An arpeggio is just the individual accenting of each note in a chord to be heard instead of a strum of all the notes in the chords. You can arpeggiate any chord in western music. A major/minor/diminished/augmented arpeggio consist of just a first, third fifth, but there are 7th chords, etc to extend the arpeggio notes to add 7th, 9ths, whatever. Arpeggios are cool cause you can change one note in the whole pattern and it adds a whole new feel. For example of arpeggios look here http://metaltabs.com/forum/showthread.php?t=9339 Start around page 3, that where most of the sweep posts start. Most of the sweeps are arpeggios. They have patterns that span all 6 strings. The best thing to know is the CAGED theory of chord shapes, cause your arpeggio shapes follow the chord shapes. Hope this helps.
