Let me be completely honest with you… 

Music theory can be awful to learn.

Some concepts probably won’t make sense…

They’ll seem counterintuitive.

And you might feel like theory will hinder your creativity and make you a worse guitar player.

Now, all of these thoughts are valid to have.

And its normal to feel this when you’re learning any new sort of system or language...

But the fact is… 

Understanding music theory WILL make you a better musician.

Period.

Knowing music theory will allow you to play up and down the neck…

It’ll help you make sense of the dozens of different chord shapes and variations…

It will help you write better melodies, riffs, and solos…

It will help you quickly learn songs by ear.

It will help you jam with other musicians (<--- this one is super important).

Plus at least a million other ways too. 

So the way I see it, we have two options:

  1. We can ignore music theory.
  2. Or we can get our hands dirty and finally make use of it.

Because here's the real kicker...

Music theory can be awful, but it doesn't need to be. 

I know how frustrating it can feel to learn this stuff on your own, and that’s why I was inspired to create the Guitar Theory Toolbox.

This course is the sum of everything I’ve learned over the last 20 years from college classes, textbooks, online resources, private lessons, and tons of trial and error.

And while this is one the most comprehensive courses I’ve created…

(Which covers everything from notes, scales, chords, modes, triads, inversions, and a whole lot more…)

It’s designed to be extremely simple to go through.

Each video is 5-10 minutes and goes over 1 single concept.

After each section, there are challenges and quizzes to make sure you actually understand and implement this stuff right away.

This isn’t a passive course where you learn it and forget it.

This is about building a solid music foundation that will benefit you for LIFE.

“I’ve always found guitar theory confusing and overwhelming, but the way Jeff presents it finally made it click for me.”

“Even though the Toolbox goes deep, it’s still digestible. Jeff relays it in a way that makes it stick not just academically, but musically.”

Before I share more, let me introduce myself:

My name is Jeff Williams. 

I’m a musician and guitar teacher with a BA in Music from Westfield State University, with a concentration in Jazz Studies on guitar. 

Over the years, I’ve played hundreds of shows, with dozens of bands, in a handful of different genres.

Nowadays, my real passion is teaching guitar and creating YouTube videos.

Over the last 20 years, I’ve taught hundreds of students online and in-person. 

Through my experience, I've learned how to provide students with the guidance, structure, and support they need to maximize their growth and achieve their guitar goals as quickly as possible.

I’m so proud to have helped guitarists overcome their limiting beliefs, be more expressive, and have more fun.

And I’m very grateful to consistently receive positive testimonials, reviews, and video comments from all of my students. 

But it wasn’t always this way…

I used to struggle with chords, solos, jamming with others, learning new songs, and so much more.

Sometimes I felt as if I’d never improve.

I would play the guitar for hours and hours on end…

Play boring and repetitive scales until late into the evening.

And wouldn’t stop until blisters made it too painful to play.

… All without ever feeling like I was making any sort of real progress.

I’m embarrassed to say I’ve even had music teachers pull me aside and give me harsh criticism on my playing… which at the time completely crushed me.

But music was my passion and I was determined to get better

So I studied my favorite guitarists who had already achieved what I wanted to too.

I looked up to guys like Jerry Garcia, Bob Weir, David Gilmour, Trey Anastasio, Duane Allman, and others.

And eventually I realized that they weren't reinventing the wheel every single time they picked up the guitar.

Each guitarist understood the rules of the fretboard, so they could easily create any type of sound they wanted..

The special skill that these famous guitarists had is that they could communicate a sad or somber sound “on-demand”.

They didn’t need to feel a boost of inspiration or creativity to create this sound.

And after studying their songs, solos, and chords I realized that music theory was the #1 thing I needed to master to excel as a guitar player…

And so, the Guitar Theory Toolbox  was born!

This is the summary of decades of hard-earned guitar wisdom.

These are the fundamentals of the fretboard and I believe every guitarist must know them to progress to the next level.

This is crucial whether you want to write original music, play covers, or just jam and improvise - and it applies from everything to jazz to metal to rocknroll.
