The sound draws on the film score for Peter Jackson's The Lord of the Rings trilogy, released between 2001 and 2003 and adapted from J R R Tolkien's novels, with music composed by Howard Shore. Shore's themes for Middle-earth became some of the most recognised film music of the period and have been reused in trailers, parodies and fan edits ever since. Short excerpts circulated widely as ringtones and soundboard clips in the 2000s and 2010s, and this sixteen second swell remains popular because a few bars instantly signal adventure, fellowship and high fantasy to almost any audience.
