Watch the Curtains online guitar lesson by Andrew Ford from 50 R&B Bass Grooves You MUST Know
This one definitely has a Curtis Mayfield flavor that you can hear in his songs such as "Superfly". It is done over a one chord vamp but uses space to create an atmosphere and then a flurry of notes at the end of the phrase to add some intensity. Here we outline the C# minor triad and then what really makes the line sing is the C# slur into the D#, the 9. That is the central focus of the line. We make it dance at the end with the 16th note pattern using G#, the 5, B, the b7, back to G#, then C#, the root, back to B and ending on G#.
