Piano wire was used in certain execution methods, such as hanging from a beam. Throughout history, one of the execution methods involved using piano wire on a hanging beam. Piano wire does not stretch and is also very sharp, meaning it would create prolonged suffering for the condemned. But why was this used?
Piano wire, a high-carbon steel wire known for its strength and thinness, has been employed in various contexts, including musical instruments and industrial applications. In historical execution practices, it was occasionally used as a ligature or noose material.

One documented use was during World War II by Nazi Germany, particularly after the July 20, 1944, plot to assassinate Adolf Hitler (Operation Valkyrie). Hitler ordered the conspirators to be executed using piano wire on meat hooks or beams, with the process filmed. The wire’s non-stretch property prevented a quick neck snap, leading to death by strangulation. Its sharpness could cause additional injury during the process.

The choice of piano wire was due to its material properties: high tensile strength and minimal elasticity. This resulted in a slower process compared to traditional ropes. In the Nazi context, it was selected for the executions of plotters like Claus von Stauffenberg and others, with the films shown to Hitler. The method was also reported in other instances, such as by Italian partisans or in fictional depictions like in The Godfather.

Piano wire was used in execution methods due to its properties of non-stretch and sharpness, which affected the duration of the process. This application was documented in specific historical contexts, such as during World War II. Examining such methods provides insight into past practices and their implications.
