The making of music is the everlasting and inescapable act of creation.  The life of music is reborn at every singing.  It actually doesn't exist on paper, but in time and in sound.  It has existed in the composer's spirit, but at each singing it seeks a new life.  And the performer, though his craft is that of representation and his proper approach that of humility, cannot escape the responsibilities of creation.  And that has some moral reference.

-- Robert Shaw
