|-17---17p14---17p14------17p14-------17p14---------|          Try practicing slowly with one note at a time untill 
|--------------------15---------15---------15-------|          u can play the whole downward part of the sweep.

|-17p14----------17p14-------------|        Just start practicing the downward sweep first until you are 
|-------15-------------15----------|        comfortable with it and try not to let each note run into each other.
|----------14-------------14-------|        The speed will come naturally as you practice.(Downward sweeps are easier
|----------------------------------|        than upward sweeps).

|---------------------------------------------|          and adjust your style to it and play it slowly and

|-17p12----------------------------12--|    Here is a five string sweep and beleive it or not it 
|-------13----------------------13-----|    is actually easier to do than a 3 string sweep.
|----------14----------------14--------|    Marked above the tab line is the way i prefer to
|-------------14----------14-----------|    use my fingers to fret the notes. I think this sweep 
|----------------15-12p15--------------|    is harder to do at slow speed.
