A complete step-by-step course to help you master arpeggios in any key, across the entire guitar neck.


😖 You’ve played for years… but when it’s time to solo, you feel boxed in.
You run up and down scales and hope something lands.
🧠 You know some theory.
Pentatonics. CAGED. A few solid concepts.
But you’re still not connecting the dots across the neck.
🔺 You’ve tried arpeggios…
…but you only know a few shapes, and they feel clunky, stiff, or disconnected from real music.
🎯 You can solo… kind of.
Some moments work. Most feel hit or miss.
And it rarely sounds fluid, musical, or intentional.
📚 You’ve put in the effort.
Courses. YouTube videos. PDFs.
Yet you still don’t feel confident or free when improvising.
🎸 You want to sound like you.
Not like a scale exercise or a string of random licks.
⏱️ You’re done noodling.
You want real, musical progress and you want it fast.
✅ If any of that hit home, here’s the good news:
You’re not as far off as you think.
🎶 Playing Confident, Musical Solos Is Easier Than You Think
🚫 The problem isn’t you.
Most guitarists are given scattered bits of information and expected to somehow connect everything on their own. That’s why you stay stuck.
🔁 What usually happens instead:
You run scale or arpeggio drills with no real musical context.
Then when it’s time to play over chord changes, you freeze…
or noodle around hoping something sounds right.
✨ Mastering Diagonal Arpeggios is different.
It’s built around one simple idea:
👉 The fastest way to sound musical is to practice arpeggios in a way that lets you make music immediately.
Inside the Course, You’ll Learn:
🎯 Every Arpeggio You Need
From triads to seventh chords, all the way to extensions like 9ths, 11ths, and 13ths — mapped across the entire fretboard. You’ll see exactly how to play them in any key, anywhere on the neck.
🙌 Musical Application from Day One
No endless, mechanical drills. You’ll use science-backed practice methods and musical exercises that make the arpeggios stick, so you can recall and use them naturally in any situation.
🕒 Real-World Improvisation Skills
Apply diagonal arpeggios over real progressions. Learn how to weave them into your phrasing so your solos sound deliberate, expressive, and connected to the harmony — not random scale runs.
You’ll even see exactly how I practice these arpeggios in my own sessions, so you can model and adapt the process for your own playing.
Once These Pieces Click, Everything Changes:
✅ You stop second-guessing your note choices.
✅ You can target chord tones in any key, anywhere on the neck.
✅ Your solos feel more melodic and connected to the music.
✅ Practice becomes inspiring because it sounds like music.
And the best part?
You don’t need 90 minutes a day. The system is designed so you can make real progress in 20–30 minutes — even with a busy schedule.
If you’re ready to leave scale noodling behind and start building solos that mean something, Mastering Diagonal Arpeggios will get you there.



I’ve been playing guitar since I was 13. Like a lot of people, I started with tabs and taught myself enough to get by. I could play songs, but I always felt like something was missing. I didn’t sound connected. I didn’t sound like myself.
I looked for teachers, but growing up in Charlotte, I couldn’t find anyone who could really help. Some didn’t seem interested. Others just didn’t know how to explain things in a way that made sense. So I kept pushing forward on my own.
Eventually I found some classical teachers after moving to Winston-Salem, which opened some doors for me. But I still wasn’t learning how to solo or express myself on the instrument. That led to years of chasing answers. I went on to study classical and jazz guitar in college, took lessons with over 100 different teachers, and attended masterclasses with some of the best in the world. I’ve now taught over 25,000 guitar lessons since 2007.
But even with all of that, what shaped me the most was learning alongside my students. Seeing what worked and what didn’t, and finding better ways to help people break through the same walls I used to hit myself.
If you’re someone who’s been playing for a while but still feels stuck... someone who wants to sound more musical, more expressive, more like themselves when they play... then you’re exactly the kind of player I built my approach for.
Because I’ve been there. And I’d be glad to help you move forward.
After teaching over 25,000 guitar lessons since 2007, I kept hearing the same struggles.
You’ve been playing for a while. You know some scales. Maybe you’ve even taken a few courses. But when it’s time to solo, you still feel stuck. You can find a few arpeggio shapes, but they feel random, disconnected, and hard to apply musically. You’re not sure how to target chord tones in real time. Your solos drift into scale runs, the phrasing feels clunky, and the whole thing ends up sounding like “filler” notes instead of melodic, confident playing.
I built Mastering Diagonal Arpeggios to fix that.
This is a course for guitarists who want to make their solos sound deliberate and connected — not like aimless scale patterns. It’s built specifically for intermediate players, mostly electric, who are tired of practicing shapes without hearing the results in their actual music.
You’ll learn how to solo anywhere on the neck, land on the right notes at the right time, and make your playing sound like real music — even when you’re improvising on the spot.
🎯 Clarity Across the Neck
You’ll learn how to navigate the fretboard effortlessly using diagonal arpeggio shapes, so you’re never “stuck” in one position.
🌀 Musical Control
It’s not just about knowing the notes — it’s about making them sound good. You’ll build tone, touch, and rhythmic precision so your solos connect with the listener.
🎸 Real-World Musical Practice
Every lesson is designed to translate directly into your playing. You’ll use arpeggios over real progressions, practice with intention, and hear immediate improvement in your solos.
This isn’t a course that dumps a pile of diagrams in your lap and leaves you to figure it out. It’s a step-by-step system that gives you small wins every time you pick up your guitar.
And the best part?
You don’t need to practice for hours a day. With the right plan, you can make real progress in 20–30 minutes — and start hearing the difference in your music right away.
That’s what Mastering Diagonal Arpeggios gives you.
