What is the interval sequence for the Phrygian scale?

The Phrygian scale is a minor scale that is characterized by its distinct interval pattern, which sets it apart from other modes. The correct interval sequence for the Phrygian scale consists of the following pattern: a half step, followed by whole steps, and concluding with another half step, which aligns with the sequence of intervals that create its unique sound.

This sequence of intervals is structured as follows: a half step from the first to the second degree, then whole steps from the second to the third and from the third to the fourth degrees, followed again by whole steps to the fifth and sixth degrees, and ending with a half step to the seventh degree. This results in a scale that has a dark and exotic quality, typical of the Phrygian mode.

The other sequences do not correspond to the correct interval pattern for the Phrygian scale. Each of those options represents different modes or scales entirely, which do not capture the unique intervals that define the Phrygian sound. Understanding the correct interval structure is crucial for identifying and utilizing the Phrygian scale effectively in musical contexts.
