The Phrygian scale is a minor mode that originates from the ancient Greek musical tradition, but it has found a special place in modern music, particularly in the realms of flamenco, Latin, and rock genres. It is recognized as the third mode of the major scale, starting on the third degree of the major scale. Therefore, if you play the Phrygian scale of C major, you would begin on E (E Phrygian). The scale's unique sound is characterized by a half step between the first and second notes, giving it a darker, more exotic feel compared to other minor scales. Featuring the intervals: 1 (root), b2 (minor second), b3 (minor third), 4 (perfect fourth), 5 (perfect fifth), b6 (minor sixth), and b7 (minor seventh), the Phrygian mode has a flattened second which contributes heavily to its distinct tonal qualities. Guitarists often utilize the Phrygian scale to evoke mood and atmosphere in their music, exploring its haunting and mystical qualities. It's common to find the scale's employment in soloing, especially when aiming for a sound that resides somewhere between mysterious and intense. Techniques such as using slides and hammer-ons can effectively enhance the scale's naturally brooding and lyrical aesthetics. Players can develop a deeper understanding and creativity with the Phrygian mode by experimenting over backing tracks with matching tonal centers.
