Plug in the simplest stereo/cassette player you can find, and gather a stack of new or used blank cassettes. Lie stretched out, face down on the floor, feet pointed away from the stereo. Tune to any radio station and put in a tape. Press the buttons for pause and record/play, then wait, and wait, and wait for a break in the music, or to catch the first note of a song you know, index finger poised above the pause button. Wait for hours. Wait all through the rainy afternoon.
