Watch the Sweet Southern Home online guitar lesson by Andrew Ford from 30 Rock Bass Grooves for Beginners You MUST Know
Groove 18 is another one of those implied eighth note grooves in the style of "Sweet Home Alabama" by Lynyrd Skynyrd. Here we have a 4-bar phrase with two chords per bar. The first two chords are D to C, both starting with two eighth notes tied to a quarter note using the root of each chord. So, the rhythm is 1 "and", then holding through beat 2, then the same thing on 3 "and", and then holding through beat 4 on C. Bar 2 starts the same way for beats 1 and 2. You'll notice in Bars 2 and 4 a chord with a slash mark. As a bass player, our main bass note is the note below the slash, in this case B in Bar 2 beat 1 and E in Bar 2 beat 4. So, on beat 1 we play the B using the eighth notes and hold through beat 2, on beats 3 and 4 we have quarter notes to break up the pattern.
In Bar 3, eighth notes again on beat 1 with the D chord, but this time we only hold it for an extra eighth note and add a low E on the "and" of beat 2 before getting back to the pattern over the F chord with two more eighth notes. In Bar 4, we have a mashup of the patterns in Bars 2 and 3, starting with the two eighths, holding for an eighth and playing another eighth on the "and" of 2 like Bar 3, all using the root G. On beats 3 and 4, we have quarters like Bar 2 using the roots B and C.
