Sorry about the part-crossing, I should be more careful in the future! I have time for my homework after work only when my brain's already "out-of-order".
You shouldn't be impressed about the ii6/3 imperfect cadence, since you was who mentioned it in your 2nd lesson. I've just tried it, and I think it sounds best!
Thanks for the instructions, it makes many things clear for me.
