OK guys, need some help. I've heard some fantastic basslines in folk music and it's got me really interested in actually playing it for myself.

Major problem is that I can't find any resources for it. Few tabs, practically nothing-theory wise, not even sheet music,

Now I know folk music at one point relied primarily on stuff being passed from musician to musician orally, but now there are tons of sheet music books for violin and guitar, so why no bass?
My major problem is that I suck at ear-playing...I can do it for REALLY simple basslines but otherwise I suck.

And I don't know how much you know about folk music but most of the stuff I listen to has a double bass on it at least (Seth Lakeman uses a bassist, as does the Fairport Convention and The Imagined Village).
how many folk bassists does it take to screw in a lightbulb?

1 5 1 5 1 5 1 5

for real though I have been laying around with some folk tunes lately and arpeggios and root and fifth are where its at for a good deal of it.
