The power of music, whether joyous or cathartic, must steal on one unawares, come spontaneously as a blessing or a grace. “The Arts are not drugs,” E. M. Forster once wrote. “They are not guaranteed to act when taken. Something as mysterious and capricious as the creative impulse has to be released before they can act.”
Also true. There have been plenty of times in my life where I expect a certain refrain, song, or concert to lift my spirits…and then it doesn’t. That’s the whole deal with performing arts — you’re a part of the experience, too. And there are other people with other feelings tied to that experience.
Just because we pay to share in that experience does not in any way guarantee us a right to “maximum enjoyment” of said experience.
Such is art.
