All of these themes were compiled into a menu by musicologist Doug Adams, who worked with Shore on the documentation of the score. Doug identified about 90 motifs (some very brief, scarcely used and/or only subtly differentiated from others) in the three Complete Recordings, by far the largest catalogue of themes for a theatrical work. Furthermore, in creating The Hobbit scores Shore would not only add another 62 themes or more, but actually went on to reuse some isolated musical gestures from the Lord of the Rings scores, turning them into leitmotifs after-the-fact, adding up to over 100 leitmotifs used in the Lord of the Rings trilogy alone, and 160 when combined with motifs of The Hobbit. There are also leitmotifs which Shore only used in alternate forms of pieces from the soundtracks, and even several variations and diegetic pieces that can be added to this count, as well.
