The themes go through a series of variations of orchestration, tempo and harmony to denote changes to characters and the general progression of the plot. Again, the Fellowship theme gradually comes together before appearing in a string of full heroic statements as the whole company travels and struggles. After Gandalf's demise, however, the theme appears fragmented, the harmony is changed and the instrumentation is reduced leading up to a dirge-like statement over the death of Boromir. It is gradually remade during the next two films, leading up to a grand choral statement during the assault on the Black Gate.
