What It Is

An 8-note symmetric scale alternating half step, whole step, half step... - also called the dominant diminished scale. Notes: E, F, F##, G#, A#, B, C#, D.

How It Functions

Contains a dominant 7th chord's root, 3rd, and b7th plus the b9, #9, #11, and 13 alterations, making it a standard improvisational choice over an altered dominant chord.

Mood & Character

Tense and angular - the alternating half/whole steps give it a jagged, unresolved color distinct from any 7-note scale.
