Which description fits the Melodic Minor scale?

The Melodic Minor scale is characterized by its unique ascending and descending patterns. When ascending, the scale features a sharpened sixth and seventh degree compared to the Natural Minor scale, which gives it a distinct sound and allows for smoother melodic lines, often leading to resolution in the following chords. When descending, the scale reverts to the Natural Minor form, resulting in natural sixth and seventh degrees.

This dual nature of the Melodic Minor scale is essential for its usage in various musical contexts, particularly in jazz and classical music, where it can create tension and resolve in a pleasing way. The ascending form is often preferred in melody and improvisation, while the descending form allows for a more grounded resolution.

In contrast, the other descriptions do not accurately represent the unique qualities of the Melodic Minor scale. The natural pitch both ascending and descending would refer to the Natural Minor scale, while stating that anyone can play the scale does not capture the specific technical aspects of its structure. Lastly, claiming that all notes belong to the major scale overlooks the fact that the Melodic Minor scale has its own distinct degrees and structure that deviate from the major scale.
