Tuning Devices

[Andrew & Rebeca Anderson]

---------------------- multipart/alternative attachment
The problem with guitar tuners is that they are not intended for the wide 
harmonic range of a piano.  They do not accommodate a piano's inharmonicity 
at all either.  I've been called in to tune a baby grand piano that a 
guitarist had tried to tune with a wrench and a guitar tuner.  The 
temperament octave was compressed and the octaves were terrible--no stretch 
etc.  You can use them to set a temperament in a larger piano acceptably 
for non-tuners, but when you get into the little monsters you will run into 
clashing intervals in the temperament octave.
If you are going to use an ETD, I recommend getting one that is intended 
for pianos or they will end up being more work to correct than any work 
they could save you.  If you have a portable computer with a soundcard, 
Tunelab97 is cheap enough.

My humble, blunt opinion,
Andrew
