“Don A. Gilmore, an amateur piano player and professional engineer from Kansas City, Mo, has developed an electronic system that he says could allow pianists to tune their own instruments at the touch of a button.” The system relies on heated strings, electricity, and an elaborate computer program which ‘remembers’ an initial tuning and can replicate it under almost any circumstances. The self-tuning models won’t be cheap, but then, neither are piano tuners.
