This 1926 Mason & Hamlin Model AA is a spectacular example of American piano building at its absolute zenith. During the 1920s, Mason & Hamlin (based in Boston) was widely considered the only true rival to Steinway, with many technicians and artists of the time considering them the superior instrument due to their innovative engineering and massive construction.

The Tension Resonator (Crown Retention System): The most defining feature of this Mason & Hamlin is the patented Tension Resonator. This heavy, spider-like steel structure is bolted to the wooden rim underneath the soundboard. It locks the rim in place to ensure the “crown” (the arch) of the soundboard never flattens over time. This engineering marvel is why 100-year-old Mason & Hamlins often retain a more powerful, resonant tone than other vintage pianos.

Model AA Performance: At 6’4″, the Model AA is a professional-sized grand that produces a sound far larger than its dimensions suggest. It is famous for its “Orchestral” tone—a deep, thunderous bass that rivals 7-foot pianos and a thick, singing treble. The rim of a Mason & Hamlin is significantly thicker than almost any other piano, which reflects energy back into the soundboard, resulting in incredible sustain and projection.

Aesthetic and Build Quality: Finished in a beautiful Satin Walnut, this piano showcases the craftsmanship of the pre-Depression era. The wood grain is rich and warm, providing a sophisticated look that serves as a stunning centerpiece for any room. The heavy construction and use of old-growth tonewoods from 1926 provide a structural integrity that modern manufacturers struggle to replicate.

Investment Opportunity: At $5,999, this piano is priced lower than many entry-level, mass-produced digital or upright pianos. However, it offers the performance of a world-class professional grand. While it is a vintage instrument, the “bones” of a 1926 Mason & Hamlin are among the best ever made, making it a perfect choice for a serious player on a budget or a candidate for future high-end restoration.

Ideal For:

• Serious Pianists: Seeking a professional 6-foot+ grand with massive power and tonal color.
• Collectors: Who appreciate the engineering and history of the Boston-era Mason & Hamlin factory.
• Churches and Studios: Looking for a professional-grade instrument with significant projection for a fraction of the cost of new.

Comparison to New

New Mason & Hamlin Model AA (6’4″):

• MSRP: Approximately $85,000 – $105,000 (depending on finish and options).
• The Difference: Modern Mason & Hamlins are still built in the USA to very high standards, including the Tension Resonator. However, a new one requires a massive six-figure investment.
• Value Analysis: At $5,999, this 1926 model is priced at roughly 6% of the cost of a new one.

Why Choose the 1926 Model? Beyond the nearly $90,000 in savings, the 1926 “Golden Era” Mason & Hamlins are legendary for their heavy rims and the specific quality of the Boston-sourced spruce used in the 1920s. While a new piano offers modern action parts and a warranty, the 1926 AA provides a level of historical prestige and a “massive” tonal character that defines the golden age of American piano manufacturing. It is arguably the best “performance-per-dollar” value available in the used grand piano market today.
