Frankenstein; or, The Modern Prometheus is a novel written by Mary Shelley about an experiment that produces a monster. Shelley started writing the story when she was eighteen, and the novel was published when she was twenty-one. The first edition was published anonymously in London in 1818. Shelley's name appears on the second edition, published in France in 1823.
Shelley had travelled the region in which the story takes place, and the topics of galvanism and other similar occult ideas were themes of conversation among her companions, particularly her future husband, Percy. The actual storyline was taken from a dream. Mary Shelley was talking with him and two other writer-colleagues, Lord Byron, and John Polidori, and they decided they would have a competition to see who could write the best horror story. After thinking for weeks about what her possible storyline could be, Shelley dreamt about a scientist who created life and was horrified by what he had made. Then Frankenstein was written.
Frankenstein is infused with some elements of the Gothic novel and the Romantic movement and is also considered to be one of the earliest examples of science fiction. Brian Aldiss has argued that it should be considered the first true science fiction story, because unlike in previous stories with fantastical elements resembling those of later science fiction, the central character "makes a deliberate decision" and "turns to modern experiments in the laboratory" to achieve fantastic results. The story is partially based on Giovanni Aldini's electrical experiments on dead and (sometimes) living animals and was also a warning against the expansion of modern humans in the Industrial Revolution, alluded to in its subtitle, The Modern Prometheus. It has had a considerable influence across literature and popular culture and spawned a complete genre of horror stories and films.

It should be added that at no time was it suggested that Frankenstein's monster played the electric guitar (not least because the instrument post dated him by decades). However...I reckon he would have done given the chance :)
