Watch the Pop-Reggae Hybrids online guitar lesson by Andrew Ford from Focus On: Reggae Bass
Here is a groove in the style of UB40 or other bands that blended synth driven pop with reggae. The focus here is on being melodic while locking in to the drums. This is an example of a bass hook, making the bass line as singable as any hook or chorus in a song. This is a simple 1-4 progression in Ab. We start on the 5 which is Eb and slur into the 6, F. We continue this set of 8 sixteenth notes motif by playing over the beat, we play right through beat 2 with 4 Ab's which is the root and end the sixteenth run with the 6 and 5 again before landing on the root on beat 3 of the new chord Db. The next bar is the same up until we get to the Db chord change. There, instead of finishing the motif on the root like bar 1, we finish with a triad based figure in Db using the 5, Ab, the major 3rd, F, and then twice on the root, Db.
