...how can i sweep more then one note on a single string??

Legato...inside of picking the notes "inbetween" the string, hammer on/pull off to them...This allows your right hand to continue in the same motion whilst playing more than one note on a string......
Hopefully that made some sense...feel free to ask if there's something I've not explained well. Have fun, see y'all later!
