The music is very much in panicking style, giving chills the moment it starts playing, sounding quite similar to music for classic horror movies.
The soundtrack consists of high strings droning in the background while more strings and possibly brass play sharp notes. It has a repetitive violin screech too. It gets steadily faster, then finishes with a bass drum.
It plays few moments later when Henry uses the cable car from the cavern after one of the old ropes began to snap apart.
The entire track is heard playing in Chapter 4's launch trailer.
