They have a TON of instruments from all over the world here -- and it's overwhelming at times. Each display featured a particular country and had examples of instruments from that country with a short description. Then, there was a video monitor for each country which played a loop of a few short clips of people playing the instruments. My one complaint was that I didn't feel like some of it was put in enough of a cultural context, since the descriptions were rather short.
Very impressive collection.
