1909 Mason & Hamlin AA WAL | 18385

The Mason & Hamlin Model AA is a 6-foot-4-inch (193 cm) parlor grand piano celebrated for delivering a rich, powerful, and large sonic capacity often found in significantly larger instruments. These American-made pianos are renowned for their “overbuilt” construction, which features thick hard rock maple rims and the proprietary Tension Resonator, ensuring superior durability, stability, and a warm, sustaining tone. The characteristic Mason & Hamlin tone is typically American—lush, singing, and powerful, often described as having a more powerful bass and clearer treble than a Steinway. Beyond structural strength, tuning stability is enhanced by the patented Screw Stringer mechanism, which attaches the wires to vertical “hooks” supported by the iron harp, an innovation claimed to reduce the need for tuning by 75 percent. Furthermore, all new Mason & Hamlin pianos now incorporate the Wessell, Nickel & Gross (WNG) composite action, utilizing carbon-fiber parts predicted to have a minimum life expectancy of 100 years.
