String Techniques

I am composing a piece based on Jewish folk melodies and came across this video:

I was just wondering if anyone knew the specific string techniques used at the beginning (roughly 0:19) and then later at 1:16. They have a specific timbre that I'd like to imitate.

Any help would be much appreciated.

The first found sounds like a fast portato and 1:16 is just....normal playing? 

It looks like she tied the strings around her waist, then started waving her arms in the air

Surely it's not just portato? Can't you hear the grating, "sawing" timbre? It's seems a very different sound to mere portato: http://www.youtube.com/watch?v=whXj4-60SR0.

If you listen to it at 1;19-1:30, there's definitely something different to normal playing - it seems more "wispy" or "airy" (a similar "sawing" sound to before). Sorry I can't describe it any better! My headphones are quite sensitive, maybe they're just picking the sound up more clearly? All I know is that it sounds different - maybe the violinist is using a different part of the bow/etc?

sounds like fretless guitar and fiddle to me. tremolo on detuned unisons or just really uneven tremolo with a weird pick. doesn't sound jewish to me.

The one at 1:16 is just sul ponticello.

As for 0:19 I'm not very sure though, sounds like a fretless guitar, like what MGladman said.

Gypsies = jews?
