At a new website, The Music of the Lord of the Rings Films, John Jennette has converted the information in the Annotated Scores of the LOTR films (one for each film) from pdf to html format. The Annotated Scores, written by Doug Adams, are companion pieces to the three sets of Complete Recordings and were offered as a free download at the Reprise LOTR soundtrack site. The analysis, though written for the Complete Recordings, can be applied to the movie as well and John also has sound clips available for reference.
Thanks to Doug Adams for pointing this site out to us.
