[Description: A grand, tragic orchestral piece evoking the Ice Age. Low strings and sub-bass drones establish a frozen landscape. A sparse, mournful melody in high strings emerges, like the call of migrating mammoths. The choir enters with wordless, solemn tones, representing the human struggle against the elements. Percussion punctuates the hardships, building to a powerful, bleak climax before fading into a desolate, wind-swept silence.]
弦乐采用低音区的持续长音与高音区的破碎旋律，形成广阔与脆弱的对比。
合唱部分用慢速的元音（如“啊”），从极弱渐强，营造史诗感。
低频用正弦波或低音提琴持续铺垫，增加压迫感。
定音鼓和低音鼓在关键处重击，象征灾难与挣扎。
混响采用巨大空间（冰原或山谷）卷积混响，衰减时间3秒以上。
结尾可让所有元素渐弱，仅留风声低频嗡鸣。
