Hi Ning, Your point is well taken about communicating with you before posting my comments on the forum. I apologize for not doing so. I do believe, however, that the forum is an appropriate place to post ideas on how to improve our presentations. My comments were not so much directed at you but were rather intended to encourage PTE presenters generally to strive towards harmony between the visual and the audio portions of presentations. I see that on the substance of the issue, we are in agreement. Perhaps my problem is that I have recently seen Les Choristes and could not get the choirboys out of my mind when listening to that music! I agree with your comments about the universality of music. We should not be bound by rigid formulae and should remain free to experiment. By the way, I do have two PTE presentations on the site: Canoe Country and A National Park Struggles to be Born. Feel free to comment. Roger
