According to the Piano Technicians Guild, there are 10,000 tuners for America’s 18 million pianos. And half of them now use a computer and software such as CyberTuner to adjust strings to the correct pitch. There’s ongoing debate in the tuner community over which method is more effective. Some even say that electronic tuners should be used to save the ear for more fine adjustments. With an electronic tuner and little training, maybe anyone could become a piano tuner, but there’s still the need for experience and learning how and when to make fine adjustments.
