

Therefore only 3 diminished scales are needed to cover all twelve keys.
