As a selection from Giuseppe Verdi's Nabucco is played in several different sequences in the film, Argento tasked Emerson with including the piece in his soundtrack.

Emerson re-orchestrated "Va, pensiero..." in five-four time to mimic a "fast and bumpy" taxi ride through Rome.

[3] When Argento reviewed Emerson's progress he did not initially recognize the remix, but was later pleased to discover it was used for Sara's taxi ride.

Time Out's Scott Meek noted that "Argento's own over-the-top score [for Suspiria] has been replaced by religioso thunderings from the keyboards of Keith Emerson.

"[6] While Guido Henkel of the DVD Review website wrote that Emerson's score was "a beautiful and impressive piece", he felt that "[t]he music is poorly spotted and too often cues are placed where they shouldn't be, or placed so that they actually break tension rather than help building it.
