     An idea came to me, and I turned off the lights in the studio. In the darkness, I took off my shirt and took

up the cello (大提琴); it was the first time in my life I'd felt the instrument against my bare chest. I'd never

thought about that; music scholars always talk about the resonating properties (共振) of various instruments,

but surely the performer's own body must have some effect on the sound. As I dug into the notes I imagined

that my own chest and lungs were extensions of the sound box; I seemed to be able to change the sound by

the way I sat, and by varying the muscular tightness in my upper body.

     After improvising for a while, I started playing, still in the darkness. I heard the music through my skin.

For the first time I didn't think about how it would sound to anyone else, and slowly, joyfully, gratefully, I

started to hear again. The notes sang out, first like a trickle, then like a fountain of cool water bubbling up

from a hole in the middle of a desert. After an hour or so I looked up, and in the darkness saw the outline of

the cat sitting on the floor in front of me, cleaning her paws and purring loudly. I had an audience again,

humble as it was.

     So that's what I do now with my cello. At least once a day I find time to tune it, close my eyes and listen.

It's probably not going to lead to the kind of comeback I'd be thirsty for-years of playing badly have left scars

on my technique-but I might eventually try giving a concert if I feel up.to it. Occasionally I feel a stab of

longing, and I wish I could give just one more concert on a great stage before my lights blink off, but that

longing passes more quickly now. I take comfort in the fact that, unlike the way I felt before, I can enjoy

playing for myself now. I feel relaxed and expansive when I play, as if I could stretch out my arms and reach

from one end of the apartment to the other. A feeling of completeness and dignity surrounds me and lifts me

up.
