Watch the True Groove online guitar lesson by TrueFire from Play Bass Guitar 4: Groove Vocabulary
True Groove - Groove 21 is a video guitar lesson presented by Andrew Ford and is sourced from 50 R&B Bass Grooves You MUST Know.
The feel here is quasi synth bass like in the style of the Earth Wind and Fire bass line for Let's Groove. It is a 2 bar phrase where we drive the 3 quarter notes in bar 1 giving them their full value to create the synth feel, resting on beat 4. Then in bar 2 we have our 8th note walk up over the F#m7 chord leading to the B7. These notes are F#, A, Bb, our leading tone and then B the 1st note of our new chord. We end this lick with a slide up to B at the 9th fret of the D string. We also give this note a little shake for extra vibe. Mastering these type of slides can make your basslines more dynamic.
