Watch the Lesson 3: Syncopation online guitar lesson by Stu Hamm from Funk Bass for Beginners
One of the biggest things to understand about funk bass lines is that they are often syncopated like the pattern that a drummer plays. One of the things that I found helpful early on in my funk journey was looking at drum patterns in any kind of instructional charts I could find. I would try to replicate the sound of the kick drum with my thumb and the snap of the snare with a pop. We'll get to popping later in the course, but for now you want to start thinking of your thumb like a kick drum. Listen to some of your favorite records and try to imitate the kick drum pattern the drummer is playing with your thumb.
