Step pattern
H – W – W – H – W – W – W
From the root to the octave the scale moves in this pattern: H – W – W – H – W – W – W.
W = whole step (2 semitones), H = half step (1 semitone), W+H = 3 semitones
Sound and character
The most dissonant mode — a diminished 5th built right into the scale. Unstable by design. Rarely used melodically, but beloved in heavy metal.
Sound: Dissonant & extreme
