Though some scenes were filmed for Dune: Part One with Gurney holding a baliset, we didn’t get any of those in the final cut. And that’s because the legendary composer Hans Zimmer recorded a lot more music for Dune than we ended up hearing. Here’s why we now know there’s a lot of music left for Part Two. If the world-building of Dune’s sonic landscape feels all-encompassing that’s because the approach to this score wasn’t just about adding a layer. Zimmer says there was an utterly “holistic” approach to recording the music for the new film, which had more to do with building the sounds from the ground-up, regardless of what was going to be used. To accomplish the unique sounds of the percussion and the voices for the Dune score, Zimmer says “We made up a lot of new instruments [with] some crazy synthesizers. There are sounds that are not of humanity. I mean, with some rhythms — there’s no way a drummer could play that.”  Zimmer also wants fans to know that the use of female vocalists in the score was something he and director Denis Villeneuve jointly decided was essential, in order to honor the source material of the novel.  As fans start to anticipate what to expect from that next cinematic Dune installment, the best way to predict that future is to look at the fascinating layers in the movie that’s out now. Although longtime spice heads have probably spotted most of the visual Easter eggs in Dune: Part One, there’s a very real chance the auditory Easter eggs may be cleverly hidden.  In the track “Stillsuits” — when Paul and Lady Jessica begin their dangerous crossing through the desert — there seems to be a slight nod to the other famous Dune score, composed by Toto and Brian Eno for the 1984 David Lynch film. Zimmer says “I’ve never seen David Lynch’s film,” and also asserts he’s never seen any version of Dune, other than the documentary Jodorowsky’s Dune. Because that failed 1970s version of Dune was planned to feature music from Pink Floyd, Zimmer incorporated a cover version of the song “Eclipse” into the first trailer for the film. Zimmer says he talked “on the phone with Roger Waters,” who advised him on how to get all the nuances of that song just right.  But that’s not all. Zimmer says there are even deeper cuts. “When I was writing the end titles, I realized there was a bassline that I’d heard before,” Zimmer reveals. “And I suddenly remembered that Klaus Schulze wrote a song called ‘Frank Herbert.’ I basically lifted the bassline from that. So, I phoned Klaus and asked him ‘could we make this a co-composition. But he was quite thrilled that something he wrote so many years ago still echoed into this century.”  So, with more Dune on the way, will we see or hear those Gurney songs, even though they’re not on the soundtrack? Zimmer makes it clear that what you don’t hear is as much a part of the world of Dune as what you do hear. Although this is no spoiler for readers of the book, because Gurney does survive well into the end of the first Dune novel, it’s conceivable that some of the songs sung by Gurney could find their way into Dune: Part Two. When the news of the sequel was announced, Zimmer jumped on Twitter saying, “Thank goodness I have some music left!” And it turns out, he’s not kidding around. In 2023, here’s hoping the baliset must flow. Dune: Part Two is expected on October 20, 2023.
