what is the order of difficulty for the Bach inventions? i saw a post for the WTC on here somewhere, but what about the Inventions? i'm going to be teaching a former student of mine (she was fairly advanced when I taught her), and I am thinking of giving her Bach's Invention #1 (she can't take lessons until the fall), and having her see what she can do with it this summer, on her own. that way, I could see where she is at, and i'm curious how she would play Bach. he hasn't had lessons since she took lessons from me, and stopped about 12 years ago (had to raise kids), but she continued to play at church. Any suggestions? Thanks!!
