Watch the My Pearl online guitar lesson by Andrew Ford from 50 R&B Bass Grooves You MUST Know
Check out this 1 to 4 bass line ala My Girl, because of the simplicity of the line we need to really commit to playing it with a strong sense of timing and big tone. We are just using the root or 1, which is C, to the 5th which is G in bar 1. Don't go through the motions in playing this simple phrase, there are subtleties like cutting off the 3rd eighth note right before the & of beat 2 that make a big difference in this groove. The last note in bar 1 should create forward motion by playing it slightly staccato. Bar 2 uses a 1, 2, 3, 5 pattern where we play a muted F to set up the last phrase on beat 4, a 3-5-3 pattern that is swung.
