The illustration above displays a C harmonic minor scale, constrasted against both the major and natural minor scales. Notice the harmonic minor scale differs from the natural minor scale in just one note; the raised seventh. This note contains the strongest color in the scale, in that it carries a certain degree of tension, and should be used with this knowledge in mind. Hanging onto the seventh degree of the scale, then resolving it up a semi-tone to the root is a nice way to create a tension-release scenario when improvising over a minor chord.
