Watch the Warm Up Lick online guitar lesson by Jasper Mortier from 50 Blues Bass Licks You Must Know

This section is about muting the strings you’re not using, either with your left hand fingers or your right hand fingers With a pick you can do the similar thing with up-strokes and down-strokes. In the early Rock and Roll days the bass often kept on playing a single note swing bass line over the groove just like in a swing shuffle. Listen to the original Roll Over Beethoven version of Chuck Berry for instance. On Johnny Be Goode, on the other hand, Willie Dixon already starts to play some double notes. That's pretty hard on an upright, especially with that superfat sound of his! When the electric bass gaining popularity, bass players started to play double notes more and more in these kind of grooves. If you listen to the early Little Richard recordings you can hear how the straight rocker evolved from the shuffle.
