Watch the 70's Dance Groove online guitar lesson by TrueFire from Play Bass Guitar 6: Groove Lexicon
70's Dance Groove - Bass Line #15 is a video guitar lesson presented by David Santos and is sourced from 50 Bass Grooves You MUST Know.
This is a one chord vamp on a G7. The bass line is a two measure phrase. The key is to use clever ways of embellishing the line in a funky way that is sometimes difficult to analyze or describe. Slight changes here and there realized as a note, a touch, a little direction change, a fill, a trill, a different low note, but nothing too obtrusive. Dig into the line!
