phrygian
A minor mode with a flat second: dark and tense, the Spanish and metal sound.
A minor mode with a flat second, a semitone sitting right above the home note. That low, leaning second gives Phrygian its dark, tense, unmistakably Spanish and heavy-metal color. Its characteristic note is the flat 2nd.
