This seems like ambient music. I have an autoharp that sounds like that one instrument on the right in the video. I was at House of Musical Tranditions in Takoma Park, Md today. About 20 years ago they had a very resonant tambura that even made a negative flanging sound when plucked. They wanted $200 for it and when I can bake later, they said they sold it. I never found another tambura that sounded like it.
