1.
A guitar technique used for playing fast arpeggios. One note per string is fretted by the left hand, while the right hand sweeps down/up on the strings in one motion. More than one string cannot ring simultaneously or it will become a chord/whatever.

The difficult part of sweep picking lies within getting your left hand to fret the notes in sync with the right hand's sweeping.

Artists that commonly use sweep picking include Yngwie Malmsteen, Paul Gilbert, and Alexi Laiho
