Let’s talk music theory—not the boring kind, but the kind that actually helps you create better bass lines right now.
In this post, I’m going to show you a simple music theory trick that forms the foundation of 80% of modern music—and how to take that knowledge and turn it into real-world bass playing.
This is part of a bigger system I call the Applied Music Theory System, and trust me, it’s all about getting results fast without needing a degree in jazz composition.
🎯 The Trick? The Major Scale Formula
You’ve probably seen this before:
W W H W W W H
(Whole, Whole, Half, Whole, Whole, Whole, Half)
That’s the formula for building a major scale—and it’s the backbone of so many grooves across funk, pop, soul, and rock.
In this week’s video, I walk you through this formula using the A Major Scale and then show you how to apply it straight away using triads—3-note shapes that define the sound of chords.
🎵 From Theory to Groove (In 3 Levels)
This isn’t about learning theory in isolation.
You’ll play:
- Quarter notes (Level 1)
- Eighth notes (Level 2)
- And for the adventurous… 16th notes (Level 3)
We put it all over a 1–4–5–4 chord progression—something you’ll hear in literally thousands of songs.
I’ve put together a free PDF so you can follow along with everything inside the lesson.
(It’s great for practicing the exercises and keeping handy on your music stand.)
