Listening with the "heart"
In 2004 the Taipei Parents' Association for the Visually Impaired set up a piano tuning class for visually handicapped people. Chien Hsiang-chi never thought she could make a living out of piano tuning, she just thought she would learn this skill to guarantee her own piano would always have a nice, clear tone that was just right. And so she moved north, far from Nantou, and began to live on her own and study piano tuning.
The first step in tuning a piano is to move the 20-kilo soundboard (even heavier for imported pianos with their original soundboards). For Chien, not only was this a question of weight, "I was afraid of crushing my foot!" she says. She then feels out the internal structure of the piano, gets out 20 or 30 items from her "treasure chest," which include a tuning fork, adjustable tuning bar, damper felt pads, tuning wrench, strike hammers, rubber wedges.... She has to find the right tool and get it in the right position, and use her keen sense of hearing and an accurate and precise amount of force before she is able to adjust the hundreds of components and correct the notes that are out of tune.
Chien is especially fond of the soft feel of the felt hammers. But with one end connected to the keyboard, the other end striking the piano wire to set it vibrating, the hammer is the key to determining the tuning and quality of the sound. Just getting one note wrong can ruin the whole job.
When she first started, Chien would misadjust a tuning pin or set the hammer angle wrong because she could not see. She would then have to spend hours, several times that of the average person, to get things right just by feel. And once her fingers were cut badly by the soundboard catches. To keep up her progress, Chien regularly practiced in the association's tuning classroom, working hard to commit to memory the "feel" of the best tunings she had done and storing them in the back of her mind. Each practice session would last five or six hours. To overcome tuning errors, she recorded her tunings and listened to them over and over again to pick out the mistakes. She also listened to tunings done by fellow tuners, comparing them and integrating them with her own. After 720 hours of practice, her success rate reached 96%, and before long she got her state license and became a bone fide piano tuner.
Currently there are some 50,000 visually handicapped people in Taiwan. Their eyes may be blind, but not their hearts. They need more varied career opportunities and training so that they can realize their self-potential and contribute their expertise to society.
