In the simplest terms, there are two primary emotional qualities in music: major and minor. The major quality, as heard in the major scale, is almost universally perceived as "bright" or
"happy" and forms the basis of a large number of melodies in a great variety of styles. The minor quality, on the other hand, is usually perceived as "dark" or "sad", a quality reflected in minor scales. There are several different versions of minor scales, but the essential difference between the major and minor qualities comes down to a single note: the third scale degree. The major scale has a major third degree (whole step), while all minor scales have a minor third degree (half step). This small difference in interval quality, and its resulting emotional effect, is one of the most powerful in music.
