josepp, could you please define "parallel" and "paralleling"? I do not know what the term means, yet you encourage me to avoid it. You obviously have a lot of musical knowledge, e.g. what you wrote about the ii-V changes. A lot to explore, and I thank you. I may be simply ignorant, but I do not know your terms, and I would like to understand exactly what you are talking about. Thanks, BlueJay
