This is the first lesson on "Sweep Arpeggios"...we are just getting the basic technique down and learning a few basic arpeggio shapes.
An "Arpeggio" is just a chord played one note at a time instead of all together in a strum. When we "sweep" the arpeggio we are playing the chord with one note per string and we're moving the pick the same direction through each string until we run out of strings in the pattern and then we "sweep" the other direction....
