What is one characteristic of a minor scale?

A minor scale is characterized by its "sad" or "dark" sound, which is due to the specific arrangement of whole and half steps within the scale. In a natural minor scale, the intervals create a mood that is generally perceived as more somber compared to a major scale. This emotional quality is a defining aspect of minor scales and is widely used in various genres of music to convey feelings of melancholy or introspection.

The other options do not accurately describe the nature of a minor scale. A cheerful sound is typically associated with major scales, which are constructed in a way that often evokes brightness and positivity. The claim that a minor scale consists only of whole notes is incorrect, as minor scales include both whole and half steps. Lastly, while minor scales are used in a range of musical styles, including some dance music, they are not predominantly associated with dance music, which often employs major scales for their more energetic and uplifting qualities.
