Watch the 1-5-6-4 Jazz #1 online guitar lesson by Andrew Ford from Bass Groove Survival Guide

This first pattern has what we call a 2 feel. In this feel the main notes fall on beats 1 and 3 . This groove has a lot more space than a quarter note walking bass line. It is often used on verses or early in the song. In the last bar I lead back to the beginning by using the notes A and D to create a turnaround, which is a passage that leads you to the next phrase.
