Hi,
I thought your insights and presentation of the material was excellent.. I think illustrating your points with tunes (either yours or others) would help. I'm thinking something like presenting music to define the evocative nature of a piece.... and the presenting lyrics that would underscore that and removing them again.
Certainly, the psychological impact and movement through emotional material would make your point. I'm looking forward to parts 2 and 3 to see how your metaphors hold up...
Very interesting website as well!!!!!!!
