How to Build a Motown-Inspired Bass Line from a Simple Chord Progression

The bass lines that make me think of Motown, Memphis, and Muscle Shoals often start with a simple idea played with a strong feel. In this lesson, I’m building a late ’60s soul and R&B groove from a chord progression, then using a few notes and a repeating rhythm to bring it to life.

I’m playing a Fender Vintera III Late ’60s Precision Bass today because it feels right for this music. We’ll draw inspiration from players like James Jamerson, Duck Dunn, and David Hood as we work through the groove.

Start with the Chord Progression

We’re in the key of G, playing an eight-bar phrase:

• G for two bars
• E minor for two bars
• C for one bar
• D for one bar
• G for two bars

That gives us the I, vi, IV, and V chords. G, C, and D are major; E minor is our minor chord. Paying attention to that difference helps us choose notes that fit as the progression moves.

Build the Major-Chord Bass Pattern

A major triad gives us the root, third, and fifth, but for this groove I’m using the root, fifth, and sixth instead. That sound connects to blues and early rock and roll bass lines, and it gives us a useful starting point for this style of soul and R&B.

Over G, those notes are G, D, and E. I’m starting on a higher G and using the lower fifth and sixth beneath it. The notes are simple; the fun is deciding what order to play them in and finding a rhythm that feels good.

Try repeating a short phrase that returns to the root. You can use your index and middle fingers to work through it. As you play, pay attention to where the phrase lands at the beginning of each bar.

Leave Space Around Beats One and Two

Before adding more notes, play through the progression while focusing on beats one and two of each bar. That establishes the framework of the groove and lets you hear how much space is available afterward.

Once that feels comfortable, bring in the root, fifth, and sixth pattern. Repeating an idea across the chords gives the bass line a sense of continuity, while the space leaves you room to shape the phrase.

Adjust the Pattern for E Minor

When we reach E minor, I change one ingredient. Instead of using the sixth as I do over a major chord, I use the minor seventh.

Our notes over E minor are E for the root, B for the lower fifth, and D for the minor seventh. I can keep the same rhythmic idea from the G bars while changing that note to suit the minor chord.

From there, the progression moves to C and D for one bar each before returning to G for two bars. Play the whole eight-bar phrase and listen to how the repeated pattern carries you through those changes.

Once you have the groove in place, try a dead note or a fill if it feels right. You don’t need much to get started. A few well-chosen notes, a rhythm you can repeat, and attention to the space between phrases can take you a long way.

Happy practicing, everybody. Keep it groovy.
