Watch the Picked Arpeggios online guitar lesson by Rich Maloof from Guitar 201: Breakthroughs
Let’s gain acumen with the pick so that you can do more than strum with your right hand. The key to getting picked arpeggios together is to work on control and timing. Each individual note should be in time, with really no difference between the down-stroked and up-stroked notes.
If you’ll forgive the fogeyism of the song choice, this one offers a great way to start on picked arpeggios using upstrokes and downstrokes. Play it till you can't stand this song anymore, if that didn't already happen to you around 1973.
