It Chapter Two (Original Motion Picture Soundtrack) is the score album to the 2019 film It Chapter Two, a follow-up to It (2017). The film had Benjamin Wallfisch who scored for the first film, returning to score for the sequel. The score is "larger and more matured" than the first film, which demanded Wallfisch a 100-piece orchestra from the Hollywood Studio Symphony and 40-member voice choir performing. The album consisting of 45 tracks, were released by WaterTower Music on August 30, 2019, a week before the film's release. It was further released in double vinyl on December 6, 2019.
Development
One of the earliest discussion, Wallfisch had with Muschetti, is how to blend new themes and original themes from the first film with "more scale and ambition to reflect the scope of the film". Hence for Chapter Two, Wallfisch used a 100-piece orchestra from the Hollywood Studio Symphony and 40-member vocal choir, and in addition to several new themes, he re-recorded the themes from the first film's score with more "complex and ambitious arrangements" so as to reflect the characters development over the past 27 years, explaining "There was a lot more music required, which really allowed room for the original themes to develop and evolve in a way driven by the emotional complexity of how the Losers Club grapple with inner demons from the past and painful memories, and ultimately unite to confront their biggest fears."
Especially, for the theme of Pennywise, the film had him "vengeful and flagrant" and have a bigger presence in the film. So that "the music had to also reflect that increased darkness, whilst never losing sight of the adventure and emotion that are at the core of the movie". With The Losers Club returning as adults, Wallfisch had the opportunity to give them more emotional potency. as "they're not just kids going through the process of coming together to defeat this evil. We’re dealing with adults who have grappled with trauma and are coming together and reforming memories that have been lost." Hence, the score was much more complex, as the visual scale and storytelling and much depth in the second instalment.
Wallfisch further experimented with close-miked solo strings, where he recorded for sequences which are more visceral, as while using the close miked strings "it had much more drama than going with a hundred people playing together". The sonic choices were "counter-intuitive". He used a lot of post-processing of acoustic instruments, which he turned into electronic textures, with the sounds that originated from the orchestra. He recorded the full orchestra scoring within a single day, so as to get all kinds of "completely off-the-wall and very unusual sounds, which then formed the basis of the more experimental parts of the score". A two-week recording was held at the Barbra Streisand Scoring Stage and Warner Bros.' Eastwood Scoring Stage in Los Angeles, California, while the choir was recorded with RSVP Voices in London, which featured several professional choirs around London. He further reprised the children's choir he used in the first film. He did not re-record, but used the original recordings.
