 Heavily orchestrated, with strings arranged by Trevor Horn, the song describes the desire to sequester oneself from the world due to traumatic experiences it has brought about; within the context of "Fundamental", it has been observed that the song can be interpreted as a reaction to terrorism and the state of the world brought about in its aftermath.The original demo is not orchestrated, relying instead on synthetic sounds.The newly remixed radio version edits out the orchestral opening and the entire second verse, and also repeats the dramatic bridge section, adding harmonized backing vocals the second time.
