Wolfgang,

I apologize if my attempt at humor seemed dismissive--re-reading, I tend to come off as anti-scientific, which I certainly am not.   

In the study of composition, there is an emphasis on creating and resolving tension-- some musical elements establish tension and some resolve it--elements of both kinds are necessary to create a sense of movement in the music--I think that it is important to understand that this process, the creating and resolution of tension, is the one that needs to be examined, not simple the concept of what might seem "pleasing" to the ear--
