"One is reminded of those masters of musical improvisation whose hands the listener would also like to credit with divine infallibility although here and there they make a mistake as every mortal does. But they are practiced and inventive and ready at any moment to incorporate into their thematic order the most accidental tone to which the flick of a finger or a mood has driven them, breathing a beautiful meaning and a soul into an accident."
