Question: WHo made the music for the movies based on the 1937 novel by J. R. R. Tolkien?

Context paragraphs:
The Hobbit (film series): The Hobbit is a film series consisting of three high fantasy adventure films directed by Peter Jackson.  They are based on the 1937 novel "The Hobbit" by J. R. R. Tolkien, with large portions of the trilogy inspired by the appendices to "The Return of the King", which expand on the story told in "The Hobbit", as well as new material and characters written especially for the films.  Together they act as a prequel to Jackson's "The Lord of the Rings" film trilogy.  The films are subtitled "" (2012), "" (2013), and "" (2014).

Dagor Dagorath: The Dagor Dagorath (Sindarin for "Battle of Battles") is a fictional battle described in the legendarium of J. R. R. Tolkien.  As Tolkien's works were conceived as a fictional "forgotten history" of the world, the Dagor Dagorath represents the coming End of the World, and is often referred to as simply "The End".  As Tolkien originally wrote it, "The Silmarillion" ends with a prophecy by Mandos about the end of the world.  The published "Silmarillion" ends instead with the last paragraph of Valaquenta.  This was because Tolkien had abandoned the idea of the "second prophecy of Mandos", and the Valaquenta text, much later, contradicted it openly.  However, references to the final battle remain in the published "Silmarillion", such as a statement at the end of the Akallabêth that Ar-Pharazôn and his mortal warriors who had set foot on Aman were buried by falling hills, imprisoned in the Caves of the Forgotten until the "Last Battle and Day of Doom".  Christopher Tolkien sees the account as similar to the Nordic legend of Ragnarök and J. R. R. Tolkien also made this connection in some of his letters.

Mountain Live: The Road Goes Ever On: Mountain Live: The Road Goes Ever On is the fourth album by hard rock band Mountain.  Released following the band's first breakup in 1972, Windfall Records compiled the album using old live material.  Mountain would later reform in 1974.  The title comes from J. R. R. Tolkien's 1937 novel "The Hobbit".

Music of The Hobbit film series: The music of "The Hobbit" film series is composed and produced by Howard Shore, who scored all three "The Lord of the Rings" films, to which The Hobbit trilogy is a prequel.

Thorin Oakenshield: Thorin II Oakenshield, son of Thráin, son of Thrór, King under the Mountain is a fictional character in J. R. R. Tolkien's 1937 novel "The Hobbit".  Thorin is the leader of the Company of Dwarves who aim to reclaim the Lonely Mountain from Smaug the dragon.  He is the son of Thráin II, grandson of Thrór, and becomes King of Durin's Folk during their exile from Erebor.  Thorin's background is further elaborated in Appendix A of Tolkien's 1955 novel "The Return of the King".

Esgaroth: Esgaroth, or Lake-town, is a fictitious community of Men upon the Long Lake which appears in the 1937 novel "The Hobbit" by J. R. R. Tolkien.  Constructed entirely of wood and standing upon wooden pillars sunk into the lake-bed, the town is south of the Lonely Mountain and east of Mirkwood.  The town's prosperity is apparently built upon trade between the Men (descendants of the Edain and thus distant cousins of the Dúnedain of Gondor), Elves and Dwarves of northern Middle-earth.

Tolkien Estate: The Tolkien Estate is the legal body which manages the property of the English writer J. R. R. Tolkien, including the copyright for most of his works.  The individual copyrights have for the most part been assigned by the Estate to subsidiary entities such as the J. R. R. Tolkien Discretionary Settlement and the Tolkien charitable Trust.  The various holdings of the Tolkien family, including the Estate, have been organised under The Tolkien Company, the directors of which are Christopher Tolkien, his wife Baillie Tolkien, and J. R. R. Tolkien's grandson Michael George Tolkien.  The executors of the Estate proper are Christopher Tolkien, who is sole literary executor, and (succeeding J. R. R. Tolkien's lawyer Frank Williamson) Cathleen Blackburn of Maier Blackburn, who has also been the Estate's solicitor for many years.

Bilbo Baggins: Bilbo Baggins is the title character and protagonist of J. R. R. Tolkien's 1937 novel "The Hobbit", as well as a supporting character in "The Lord of the Rings".  In Tolkien's narrative conceit, in which all the writings of Middle-earth are translations from the fictitious volume of "The Red Book of Westmarch", Bilbo is the author of "The Hobbit" and translator of various "works from the elvish" (as mentioned in the end of "The Return of the King").

The Hobbit: An Unexpected Journey: The Hobbit: An Unexpected Journey is a 2012 epic high fantasy adventure film directed by Peter Jackson.

He is a powerful, fearsome dragon who invaded the Dwarf kingdom of Erebor 150 years prior to the events described in the novel.
