Watch the J Five online guitar lesson by TrueFire from Play Bass Guitar 6: Groove Lexicon
J Five - Groove 2 is a video guitar lesson presented by Andrew Ford and is sourced from 50 R&B Bass Grooves You MUST Know.
The Jackson 5 were a big part of the Motown sound and R&B music and this groove based on one of their biggest hits is very catchy. It is basically built on the descending A major scale except that before it resolves to the root it goes to the 5, E then back to the root to start the next phrase. A couple things of particular interest are the short and long note phrases in bar 1, for example the G# is long then the F# and E phrase is more staccato then the D and C# are longer, and secondly the 16th note phrase starting on beat 3 of the 2nd bar has a nice pattern that walks up from B diatonically in the key of A to C#, then D, chromatically up to D# then E before going down to open E then continuing up the scale to F#, G#, and back to A to start the pattern over. This pattern seems to be easier to finger using all four fingers in the left hand for this phrase at least. You need to quickly slide up the second note in bar 1, E to keep the transition smooth in starting the phrase over.
