I am not sure which thread you are talking about, Susan--also, I am also not quite sure what Frank's comment about not being able to teach anyone anything means--I don't think it relates to the mechanics of playing, which are simple enough to lay out, or to the structural/theoretic aspect of it, which can be communicated, but he may be more concerned with the process that takes players from simply repeating what someone has showed them, to making it their own personal expression--
