Okay, I went through them and this is what I have come up with. I also looked through some other Czerny and found some studies to work up to other studies

... he he.
Anyway, I don't own all of the Scarlatti Sonatas, but found some ones that address some similar issues. I will try to look through some of his other sonatas and see if I can find anymore to add.
