Re: basic sweeping.
make sure you know what chord tones you are hitting on the sweeps too. are you on your root, 3rd, or 5th? for example, on pawel's c major shape, you have C (root), E (major 3rd), G (perfect 5th). then you can start to change that major to a minor by flatting the third. or add the 7th (B) to make it a major 7th arpeggio. and then the 9th, 11th and so on. of course, make sure you've got the basics down first, but don't get stuck on the same sweeps over and over once you're comfortable playing them. a lot of players only know minor, major and diminished and becomes kind of limiting/boring after 20 yrs of playing the same thing, like yngwie (ouch, zing!.........sorry about that hahahaha)
