What You'll Learn
Early piano key materials
The earliest piano keys were made from a variety of materials, each chosen for its unique properties and availability. One of the primary materials used was ivory, sourced from the tusks of elephants. Ivory was prized for its smooth texture, durability, and beautiful appearance, making it an ideal choice for the white keys of early pianos. However, the use of ivory had significant ethical and conservation implications, leading to its eventual decline as a preferred material.

In the late 19th and early 20th centuries, manufacturers started experimenting with synthetic materials to replace ivory. One of the earliest synthetic alternatives was celluloid, a type of plastic derived from cellulose. Celluloid keys offered a similar appearance and feel to ivory, but they were more affordable and did not require the harvesting of elephant tusks. However, celluloid had its own set of problems, including a tendency to warp and crack over time.
The development of new plastics in the mid-20th century led to further innovations in piano key materials. Materials like Bakelite and later, high-quality thermoplastics, became popular choices for piano keys. These plastics offered improved durability, resistance to warping, and a more consistent quality compared to earlier synthetic materials. The transition to plastic keys marked a significant shift in piano manufacturing, allowing for more affordable and accessible instruments.
Today, modern pianos typically feature keys made from high-quality plastic materials, which provide a good balance of durability, aesthetics, and cost-effectiveness. While some high-end pianos still use traditional materials like ivory and ebony, the majority of pianos produced worldwide utilize plastic keys. This change has not only made pianos more affordable but has also contributed to the conservation of endangered species like elephants.
