Intervals - part 2 (minor third)

So yesterday we started working with intervals from the Major scale. Today I want to take a little time going over intervals from the minor scale. First, let's review the formulas for figuring out the scales:

Major Scale
W-W-H-W-W-W-H

Minor Scale
W-H-W-W-H-W-W

So, take a look at your keyboard and take a minute to figure out the notes of the C Major and C Minor scales. Let's pay special attention to the first five keys of each scale. What is the only key that is different between them?

Now, let's play the first and third notes of C Major together. What is this interval called?

Now let's play the first and third notes of C Minor. What do you think this interval is called?

Let's take a minute to listen to a famous beat that uses just two intervals (a 4th and a 3rd) from the F Minor Scale: link.   

So for your assignment, please do one the following:

1. Keep working on your beat from yesterday and add a new part using a minor 3rd. For example, if you were working on the verse for your song yesterday, work on the chorus today and put a minor 3rd into it. Save it.
2. If you finish this song and don't feel like adding anything, try to remake the beat for Still D.R.E.  Listen to it again and pay attention to the instruments being used, the tempo etc.
