Hello list.. Sarah Fox said: "I don't see how the properties of an impulse delivered to a resonant system can alter the resonant frequencies of that system. The system will only resonate in response to the spectral energy in the impulse that corresponds to its natural resonant frequencies. If the hammer does not deliver (or delivers but damps) the higher frequencies to which the system could potentially resonate, the system will not resonate at those frequencies. However, that's not to say that the resonant frequencies have shifted towards a harmonic relationship with the fundamental. A system will not freely resonate to frequencies to which it is not tuned -- although it can be driven at "off-frequencies" with continuous input of energy." There is yet another parameter to be put into the "melting pot". That of Sympathetic Vibrations within the piano as well as any "Aliquot" or "Duplexing". All these things add (hopefully!) to the overall quality of the acoustic piano - and these are things which cannot be replicated by any purely electronic piano. So in this the Piano stands supremely alone. Has anyone got a spare flame-suit? Regards Michael G (UK)
