Hi Pat We are posting a new response as during the move to a higher grade server, we accidently lost the response we had originally offered. What a fine contribution to the conversation! Your remarks brought to mind a practice that our friend Michael Colgrass uses in teaching singing. He has the singer sing standing on his or her head. The tonals difference are startling! BTW, Pat, we have no objections or difficutlies with applications. Indeed, without applications, what would the point of modeling be? What we object to is exclusively applications - for reasons presented in Whispering. All the best, Carmen and John
