Spellsinger (1983) is a fantasy novel by American writer Alan Dean Foster.

The book follows the adventures of Jonathan Thomas Meriweather, who is transported from our world into a land of talking animals and magic.

What he gets is Jonathan Thomas Meriweather, law student, part-time would-be rock guitarist and janitor, who finds that with the use of a unique instrument called a duar, he can perform magic by playing and choosing from his well-worn repertoire of rock songs.

Jon-Tom, as he is called in Clothahump's world, quickly discovers that while he might be able to use magic with his music making, the results are often unpredictable and usually humorous.

Ever searching for a way to get back to Earth, Jon-Tom takes up the battle to save this world.
