Answer:
A. Three
Step-by-step explanation:
The 3 types of minor scales are the following:
- Natural minor scale.
- Harmonic minor scale: The 7th is raised by a half-step.
- Melodic minor scale: Both the 6th and 7th are raised by a half-step when ascending, then go back to natural when descending.
Natural minor scales are actually formed starting on the 6th degree of a major scale, we call this a "relative scale". For example, let's say we have the C Major scale:
- C - D - E - F - G - A - B - C
We can obtain a minor scale by starting on the 6th, which is "A" in this case:
- A - B - C - D - E - F - G - A
Of course, we can turn it around and obtain a major scale starting on the 3rd degree of a natural minor scale, let's look at another example, this time with the C natural minor scale
- C - D - Eb - F - G - Ab - Bb - C
Now, if we start from the 3rd degree, we obtain its relative major scale, which is Eb Major in this case:
- Eb - F - G - Ab - Bb - C - D - Eb
