"My initial instinctive approach to the score, which our director, Baltasar Kormákur, liked and encouraged me to follow, was to have a calling voice, a distant siren call," explained Marianelli. "It is at the same time a voice that represents the ancient goddess-like mountain, but also a luring and irresistible calling to one's own destiny."
"The opposite point of the musical compass is the 'conquering' attitude of the mountaineers, a kind of macho, go-getting approach to nature," Marianelli continued, "which is reflected in a much more propulsive, percussive and energetic musical idiom."
Marianelli's musical "siren call" was performed by singer Melanie Pappenheim. He concluded: "The same tune that I wrote for Melanie was also played by two wonderful string players in many variationsCaroline Dale and David La Page, with whom I also have worked on several other movies," he said. "There were also moments where I tried to evoke a primal, raw power, and I tried to build a sense of surging pressure with the blasting brass instruments."
