There are enormous fields of knowledge quite outside literature which will yield magnificent results to cultivators. For example (since I have just mentioned the most popular piece of high-class music in England to-day), I am reminded that the Promenade Concerts begin in August. You go to them. You smoke your cigar or cigarette (and I regret to say that you strike your matches during the soft bars of the "Lohengrin" overture), and you enjoy the music. But you say you cannot play the piano or the fiddle, or even the banjo; that you know nothing of music. What does that matter? That you have a genuine taste for music is proved by the fact that, in order to fill his hall with you and your peers, the conductor is obliged to provide programmes from which bad music is almost entirely excluded (a change from the old Covent Garden days!). Now surely your inability to perform "The Maiden's Prayer" on a piano need not prevent you from making yourself familiar with the construction of the orchestra to which you listen a couple of nights a week during a couple of months! As things are, you probably think of the orchestra as a heterogeneous mass of instruments producing a confused agreeable mass of sound. You do not listen for details because you have never trained your ears to listen to details. If you were asked to name the instruments which play the great theme at the beginning of the C minor symphony you could not name them for your life's sake. Yet you admire the C minor symphony. It has thrilled you. It will thrill you again. You have even talked about it, in an expansive mood, to that lady--you know whom I mean. And all you can positively state about the C minor symphony is that Beethoven composed it and that it is a "jolly fine thing." Now, if you have read, say, Mr. Krehbiel's "How to Listen to Music" (which can be got at any bookseller's for less than the price of a stall at the Alhambra, and which contains photographs of all the orchestral instruments and plans of the arrangement of orchestras) you would next go to a promenade concert with an astonishing intensification of interest in it. Instead of a confused mass, the orchestra would appear to you as what it is--a marvellously balanced organism whose various groups of members each have a different and an indispensable function. You would spy out the instruments, and listen for their respective sounds. You would know the gulf that separates a French horn from an English horn, and you would perceive why a player of the hautboy gets higher wages than a fiddler, though the fiddle is the more difficult instrument. You would _live_ at a promenade concert, whereas previously you had merely existed there in a state of beatific coma, like a baby gazing at a bright object.
