"Music begins to be 'manipulated' the moment it is interpreted by a conductor or a soloist and played by an orchestra in a hall with a specific acoustic. All these factors 'manipulate' music and so does the fact that I ask the oboe please to play more piano. And you are manipulating the orchestra for one reason only: to get the sound you want. In the recording studio you are using the equipment at hand for exactly the same reason."
Herbert Von Karajan
