Phrygian Mode

The Phrygian mode on the guitar is a dark, exotic scale with a distinct Spanish or Middle Eastern sound that is heavily used in heavy metal, flamenco, and progressive rock. It is the third mode of the major scale, built by flattening the second, third, sixth, and seventh notes of a standard major scale (1, b2, b3, 4, 5, b6, b7). Guitarists prize this mode for its immediately recognizable half-step interval right at the start of the scale (from the root to the flat second). This tight, tense interval creates a sinister, brooding atmosphere that is perfect for aggressive metal riffs and suspenseful acoustic melodies.
