Monochord

A monochord is a simple musical instrument consisting of a single, long string stretched over a resonant box or soundboard. When the string is plucked or bowed, it produces a musical note. By adjusting the length of the vibrating part of the string with a movable bridge, players can change the pitch. Historically, it has been used to study the relationship between string length and pitch, as well as to demonstrate the physics of sound and harmony. The monochord is a valuable tool in both musical and scientific contexts for exploring fundamental principles of acoustics.
