MTed has asked me to tell you all that he is glad if his comments were helpful. He also takes it as a kindness that someone remembered this post of his from last year, and appreciates that it was refreshed when the questions about range came up again.

He keeps pointing out that anyone who has studied a little music theory would give you the same answers that he does, which I suppose is true, but his explanations seem to be a little easier to make sense out of than most.

You are lucky that he has written this stuff out, though, because once he starts talking about it, it is hard to shut him up.
