Bars 1 through 5 feature some of the trickiest picking patterns for those of us inexperienced with the art of economy picking. We float through segments of arpeggios as well as some scale-oriented passages.
Remember: The rhythm never changes and EVERY note is picked. This is the tricky part: not blurring notes together simply due to a change in the number of notes executed on each string. The notes in the sweep arpeggios occupy the same amount of "space" as any other.
