Minor Scales: There is a difference...

Our last post discussed the relationship between Major and minor scales. Every Major scale has a minor scale embedded inside of it. You can find that scale by simply staring on the 6th degree of the Major scale.
We call that scale the relative or natural minor scale. This isn't the only type of minor scale however.
Today's post will focus on two variations on the natural minor scale: harmonic minor and melodic minor.

Harmonic minor:
The harmonic minor scale is a simple variation of natural minor that makes a huge difference in sound and function.

Here again is the pattern of the relative or natural minor scale.

Now we'll check out the harmonic minor scale.

You will notice we raised the 7th degree of the scale. This gives us an unusual interval between the 6th and 7th notes in the scale. This interval gives the harmonic minor scale a unique sound and helps explain the function of the scale.

Melodic minor:

The melodic minor scale uses a similar alteration as the harmonic minor scale.

You will notice in melodic minor we raise both the 6th and 7th degree of the scale.
