Richard brought up some questions about modes of the soundboard and many other related topics. Has someone brought up the "five lectures" yet? I don't think this answers all of your questions, but I ran across this, which is part of the "five lectures": http://www.speech.kth.se/music/5_lectures/conklin/howdoes.html There are some other interesting things in these lectures, too, related to this discussion.
