Tuning - Harmonic Minor, Part 2

First of all, Natural Minor and Harmonic Minor, though similar, are two different scales. The Natural Minor scale contains a lowered 3rd, 6th and 7th relative to the Major Scale (the one we're used to). The Harmonic Minor scale contains a lowered 3rd and 6th, leaving the 7th untouched. This "raised" 7th scale degree creates a powerful leading tone to the root note (B to C, in a C Major Scale, is a half step away... the B yearns to go to C). If you have a piano give this a try to listen to the difference.
