>> So, from this degree that we're going to build our relative minor scale.
So if we take the sharps that belong to D major, F-sharp and C-sharp.
We keep them, but we're just going to start the whole sequence on B.
We get B, C-sharp, D [SOUND]
E, F-sharp, G, A, B.
>> What we got to produce that B minor, was all the
notes of D major, but just rearranged with B as our new tonic.
[MUSIC]
We call this the Natural Minor.
It's the most closely related to D.
Now we mentioned that there's a couple of
different types of minor scale that are in use.
The reasons that we've got a few different variations on that, is partly because of
the transition we made from D to the
relative Minor B, there in the natural form.
Where, where we're only using exactly the notes
of D Major but rearranged from B to B.
And the results of that, is that although we can
start and end on B if we want to, we
could easily, just as easily, end on D and we'd
be back feeling as though D was still our tonic.
[MUSIC]
>> So D really feels the point of which the music has come to rest that
we feel comfortable with this as being the center of the key and the whole note.
And this goes back to what we talked about in
the previous section, whereby it's actually not just the notes that
are available to us, but it's the special relationship that
they have, and the environment, the sonic environment that they create.
And that's inevitably going to pull us back to D.
Listen to this though.
[MUSIC]
>> Now that minor scale had a really different
feeling to the natural minor that we started with.
We only changed one note, but the result of that one change was
to give us a scale that showed us how B really is our new tonic.
[MUSIC]
>> So the note that we changed was the 7th degree.
So instead of an A natural, as we had when we derived the scale
from D-Major, we have an A-Sharp and actually, what we heard was that this.
[MUSIC]
Really led our ears to B, being the new tonic.
And actually the 7th degree of a scale is called the Leading Note.
And we really had this,
[MUSIC]
Raised 7th.
Raised by a semitone, from an A to an A-sharp.
Led our ears to B as our new tonic.
>> So, just to recap from previous lectures, we now know
that the 1st degree of this scale is called the Tonic.
The 5th degree of this scale is called the Dominant and
the 7th degree of this scale is called the Leading Note.
>> And this is one leads our ears to the Tonic.
But don't worry we're going to cover all these note names and the others in week 4.
[MUSIC]
This leads our ears back to the Tonic.
[BLANK_AUDIO]
>> So the scale that we just produced by raising that 7th degree, we
call the Harmonic Minor Scale and it's the one that has a really distinctive sound.
In lecture 4, we're going to talk about Harmony.
We're going to talk about the relationship of chords within a
key and the way that the chords move and progress.
And at that point, it'll hopefully be a little clearer
as to why we call this the Harmonic Minor Scale.
