Watch the Sure online guitar lesson by Stu Hamm from Essentials: Rock Bass Grooves

Another bassline that'll appear on anyone's list of "Greatest Rock Basslines" will be "Roundabout" as played by Chris Squire of Yes. In this track, I've attempted to capture the spirit of Chris' unique bass style. At first you'll play a unison line, meaning a phrase that is played together by all members of the band. You'll have to listen closely to how the drums and guitar are playing it to play it and blend in. The main groove contains a stream of sixteenth notes that need to be played with precision, accuracy, and a rocking feel. Pay close attention to the hammer-ons from G to A in the phrase at the end of the line, coming back to the unison line.
