Evolution of a song called Usva

Our professor was Jeff Friedman. Among students I think he had a reputation of being a bit strict at times. But I never understood what the problem was. If you just did your stuff and were interested in what you were doing, Jeff offered kindly all the support you could ever need. And wasn't it only fair to assume that if you chose Jazz Composition as your major, you should be interested in studying it too? I personally liked and respected his approach to teaching music and composition very much.
