Sympathetic Vibrations
There is a typical classroom physics demonstration where one tuning fork is set into motion and an identical tuning
fork, if placed closed enough, will also be set vibrating, though with smaller amplitude. The same effect occurs when
tuning a guitar. One string is plucked and another, whose length is shortened by holding it down some distance from
the neck of the guitar, will also be set into vibration. When this condition is met, both strings are vibrating with the
