Though I may have the pleasure of discovering musical processes and composing the musical material to run through them, once the process is set up and loaded it runs by itself. If the shoe fits, wear it. As to whether a musical process is realized through live human performance or through some electro-mechanical means is not finally the main issue. One of the most beautiful concerts I ever heard consisted of four composers playing their tapes in a dark hall. It is quite natural to think about musical processes if one is frequently working with electro-mechanical sound equipment.
All music turns out to be ethnic music.
Musical processes can give one a direct contact with the impersonal and also a kind of complete control, and one doesn't always think of the impersonal and complete control as going together. I mean that by running this material through this process I completely control all that results, but also that I accept all the results without changes. John Cage has used processes and has certainly accepted their results, but the processes he used were compositional ones that could not be heard when the piece was performed. The process of using the I Ching or imperfections in a sheet of paper to determine musical parameters can't be heard when listening to music composed that way. The compositional processes and the sounding music have no audible connection.
