But one can get so hung up on a type A definition of perfect that the comparison of any two tunings becomes meaningless. Soon we'll be invoking the Heisenberg uncertainty principle to declare that we can't both measure and know where the pitch on any given note is at the same time. Exact repeatability of tunings is clearly an advantage for machines where tunings can be saved and even where they can't, measurement error and (perhaps) humidity changes notwithstanding. The experiment for this is quite simple really. Put two pianos side by side that are the same make, model, scaling, and have someone tune both by ear and someone tune both with an ETD. Measure the two pianos and compare how identical the tunings are. Do that with a large enough statistical sample to make it meaningful and I would hypothesize that the aural tuner would exhibit a wider variation. I'm not saying it would be an unacceptable variation, it might well still score 100% on a tuning test. But that's not the question. The question is how identical will the tunings be. That one particular aural tuner you happen to know can hit your calculated and custom tuning marks is not evidence of parity. > > The question of whether the same is better or not is a different question and not really relevant. A saved tuning, as others have pointed out, does not mean that the tuning is not altered later as one customizes it more to their liking. The difference is that on a saved and refined tuning you have the benefit of the accumulated benefit of repeated examinations without having to start from scratch every time. The obvious benefits exist when tuning two or more pianos in unison. > > David Love > www.davidlovepianos.com > -- Duaine Hechler Piano, Player Piano, Pump Organ Tuning, Servicing& Rebuilding Reed Organ Society Member Florissant, MO 63034 (314) 838-5587 dahechler at att.net www.hechlerpianoandorgan.com -- Home& Business user of Linux - 11 years
