umm.. i've never heard of any of these stores, so i checked them out: Crutchfield, J & R Electronics, and Best Buy. but it doesn't seem like any of them sells actual pianos or violins. also i didn't see any sound recording/analysis software programs.
a sound store would sells these.
any specific stores (online or off) that i could continue searching in? now in Any of the 195 countries on planet earth.
