Re: Inexpensive hearing aids
Yes, you might do better with a lute, classical guitar, or something else which
used gut strings. Then again, we're now crossing from the issue of instrument
scaling production of harmonics to harmonics produced by string types. Even for
pianos along an electronic piano or acoustic piani with pickup would produce an
entirely different set of harmonic structures. Thanks for pointing this out.
