How does a 12-string guitar work and produce its unique sound?

A 12-string guitar works by having six pairs of strings, with each pair tuned to the same note but one octave apart. When played, these paired strings vibrate together, creating a fuller and richer sound compared to a traditional 6-string guitar. This unique sound is achieved by the doubling of each note, creating a chorus-like effect that is characteristic of the 12-string guitar.
