I recently had the pleasure of rebuilding an Emerson upright piano from 1916. This particular piano had been in one family for the past 100 years. As is often the case, a treasured family piano still looks wonderful, so my work on the case was simply to clean, polish and replace some missing knobs. The musical instrument, inside, however got a rather complete make-over! With age it really wasn't sounding good or playing well.
Now when we open up the case of the 1916 Emerson, we see a new piano. How does it sound? Well the customer says it's wonderful! And I believe it's very close to what it was in 1916.
