In Reply to: Musical instrument tuners (sound frequency comparison) posted by Andrew Freer on 08/27/00 at 3:25 PM:
I believe that such devices are on the market. My father-in-law, a retired music teacher and violinist, has a device something like this. Try looking for a web site using "musical instrument tuners" as keywords into a search engine and perhaps you'll find what you want.
One caution though. Be aware of the concept called "Pythagoras' Comma". Violinists like to tune to perfect pitch, but pianos cannot be tuned that way; they have to be tuned to a tempered scale. Depending on which instrument(s) you are playing, your choice of tuner may vary.
If you need more information on the Comma, I can write it out for you although it would take a while to do. Let me know if you need me to.
