From both ways of listening helpful results may accrue, but by no means the greatest. Music is far beyond words, and in attempting to translate it into these we miss its musical meaning, the best that is in it. As listeners we derive our highest aesthetic and intellectual satisfaction from the ability to follow, even anticipate, the composer's intention, now finding our expectations fulfilled, now being agreeably disappointed. Failure to catch the opening phrase and preliminary rhythms of the composition makes it impossible to appreciate the tonal forms into which they develop. Nor may the mind linger over any one part, if we would grasp the work as an unbroken whole. That musical creation alone can afford the noblest delights that prompts and rewards the act of thus closely following the composer's thought. An instance of absolute knowledge of music appears in an anecdote told of Johann Sebastian Bach. When he was present at the performance of a fugue and one of his two most musical sons was with him, he would, as soon as the theme was heard, whisper what devices and developments he thought should be introduced. If the composer had conformed to his idea of construction he would jog his son to call attention to the fact. Otherwise, his exceeding modesty and reverent comprehension of the difficulties of the art made him the most lenient of critics. Few have reached the luminous heights this master of masters trod. Even a well-cultivated ear and taste may often be baffled by the intricacies of a fugue, symphony or other great work of musical art heard for the first time. The best listener beyond the pale of genius will at times feel as one astray in a labyrinth of beauty to which for the moment no clue appears. A single representation will rarely suffice to reveal the full worth of a masterpiece of music. By hearing it often, by admitting it, or some reproduction of it, to our own fireside, we will become familiar with its contents and learn truly to know it. Those who are fortunate enough to have been surrounded from childhood up by the choicest gems of the tonal language, and whose minds are of the deceptive order, will insensibly attain a refinement of taste and delicacy of perception no learned dissertation on music could afford. At the same time, an acquaintance with the materials and elements of which the art is composed and with the laws that govern them, is essential to enable even one who has heard much to gain the complete enjoyment that comes from understanding. Confident as we are that Prometheus captured his fire from Heaven, we ought to learn something of its attributes before we accept it at his hands, that we may be able to distinguish a true spark of the divine flame from a phosphorescent will-o'-the-wisp.
