In Western music theory, minor scale may refer to: ⁕any scale that contains, in its tonic triad, at least three essential scale degrees: 1 the tonic, 2 a minor-third, or an interval of a minor third above the tonic, and 3 a perfect-fifth, or an interval of a perfect fifth above the tonic, altogether comprising a minor triad on the tonic note. All minor scales differ from major scales in that the third in major scales is a major third, i.e. one semitone higher than the minor third found in minor scales. In other words, the third scale degree in all minor keys has been lowered one half step, or semitone. ⁕the natural minor scale taken by itself, as the Aeolian scale under Functional harmony. When a major scale and a minor scale have the same key signature, they are relative keys. A natural minor scale has the same notes as its relative major scale, but is built starting from the sixth note of the relative major. ⁕the functional fusion of natural minor, harmonic minor, and melodic minor scales, as is used in Western classical music. A harmonic minor scale differs from a natural minor scale in that the seventh note is raised one semitone. Melodic minor scales raise both the sixth and seventh notes one semitone when ascending, but when descending, the sixth and seventh notes are flattened, producing the natural minor scale.
