As one of the most popular musical instruments in the world, pianos have seen many changes over the years. From the evolution of their design to the materials used in their construction, pianos have come a long way from their origins in the 18th century. One of the most important aspects of a piano’s construction is its keys, which allow musicians to create the beautiful melodies we all know and love. In this article, we will explore the materials used to make piano keys and their evolution over time.
What material is used for piano keys?
Originally, piano keys were made from ebony and white ivory. Ebony is a dense, black wood known for its durability, while white ivory comes from the teeth of elephants and has a distinct feel and sound. Ivory was prized for its smoothness and was considered the ideal material for piano keys for many years. However, the use of ivory has declined due to concerns about animal welfare and conservation.
What are piano keys made from now?
Today, piano keys are made from a variety of materials, including plastic, resin, acrylic, and composite materials. These materials have been developed to replicate the properties of ivory and ebony while providing more sustainable and cost-effective alternatives. One popular material used today is cellulose acetate, a thermoplastic material that is durable and long-lasting.
According to Steinway & Sons, one of the most prestigious piano makers in the world, their keys are made from a composite material called phenolic, which is a type of thermosetting plastic. This material is highly resistant to wear and moisture and provides consistent performance over time.
Are my piano keys ivory or plastic?
If you have an older piano, it’s possible that your keys are made from ivory. However, it’s important to note that the use of ivory has been restricted in many countries due to concerns about animal welfare and conservation. In the United States, it is illegal to import or sell ivory products that were made after 1976.
If you’re not sure what your keys are made of, you can look for clues. Ivory keys will have a slightly yellow appearance and a texture that is both smooth and slightly porous, while plastic keys will look and feel more uniform. You can also consult with a piano technician or appraiser to help identify the materials used in your piano.
When did they stop using ivory for piano keys?
The use of ivory for piano keys has been in decline for several decades, but many pianos made before the 1950s still have ivory keys. In the United States, the use of ivory for new pianos was banned in 1976 under the Endangered Species Act. It is also banned in many other countries around the world. Today, most piano makers use synthetic materials to create keys that replicate the look and feel of ivory while being more sustainable and ethical.
In an interview with NPR, John Rhodes, the director of manufacturing at Steinway & Sons, explained that the decision to stop using ivory was based on a desire to be more environmentally responsible:
“Steinway has always been very conscious of environmental impact, and we realized that using ivory was not a sustainable practice. We spent many years researching and testing different materials before settling on phenolic, which we believe is the best material for our keys.”
Conclusion: Piano Key Materials and the Evolution of Piano Manufacturing
The materials used in piano keys have evolved over time, from the traditional ebony and ivory to modern synthetic materials. Today, pianos are made with a focus on sustainability, durability, and performance, while honoring the traditions and craftsmanship of the past. Whether your piano has ivory or plastic keys, it’s important to understand the unique qualities of each material and how they contribute to the instrument’s sound and feel.
As we look to the future of piano manufacturing, it’s likely that new materials and technologies will continue to be developed. But no matter what changes come, the piano will always be a beloved instrument, cherished for its beauty and the emotions it can evoke.
