It is only economically viable to build premium pianos in small numbers. A good example is Steinway & Sons, who has thrived for so long because they build a product with such incredible value that the big corporations see no sense in trying to compete. It has proven difficult to be small and successful in piano building, but it is impossible to build great pianos in large quantities. Steinway is the singular example of success manufacturing pianos on a small scale, but they have had over 150 years to figure it out.
There are a handful of companies that are trying to ride Steinway’s coattails, building low- to mid-quality pianos in the United States. Unfortunately, economies of scale favor overseas production and these pianos prove to be mediocre at best and with virtually no resale value. Whatever your position on buying American, the fact is you will find better pianos for less money that are made in Asia.
If you want to buy a quality piano that’s made in the USA, Steinway & Sons is the best value, although they cost a little more than the others.
