If you go to Indiana University or Juilliard to study "classical" music or go to Berklee to study jazz music, will you be taught different theory? Would a theory textbook for "classical" studies differ in certain respects from a jazz theory textbook? Or is the theory fundamentally the same, but how it is applied is different? I'm thinking in terms of the drastic difference between a jazz musician's heavy emphasis on improvization and a symphony orchestra's strict adherence to what has been previously composed. And what about jazz "compositions" such as Duke Ellington's "Black and Tan Fantasy." Was he following classical theory in composing and arranging that music or did he follow jazz theory or--are the two the same? I was just wondering about this. Also wondering...if for music to break through to some significant new level or new form, would someone have to revise the concepts of present day theory, be it classical or jazz?
