Before modern plastics, what material was traditionally used to cover the white keys of high-quality pianos?
Tap your pick
For centuries, the white keys of premium pianos were topped with thin strips of real elephant ivory, valued for its smooth texture and ability to absorb sweat. Due to conservation efforts and international bans on the ivory trade, manufacturers transitioned entirely to high-tech plastics in the late 20th century. Modern synthetic materials are designed to mimic the tactile feel of traditional ivory. Photo: Jastrow, Wikimedia Commons, Public domain.
