If you’ve ever had the opportunity to move an old upright piano, you’d likely agree that they are incredibly heavy. While modern technology has given us lighter and more portable pianos, these historical relics remain as heavyweight champions. In this article, we will explore the reasons why old upright pianos are so heavy and why this characteristic is an integral part of their design.
1. Solid Wood Construction:
One of the primary reasons old upright pianos are heavy is their construction. These pianos are typically crafted from solid wood, including hardwoods like oak, walnut, or mahogany. The use of high-quality wood results in a sturdy and robust frame that adds substantial weight to the piano.
2. Cast Iron Plate:
At the heart of every piano, including uprights, is the cast iron plate. This plate is responsible for sustaining the incredible tension of the piano strings. In old upright pianos, this plate is often made from thick, heavy cast iron, which contributes significantly to the overall weight of the instrument.
3. Thick Strings and Soundboard:
Old upright pianos feature thick and substantial strings, which are essential for producing rich and resonant tones. The soundboard, which amplifies the vibrations of the strings, is also constructed with thicker and denser materials, further increasing the weight.
4. Multiple Layers of Wood:
The soundboard and the inner frame of an upright piano are typically made of several layers of laminated wood. This multilayer construction provides structural stability but also adds to the overall heaviness of the piano.
5. Dense and Heavy Keys:
The keys in older pianos are often crafted from dense and solid materials. Ivory was historically used for the keytops, which, while adding to the piano’s aesthetics and playability, also contributes to its weight. Even in the absence of ivory, modern keys are still constructed from substantial materials.
6. Complex Mechanisms:
Old upright pianos have intricate internal mechanisms, including hammers, dampers, and the action assembly. The combination of these elements adds considerable weight to the piano. These components are crucial for producing nuanced and expressive sounds, and while they add weight, they are fundamental to the instrument’s musicality.
7. Thick Cabinet and Veneer:
The outer cabinet of an old upright piano is typically constructed from thick wood, and the wood veneer can also be substantial. The combination of these materials contributes to the piano’s bulk.
8. Designed for Stability:
Lastly, the substantial weight of old upright pianos is intentional. The weight provides stability and prevents the instrument from shifting or wobbling during playing. It also helps maintain the piano’s structural integrity over many years.
Conclusion
Old upright pianos are renowned for their durability, rich sound, and timeless beauty. The weight of these pianos, often viewed as a challenge when moving or transporting them, is a testament to their robust construction and enduring quality. While modern technology has allowed for lighter and more portable instruments, the heavyweight nature of old upright pianos is an essential part of their charm, resonating with their historical significance and craftsmanship.
