I am creating a tundra-nomad inspired culture, but I'm having trouble figuring out how to design instruments that will seem believable for these people and also be unique when compared to the real world. The nomads are primarily herders who control large, yak-like beasts for milk, meat, and wool, and make their money from trading these materials in markets. One of the ways they pass the time is through playing music. I have thought about making a pipe-like instrument made from an animal tusk and stones, but I still have no idea how it would sound or be played on. Any help or suggestions would be great!
