Which scale is known for having a minor scale with a lowered 2nd degree?

The Phrygian scale is distinguished by its unique structure, particularly characterized by the lowered 2nd degree when compared to the natural minor scale. This distinctive interval gives the Phrygian scale a dark and exotic sound often utilized in various musical genres, especially in flamenco and heavy metal music.

By lowering the 2nd degree, the Phrygian scale creates a half step between the root and the second note, which significantly contributes to its unique tonal qualities. This lowered 2nd is what sets the Phrygian apart from other scales, allowing it to evoke a specific emotional response that is sought after in many musical compositions.

In contrast, the Aeolian scale, also known as the natural minor scale, has a natural 2nd degree. Similarly, the Dorian scale has a major 6th but maintains a natural 2nd, leading to a brighter sound in comparison. The Locrian scale includes a diminished 5th, which adds a tension that is characteristically different from the Phrygian's sound. Therefore, the Phrygian scale stands out with its lowered 2nd degree, making it the correct answer.
