Built for durability, Mason & Hamlin pianos have been historically recognized as the world’s costliest piano to build. Whether it’s hard rock maple rims, white spruce soundboards, full perimeter, sand cast plates, chrome tuning pins, quarter sawn maple pin blocks and bridges, or even hinges and screws, only the finest available, most accurate, highest quality materials have been used to build a Mason & Hamlin piano. Ideal equilibrium moisture content levels are achieved by carefully monitoring the conditioning of each species of hardwood used on a Mason & Hamlin piano.
