• We have a duty towards music; namely to invent it. ...Invention presupposes imagination but should not be confused with it. For the act of invention implies the necessity of a lucky find and of achieving realization of this find. What we imagine does not necessarily take on concrete form and may remain in a state of virtuality; whereas invention is not conceivable apart from its actually being worked out.
