I bought a mandolin for lack of anything better to do with my money. I know nothing about strings. I'm a percussionist. I am hoping someone knows of a site with a free download that includes audio so I can tune and learn some basic beginning technique for this thing. Please help me if you can. I would love to be able to play this thing, but the only downloads I've gotten so far are only text and have no audio, so I don't even know if it's tuned right.

Thanks
