Shore began his work on the music early during the production of "" in late 2000 and recorded the first pieces of music (the Moria sequence) in spring of 2001 to a 40-minute teaser of the film, as the film was still being shot. The scored section also included a version of the Breaking of the Fellowship sequence, with an extended tin whistle solo, and a montage of footage from the following two films. The rest of the score was recorded in London during the editing of the film in post production, and took over 180 hours to record. Shore would later return to the finished film, recording additional music and revised takes for the extended DVD version in March 2002.
