The song begins with a simple piano melody before a medium-pitched droning synth is added in. A higher synth tone later joins in, playing a basic slow melody of sorts. All elements except the piano later drop out, as a lower drone provides a segue into "[[2 Ghosts I]]."
===1 Ghosts I (Extended)===
An extended version of the song appears on the feature documentary about [[Dave Navarro]]'s mother and him dealing with the aftermath of her murder (titled ''Mourning Son''). The score is by sometime NIN engineer Michael Tuller (formerly known as [[Blumpy]]).
