Interrupted Music is a 2005 book of literary analysis by Verlyn Flieger of J. R. R. Tolkien's legendarium, the mass of documents summarized in The Silmarillion.

The philologist and fantasy author J. R. R. Tolkien spent much of his life constructing his legendarium, a body of writings on his fictional world of Middle-earth.

[12] The influences she identifies include the Celtic otherworld, stories of "sunken or engulfed lands" like Tolkien's Númenor, and the immram tradition of wandering sea-voyages.

David Bratman, in Mythlore, describes Interrupted Music as "a full-length meditation on the framing of the series" of 12 volumes of The History of Middle-earth.

[9] Thomas Fornet-Ponse, in VII, writes that the tradition chapter shows how "Tolkien depicts his work like a true mythology with different layering, multiple narrators, overlapping texts and variant versions.

"[17] Nagy considers the chapter on the tradition of the legendarium "an admirable synthesis", and "the most important part of the book", and that Tolkien's self-referentiality is "very effectively reflected on".
