 Composer John Williams began scoring the film at the end of February , and it was recorded a month later . John Neufeld and Alexander Courage provided the score 's orchestrations . Similar to 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 it dealt with the " overwhelming happiness and excitement " that would emerge from seeing live dinosaurs . In turn more suspenseful scenes such as the Tyrannosaurus attack earned frightening themes . The first soundtrack album was released on May 25 , 1993 . For the 20th anniversary of the release of the film , a new soundtrack was issued for digital download on April 9 , 2013 including four bonus tracks personally selected by Williams .
