[pianotech] aural vs edt

[Porritt, David]

Israel:

If Dr. Sanderson considered the Accutuner as an Electronic Tuning Aid I'm curious as to why he promoted the idea of starting at A0 and working up.  Clearly there's no way to do any interval checks in the bass this way as there are no "tuned" notes above them to use as checks.  

When I got my first ETD I did this for a very short time before I realized that limitation.  Now I tune in a pattern resembling aural tuning so I can make those checks.  The idea of A0 & up has always mystified me (well, except for a pitch raise where you don't need checks).

Apropos of these remarks by Matthew and Conrad, it might be useful to 
mention that Dr. Albert Sanderson (who invented the entire field of 
generating tunings based on sampled "stretch" factors) always referred 
to the Accutuner (and its predecessor the Sight-o-Tuner) as "Electronic 
Tuning Aides". I believe that the semantic difference is very important. 
The term "ETD" is very unfortunate, in that it does not accurately 
describe the inventors' intention - even though they surely bank a lot 
of money off people who use them not as intended... 

Al  always stressed the need for aural checks and tests when using his 
devices and was a top-notch tuner himself (even though his primary 
profession was engineering and electronics). I heard him say often that 
a top aural tuner could tune a piano better and faster than one 
dependent on a box. I don't know if the "faster" part still applies in 
the case of electronically-assisted top-notch aural tuners, but people 
who cannot hear what they are tuning are not in a position to argue with 
the "better" part - when pronounced by the inventor of the machine they 
may be using as the sole arbiter of their tunings...
