well, i guess the question is in the title - but i am always hearing people talking about how good and important they are for soloing - but how?
do you just follw a chord progression changing the arpeggio you play when the chord changes, or do you, for example, stick with a c major arpeggio if the key of the song is in c major??

also, i only tend to use one common arpeggio shape (unless i unwittingly am using others) - and that is a 5 string sweep - what other common arpeggio's are well used.

thanks for the help, its just that the term arpeggio's does confuse me, its like something everybody else seems to know except me!!!!
