The Phrygian mode is a minor mode. It differs from the natural minor in that it has a flattened second note. This scale is used frequently in Persian music where it is referred to as the Persian major.

This scale produces a mood that is dark, Spainish, mideval, and possibly evil. It is a quentissentially Spainish scale.

It has been used for centuries by the brilliant composers of Spain. It is typical in the beautiful Andalusian Folk music of Spain and was explored extensively by the brilliant Spainish Composer Francisco Tarrega. (1852-1909)

Tarrega is credited with establishing the foundation for guitar technique in the 20th century.
He is also recognized for spurring renewed interest in the guitar as a serious recital instrument, transcending it’s place as a “parlor instrument.”

Tarrega was a favortie of the infamous guiratrist Andres Segovia, who played Tarrega’s music extensively and helped to complete the guitar’s conversion from “parlor instrument” to “concert instrument.”

A melody from Tarrega’s “Gran Vals” was adopted as the cingular ring tone and is now considered to be one of the most heard melodies of all time.
