Piano wire, or "music wire", is a specialized type of wire made for use in piano strings but also in other applications as springs. It is made from tempered high-carbon steel, also known as spring steel, which replaced iron as the material starting in 1834. Piano wire has a very high tensile strength to cope with the heavy demands placed upon ...
Applications include piano wire (also known as [11] music wire) such as ASTM A228 (0.80–0.95% carbon), spring clamps, antennas, springs (e. g. vehicle coil springs or leaf springs), and s-tines. Spring steel is commonly used in the manufacture of swords with rounded edges for training [12] or stage combat, [13] as well as sharpened swords for collectors and live combat. Spring steel is one ...
Vibration, standing waves in a string. The fundamental and the first 5 overtones in the harmonic series. A vibration in a string is a wave. Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone.
Thread, wire, or string is wound around a grid of nails hammered into a velvet -covered wooden board. Though straight lines are formed by the string, the slightly different angles and metric positions at which strings intersect gives the appearance of Bézier curves (as in the mathematical concept of envelope of a family of straight lines).

A random wire antenna is a radio antenna consisting of a long wire suspended above the ground, whose length does not bear a particular relation to the wavelength of the radio waves used, but is typically chosen more for convenient fit between the available supports, or the length of wire at hand, rather than selecting length to be resonant on any particular frequency. The wire may be straight ...
Speaker wire is a passive electrical component described by its electrical impedance, Z. The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the imaginary component of the impedance: capacitance or inductance. The ideal speaker wire has no resistance ...
The coil is connected to a multimeter that indicates the voltage changes when the string moves. This signal is normally sent to an amplifier. A single coil pickup is a type of magnetic transducer, or pickup, for the electric guitar and the electric bass. It electromagnetically converts the vibration of the strings to an electric signal.
