The Phrygian mode features a dark and exotic tonality due to its minor scale foundation with a flattened second degree. Its distinctive flattened second creates a sense of tension and mystery, evoking feelings of intensity and drama, often found in flamenco, metal, and other music styles seeking a haunting and passionate atmosphere. In terms of intervals, it's simply the Natural Minor with a flattened 2nd: 1, ♭2, ♭3, 4, 5, ♭6, ♭7.
