Physics Present in Guitar Word count: 259 There are far more physics present in the shell of a guitar than at first meet the eye. Indeed, in order for there to be any sound at all coming from the instrument, the power of physics must be invoked. First off, the strings of an electric guitar must be tightened to within the specifications of the equation: where f = the fundamental frequency of the strings when they are plucked (this is the pitch of the audible sound we hear from the instrument), L = the string length between two fixed points, T = the strings’ tension, and P = the string mass per unit length (kg/m). The tension for each string has a specific amount of tension it is required to be placed under in order to achieve the desired frequency (and thus, the desired pitch)

Unformatted text preview: Once the strings are adjusted, they are ready to be plucked. When they are, they rapidly vibrate, giving off their own frequency and disturbing any electrical fields within the range of their influence. The field most extensively affected is usually the magnetic flux created by the pickups or humbuckers (located between the neck and bridge). Pickups and humbuckers consist of tiny copper wire wrapped repeatedly around a magnet. When the magnetic field created by a pickup is disturbed, a voltage is produced and is able to be controlled by the volume reducers or the tone adjusters. The resulting signal is sent to an amplifier which can further distort, intensify, or otherwise change the sound....
