Watch the Jumpin' Jacks online guitar lesson by Andrew Ford from 30 Rock Bass Grooves for Beginners You MUST Know
Groove 7 is based on the bassline in "Jumping Jack Flash" by the Rolling Stones. This is a nice medium tempo groove with a strong quarter note driven bassline that is pretty funky but rocks. It's a 4 chord, 4-bar groove starting on D.
The first bar starts with a couple of quarter notes on D, then we hold that second D past beat 3 and have syncopated rhythm using eighth notes on the up beats, which are the "ands" when we are counting. The C# and G# are on the "ands" of 3 and 4 respectively. The next bar changes to an A chord where we again reiterate that strong 1, 2 rhythm with the quarter notes. We follow that with another upbeat type of rhythm even though all 3 notes are not on up beats. They fall on the "and", 4, and with the notes C#, D, and D#. This last D# transitions nicely to the E chord in the next bar. On this chord, we give the bassline and the song some space, nice use of what we call dynamics, ways to make things come alive, not be so static. So, we have the root E playing a half note, in the same bar we follow that with a couple of quarter notes, the first one repeating the root and the second using that b7 which can be used with a major chord like E to give it a bluesy sound. The last bar has our old reliable dotted quarter eighth rhythm where the eighth is tied to a quarter note so we hold the note for that duration. Then, we finish with another quarter note all on the root B.
