Watch the 8th Note Displacement Combos: 3 online guitar lesson by Jon Finn from Rhythm Lab: Rock & Funk
Each example is 4 measures long and repeated. In each example, the 1st and 3rd measures always accent the 3rd eighth note, while the 2nd and 4th measures "displace" the accent. In example 22, measures 2 and 4 accent the 1st eighth note, while example 23 accents the 2nd eighth note.
Next, Example 24 accents the 4th eighth note (skipping the 3rd eighth note which is next in the sequence because it's redundant). Each subsequent example accents the next eighth note until all the possibilities are exhausted. Note that the chord D5 is played for the first two measures, while Bb5 is played for the 3rd measure, then C5 for the 4th measure.
