Watch the Groove Nation online guitar lesson by Andrew Ford from 50 R&B Bass Grooves You MUST Know

Here we have a parliament funkadelic type synth bass line where the bass line is featured prominently in the song. It is like a song within the song propelling the groove and providing melodic and rhythmic support to the vocal melody. Very few notes are in the main bass line, mostly roots. In bar 1 over the Em7 chord we add the minor 3rd G and A the 4th that leads to our next chord Bm. We keep it simple in this bar with B, the minor 6th, G, and the root of the next chord Am which we give a little shake to the note for some character. Our next bar, bar 3 is similar to bar 1 except we end it with B and D, the 5 and b7 instead of G and A. In bar 4 we use the 4, E as the root for the Bm chord, we then hit the root B on beat 2, we do whole note slurs into both of these notes. The fill in bar 4 has a more synth bass feel to it, it has a pentatonic shape but uses the 2, B. This groove is all about the execution and attitude of the notes. You will again notice how the length of the notes plays an important part in the overall feel.
