Watch the '61 SGLP: Intro Section online guitar lesson by John Jorgenson from Eclectic Electric: 61 SGLP
You just heard the intro to "61 SGLP", now let's break it down the first of two phrases. This is based around a B barre chord, and there are a couple of pick-ups into it, kind of like a Pete Townshend feel. You do those on the low E string, playing B on the 7th fret, and then you'll mute that string and play 8th notes. Next, bring in the two notes on the A and D string at the 9th fret, using your little finger and ring finger. You lift those off and put them back on.
You play this part three times in a row, and in the video, we'll look at this phrase slowed down. There you have the first riff!
