Well I disagree with your professor. He must follow the John Cage school of thought. *** American bastards, always messing things up.
John Cage would argue that footsteps are music because they could be "organized." What a moron. No wonder nobody listens to John Cage. I hate him.
OK - and, believe me, I'm no proselytizer for the Cage cause myself - but Cage is only one kind of American composer. In the past hundred years or so, America has given us composers as diverse as Ives, Reich, Feldman, Copland, Sessions, Diamond, Nancarrow and Carter and hosted the Frenchman Varèse (almost all of whose surviving work was written during his last 45 or so years there).
I don't hate Cage. I just don't listen to him (except recently when a composer that I respect listened to a recent performance of Sonatas and Interludes and found to his astonishment that he actually enjoyed it - learning of this prompted me to make myself listen to it once more and, frankly, if I never hear it again, it'll be too soon). Why don't I listen to Cage any more? Simply becuase nothing I've ever heard from him has done anything for me whatsoever. Likewise with most of the work of the Amercian minimalists. I just don't want to be confronted most of the time with what strikes me largely as emptiness when listening to music. I want to be excited, upset, moved, invited to concentrate, etc. There's usually more substance to be found in a few bars of a Sessions symphony or a mature orchestral work by Carter than in whole hours of this kind of stuff. But that's only my personal opinion. It doesn't make me "hate" anyone. Nor does it make me contemptuous of Americans.
Now come on - this America-bashing is getting alarmingly close to the "death to America" chanting that is nowadays expected to follow Friday prayers in Teheran!
Best,
