Nocturnal Visions - Groove 16 is a video guitar lesson presented by Andrew Ford and is sourced from 30 Rock Bass Grooves for Beginners You MUST Know.
Groove 16 is a feel good groove that just puts a smile on your face, based on the Fleetwood Mac song "Dreams". It's a simple 2 chord groove that alternates between F and G playing the same rhythm up until the last bar.
Over the F chord in Bar 1, we play a familiar dotted quarter to eighth note rhythm for the first two beats, that same rhythm repeats again for beats 3 and 4, all on the root F. We keep going with that same pattern in Bar 2 for the G chord, still pumping that root note G. Simplistic and foundational, yet very cool and appropriate.
In Bar 3, we go back to the F chord and the same rhythm. In Bar 4, we start with the same rhythm for the first 2 beats of the G chord and then there is an eighth note rhythm that sets up the beginning of the 4-bar pattern. This is a very common and effective pattern used at the end of a phrase that brings the listener back to the start of a section of music. The notes used here over the G chord are the root (G), the 5 (D), back to the root, and then F# at the end, which walks us right back to F, which is the start of the groove.
