The 'harmonic minor' is so called because it provides the three principal chords of the classical minor key.
This is the reason for the curious combination of minor sixth (the third of the iv chord) and the major seventh (third of the V chord).
The harmonic minor scale uses the same notes descending as ascending.
Here are the teaching videos for the harmonic minor scales in the sharp keys.
