What kind of musical instruments were used in ancient barbarian tribes?
I am a member of a reenactment group in Romania, and we mostly do Roman, Dacian tribes and other barbarian tribes (allies of Dacians). Some other members including myself want to form a band, and be as historically accurate as possible. So what kind of musical instruments were used back then? I think we have the drums covered, and kind of know how they should be (with some animal skin, for example pork). But with other instruments, I'm completely lost on how it should look like, or if some sort of proto-guitar even existed. But, given the influence the Romans had in those parts of the world, can we assume that they could have used Roman instruments?
