Alexander Courage, John Neufeld, Conrad Pope, Aimee Vereecke and Dennis Dreith served as orchestrators.

A 20th anniversary edition of the soundtrack was released by Geffen Records on April 9, 2013, featuring additional unreleased music.

A John Williams collection edition, joint with the soundtrack to The Lost World, was released by La-La Land Records on November 29, 2016, remastered and featuring more additional unreleased music.

Williams began writing the Jurassic Park score at the end of February 1993, and it was conducted a month later; because Williams sustained a back injury during the scoring sessions, several cues were conducted by Artie Kane[3] (Kane is uncredited in the film, but receives special thanks in the 1993 soundtrack album's credits and is listed as a conductor in the La-La Land Records set).

The score was orchestrated by Alexander Courage, John Neufeld, Conrad Pope, Aimee Vereecke and Dennis Dreith.

[7] As with another Spielberg film he scored, Close Encounters of the Third Kind, Williams felt he needed to write, "pieces that would convey a sense of 'awe' and fascination", given that the movie dealt with the, "overwhelming happiness and excitement", that would emerge from seeing live dinosaurs.

Instead, Williams gave Spielberg demo tapes with piano versions of the main themes prior to his travel, and the director would listen to them daily on the way to the sets.

Some cues, such as "Dennis Steals the Embryos", feature them prominently, but many of the synth passages are mixed much more quietly, often doubling the woodwinds or helping flesh out the lower harmonies.

Variations of "Theme from Jurassic Park" and "Journey to the Island" are used for the score's quieter, more tender moments, typically with woodwinds, horns, or keyboards.

[12] The score, along with that of The Lost World: Jurassic Park, was remastered and re-released by La-La Land Records on November 29, 2016.
