How do you sweep on guitar?

How do I properly strum a sweep arpeggio scale on guitar?

• It's driving me into madness trying to figure this out. I can tap the whole thing with my left hand fluently, but my right hand doesn't know what the hell to do. because to me it's not really a "sweep" motion, it partially is but the high e has more than one note on it in the scale. am I suposed to pick each note, having alternate pick the notes that are on the same string, or do I tap it? but if I tap it how is that "sweeping" this is really really complicated and if someone can tell me exactly how to strum a 3 string arpeggio, I would be extremely greatful.

• Answer:

  I just answered your other question, but you're asking a slightly different thing here. Once again, the real question is: does it sound different? And once again, yes it does. Picking all those notes sounds different than playing them legato. End of story. Are you "supposed" to play it a certain way? C'mon dude, be real. There are no rules to music. You play it the way that YOU think sounds best.
