Is the Guitar Fretboard a Mystery to You?
Tired of the hunt-&-peck, trial-&-error, random YouTube approach?
Are you beginning to think there must be a better way?
How about the latest cool song that you’re into? Can you figure it out on your own or do you have to laboriously work through a tab chart you got online that you hope is correct? (It’s probably not.)
Have you ever sat in a music theory class wondering what the rules of the four-part Bach chorale style have to do with the guitar?
Have you ever heard some awesome guitarist play and wondered how anybody could know so many chords?
Or what bizarre scale is he using that sounds so cool?
Do you understand this symbol?
- or does it look like some kind of calculus problem?
IS THE GUITAR FRETBOARD A MYSTERY TO YOU?
My name is Jay EuDaly and I've been a professional, full-time guitarist for over 50 years. My method, Vertical Truth: Chordal Mechanisms for the Guitar, can help you remove the mystery.
What makes my method any different from the plethora of guitar education websites out there peddling guitar lessons? Well, if you really want the complete answer to that question, read A Little Story. It will give you the detailed history of this unique, time-tested & proven method, and why I am the guy to lead you through it.
The short answer is that this method takes you step-by-step through about 1,000 years of music theory evolution and APPLIES IT TO THE GUITAR. As a result of doing this - not just understanding, but DOING - many things happen automatically;
you gain a complete understanding of the guitar fretboard,
you learn how to think about music and the guitar,
you develop good technique and
you train your ear
- to name just a few things that happen organically as you work your way through this method.
You can then apply your knowledge
to ANY STYLE!
To get started, take these first few steps:
Become a Master Guitar School site member - it's free. You will then have access to dozens of free lessons in the "Members Only" area of the website. You will also receive the Master Guitar School Newsletter. Most of the monthly newsletters contain a free lesson. Members are also periodically offered first access and deep discounts (50% or more) on new lesson series downloads when they are first published. For more information go to:
Go through the 5-Lesson Foundational Series. Everything is based on it.
Master the first 2 Major Scale patterns given here. There are 6 Major Scale patterns given in this lesson but only the first 2 are required to get started.
Communicate with me. Let me know what you'd like to see as far as lessons go. My agenda is to rewrite and format my method book, Vertical Truth: Chordal Mechanisms for the Guitar, into PDF/video downloads. That process is underway. You can see what's currently available in the column to the right (or below if you're viewing this page on your phone). I'm also open to doing one-off lessons on any guitar-related subject you want, in any format you want (video, PDF, webpage etc.).

The guitar has been a Grand Obsession of mine for over 50 years. I love everything about it. I've been a full-time professional performing musician since the early seventies. I've taught 50-100 personal students a week since the early eighties.
I know what it takes to play, teach and learn. I'm passionate about playing as well as helping people obtain the priceless value that I've received from music and the guitar.
Is the guitar fretboard a mystery to you?
I can help.
What People are Saying
I’ve had three primary music mentors: Jay EuDaly in Kansas City, Ray McCarty in Austin Texas, and Max Bennett here in Southern California. I’m forever grateful for their wisdom, patience, and inspiration.
Not only is Jay EuDaly one of the greatest guitar players I have ever heard period, but he is also one of the most knowledgeable guitarists out there. Very few know the neck up and down as well as EuDaly. I call his Vertical Truth my guitar bible. Studying with Jay is the most complete guitar/advanced music education one can find anywhere.
I've been teaching guitar online since 2004 and I can tell you from a LIFETIME of experience that you won't find anyone with a Better Guitar Method than Jay EuDaly! He's my personal guitar coach and I highly recommend anyone from total beginner to experienced pros to spend some time with Jay, you'll be glad you did!
Jay is one of the best guitar players/teachers in Kansas City! Superb player and extremely knowledgeable in music theory which he learned from the late, great John Elliott.

...the way you lay out the circle of 4ths on the guitar neck is a new revelation to me and I've been searching for this sort of stuff for four years online! I've spent the last 2 weeks practicing the stuff in the free lessons and have enjoyed it on a daily basis. Already familiar with some of the scale fingerings and found the key cycle a brilliant way to run them all! Very smartly laid out and easy to put one thing on top of the other. Feels like very little wasted time practicing and I can't tell you how much I appreciate that! An hour of practice flies by in no time and I actually feel like I'm accomplishing something!
- Frank DiNuzzo
I have been puzzled about the fretboard for decades! Thank you for the most intelligent approach to teaching guitar I have ever encountered! I was astounded to follow your lessons and reasoning, and find that all of a sudden I could see the fretboard as something intelligible and not as a jumbled mess! I know the circle of fifths because of piano but had never looked at the other way as a circle of fourths and how to apply that to the fretboard! Who teaches that??? Only you!

September 20, 2021: Jam Tales: José Hendrix: Sometime in the Spring of 2011, a singer from the Democratic Republic of the Congo (DRC) sat in at the Saturday Afternoon Jam at BBs. His stage name was José Hendrix. He lives in Kinshasa, the capital city of the DRC with a population of 15 million. He was good, real good.
September 6, 2021: The Tritone Substitution (3): In this lesson I’m going to talk about what to play as a guitarist relative to Tritone Subs when there’s a bassist in the mix. I’ll use the I-VI-II-V Turnaround to illustrate.
August 30, 2021: The Tritone Substitution (2): The Tritone Substitution concept can be applied to any chord progression that moves cyclically, that is, a cycle of 4ths.

August 2, 2021: Republished: What's Wrong With My Hand? Knock-Kneed Knuckles.
July 26, 2021: Republished: What's Wrong With My Hand? Angular Dysfunction. This one addresses the tendency of the fretting hand knuckles to be held at an angle relative to the fretboard rather than parallel to it. When this angular dysfunction is in play the pinky, which is the shortest finger, has to reach the farthest - that's backwards.
July 19, 2021: Republished: What's Wrong With My Hand? Listin' to Port! This one addresses the tendency of the fretting hand to drift towards the headstock, thus fingering the backside of the fret which raises the likelihood of muted notes &/or fret-buzz.

July 12, 2021: Republished: What's Wrong With My Hand? Random Pinky! This is the 2nd vlog in a series on common technique issues. This one has to do with controlling the movement of every finger of the fretting hand, all the time, so that your fingers are never more than a fraction of an inch from the strings. Less movement = speed, accuracy and stamina.

June 14, 2021: The Mixolydian Distinctive: The basic concept of this "Modal Distinctives" series is that you can get to the distinctive sound of a mode without learning the whole mode, but by adding, or altering, a single note of the most commonly-known scale among guitarists; the Minor Pentatonic. So how can you get a Mixolydian sound from a Minor Pentatonic? Easy. Just sharp the 3rd.

May 24, 2021: Blog: The Ionian/Lydian Distinction: The concept of this "Modal Distinctives" series is that you can get to the distinctive sound of a mode without learning the whole mode, or getting all confused by modal theory, but by adding, or altering, a single note of the most commonly-known scale among guitarists; the Minor Pentatonic.
May 17, 2021: Blog: House Gigs: Familiarity-Creep: A huge percentage of the time, getting a house gig is the beginning of the end for the band. It's a very seductive thing; steady work, regular paycheck, there's usually a "scene" happening and you are right at the center of it. But inevitably, "familiarity-creep" happens and it usually doesn't end well. If you're lucky, it was a good run and was worth the flame-out at the end.
May 3, 2021: Blog: The Locrian Distinctive: “... I need to discuss the reasons why this sound is so specialized and the resulting confusion among beginning and intermediate players concerning its use.”
