After careful review, I've decided to almost entirely skip Chapter 8. After reviewing sample AP tests, I don't see anything in them regarding species counterpoint.
I've put up some EMT assignments which will help train you on modes, and help you practice a bit of 1st Species Counterpoint. Even though Counterpoint isn't explicitly a part of the test, the principles you apply to do that EMT won't go away & will help us understand the development of Tertian Harmony.
That'll be enough Chapter 8, I think.
We will dive right into Chapter 9 tomorrow, which will absolutely be an important part of the AP test. You will the following Chapter 9 workbook assignments, due after Thanksgiving:
A (1-3 only), B, C, E (1-6 only)
