What is the difference between piano strings and piano wires?

"Piano strings" and "piano wires" are terms often used interchangeably, referring to the same component in a piano. The strings or wires are made of high-tensile steel and are responsible for producing sound when struck by the piano hammers. The term "strings" emphasizes the musical nature of this component, while "wires" highlights the material's strength. The strings or wires vary in thickness and tension, determining the pitch of each note. Modern pianos typically use a combination of plain steel and wound steel strings. So, in essence, there is no substantial difference between piano strings and piano wires—they refer to the same essential element in a piano.
