Playing but Not Progressing?
End Your Guitar Plateau Now.

You've put in the time. Maybe decades. You can play—but when someone says "let's jam in D," you freeze. When you try to solo beyond your comfort zone, you're guessing. And deep down, you know other players can hear it.

That constant "I should know this by now" feeling? It's eating at you.

Here's the thing: It's not that you haven't worked hard. It's that no one ever showed you how all the pieces fit together.

You learned chords as shapes. Scales as patterns. But no one explained:

You've been building a house without a blueprint—and wondering why it feels so shaky.

I've guided 15,000+ self-taught guitarists through this exact breakthrough. Most of them were long-time players—some with 20, 30, even 40+ years of experience—who finally understood the music they'd been playing all along.

Guitar Theory Unlocked is the blueprint. The roadmap. The missing piece that connects everything you already know into a system that actually makes sense.

The Three Big Struggles Guitarists Face
(and Why GTU Solves Them)

1. "I know chords, but I don't understand WHY they work together."

The pain: You've memorized G-D-Em-C... but why do those chords belong together? What key are you in? Why does Am work here but A major sounds wrong? When someone asks you to play the same song in a different key, you're stuck—because you memorized shapes, not the logic behind them.

The consequence: You can play songs exactly as written, but you can't transpose them, understand them, or make them your own. You're trapped in other people's arrangements.

How GTU solves it: GTU teaches you the Nashville Number System (I-IV-V) and shows you how to build chords from the major scale. Once you understand this, you'll know which chords fit in ANY key—and you'll be able to transpose any song in seconds.

2. "I can't transpose songs or figure them out by ear"

The pain: When a song's too high for your voice, you're stuck. You can't transpose it because you don't know which chords to substitute. When you hear a song on the radio, you can't identify the progression—you're dependent on tabs or chord charts for everything. You need someone else to figure out the music for you.

The consequence: You'll never develop your musical ear. You'll always be stuck playing in the "easy" keys (G, C, D, E). When you want to play with singers or other musicians, you can't adapt on the fly—you need everything written out in advance. And forget about spontaneous jam sessions where someone just starts playing. You're always a step behind, scrambling to find a chart on your phone.

How GTU solves it: GTU teaches you how to identify common progressions by ear (I-V-vi-IV, I-IV-V, etc), use the Nashville Number System to transpose instantly, and recognize what key a song is in just by listening. You'll stop relying on tabs and start trusting your own understanding. Once you get this, you'll be able to play along with ANY song after hearing it once or twice.

3. "I feel like a fraud when musicians talk theory"

The pain: Someone says "let's do a I-IV-V in A" and you nod along... then quietly panic. They mention "the relative minor" or "borrow the IV chord" and you have NO idea what they mean. You've been playing for decades, but you can't participate in basic musical conversations. It's embarrassing—and it makes you feel like you don't really know your instrument.

The consequence: You avoid jam sessions. You stick to playing alone in your room. You miss out on musical opportunities because you're afraid of being exposed as someone who "doesn't know theory." Other players assume you're not serious about music—when the truth is, you just never had anyone explain this stuff in a way that made sense. And that feeling of being a musical outsider, even after years of playing? It never goes away until you learn this.

How GTU solves it: GTU translates music theory into plain English and shows you how it applies to real music—not just academic exercises. You'll learn what "the IV chord" actually means, how to find the relative minor in 3 seconds, and how to speak the language of music with confidence. No more nodding and pretending. No more feeling left out. You'll finally be part of the conversation—and you'll wonder why no one explained it this clearly before.

Here's What Changes When Theory Finally Clicks

Scenario 1: The Jam Session

Scenario 2: The Singer Who Needs a Different Key

Scenario 3: The Conversation You Can Finally Join

What You'll Learn (And Why It Changes Everything)

The course includes 6.5 hours of focused, step-by-step, bite-sized video lessons—designed to be practical, digestible, and immediately applicable.

Module 1: Music Fundamentals

What you'll learn: The musical alphabet (A-G with sharps and flats), how whole steps and half steps work, and how notes are organized on the guitar fretboard.

Why it matters: You'll stop guessing where notes are and start understanding the logic behind the fretboard. When someone says "play an F# in the bass," you'll know exactly where to find it—on any string. You'll also understand why there's no "B#" or "E#," which demystifies chord construction and scale patterns. This is the foundation that makes everything else click.

Module 2: Keys, Scales and the Number System

What you'll learn: How major scales are built, why certain chords naturally fit together in a key, and how the number system (I-IV-V, etc.) works.

Why it matters: You'll finally understand why G-D-Em-C "just sounds right" together—they're the I-V-vi-IV in the key of G. When you hear a song, you'll start recognizing common progressions by ear instead of scrambling for tabs. You'll know which chords fit in any key, so you can write your own progressions or add chords to songs without trial-and-error.

Quick example: Right now, if someone plays a song and you want to join in, you're probably thinking "where's the chart?" After this module, you'll think "okay, that's a I-V-vi-IV... so if they're in C, that's C-G-Am-F. I know where those are." That's the difference between guessing and knowing. This is where music stops being random shapes and starts making logical sense.

Module 3: Chords

What you'll learn: How chords are built from intervals and patterns (not just memorized shapes). You'll learn triads, inversions, the number system for chords, and how to move chord shapes across the neck with confidence.

Why it matters: Chords stop being mysterious shapes and become something you actually understand. You'll know why a C major chord is made of C-E-G, and how to find different voicings of the same chord all over the fretboard. This means more creative options when playing, less reliance on the same old open chords, and the ability to play richer, more interesting rhythm parts.

Module 4: Relative Major & Minor

What you'll learn: How every major scale has a related minor scale, and how to switch between them in real time.

Why it matters: You'll understand mood shifts in progressions and solos. When a song goes from bright to dark, you'll know why—and you'll be able to do it yourself. This connects directly to your playing, helping you navigate songs that move between major and minor, and giving you more emotional range in your own music.

Module 5: Useful Tools

What you'll learn: Practical applications—transposing songs, using a capo to change keys, navigating the fretboard with anchor notes, and identifying common chord progressions quickly.

Why it matters: This is where theory becomes a superpower.

When a song's too high for your voice, you'll transpose it in seconds. When jamming, you'll recognize progressions instantly and jump in confidently. These are the skills that make you feel like you finally "get" music—and they translate directly to playing and songwriting.

Module 6: Working With Progressions

What you'll learn: The most common progressions in modern music, how to write chord charts, how to find the key of a song (by ear or by chord shape), and how to transpose confidently to suit your voice.

Why it matters: Theory starts to sound like music. You'll explore real progressions used in hit songs, learn how to write your own from scratch, and develop the ear to identify what's happening in any song you hear. There's even a songwriting section where you build a progression from scratch—so you're not just learning about theory, you're using it creatively.

Bonus: Your Theory Study Buddy

Learning theory is one thing. Putting it into practice is where the real magic happens.

The Theory Study Buddy is a 1-hour guided practice session designed to help you review key concepts, reinforce your understanding, and actually use what you've learned in a hands-on way.

Whether you're working through scales, chords, or progressions, this bonus session acts like a friendly coach sitting beside you—keeping you on track, motivated, and moving forward.

Included at no extra cost in both the Basic and Deluxe packages.

Will This Work For You?

You might be wondering if this is right for you—especially if you've tried (and quit) theory courses before. Here are the questions most students have:

"I've tried learning theory before and got lost."
