In the Phrygian mode, where do the half steps occur?

In the Phrygian mode, the interval structure is defined by its unique sequence of whole and half steps, which distinguishes it from other modes. Specifically, the Phrygian mode is derived from the major scale, starting on the third degree. The half steps in this mode occur between the first and second degrees, as well as between the fifth and sixth degrees.

This means that the half step between the first and second notes creates a distinctive sound characteristic of the Phrygian mode, contributing to its exotic quality. Similarly, the half step between the fifth and sixth notes leads to a tension that is often exploited in composition and improvisation, enhancing the overall feel and mood of the music created in this mode.

While the other answer choices address different pairs of degrees, they do not reflect the accurate location of half steps within the Phrygian mode. It is essential to recognize that each mode's structure impacts the emotional and auditory qualities of the music, making understanding these intervals crucial for musicians working within modal contexts.
