... to say sorry the newer posts have been a bit delayed. There are a lot more on the way. I also want to emphasize that in this exercise in particular ALL the solutions are worth listening to, even the "bad" ones, because there are so many possible sound combinations here, that it's important to learn what they sound like. Some of the possibilities in the coming solutions are not good as harmonic *backgrounds*, but could be quite valuable in other circumstances, where something more colorful is required.
