Essential Theory For Guitarists

A comprehensive foundation of music theory knowledge on the guitar, as well as how to apply it in your playing.







About This Masterclass

Music theory is such a vast subject that can be very frustrating and hard to understand without structured guidance; especially in modern times where there are literally millions of conflicting methods and approaches across the internet. You’re surely feeling lost, confused, and you’re searching for someone to just lay it all out for you without over-complicating everything.

That’s why I’ve created “Essential Theory For Guitarists”, based on the knowledge that I once lacked as a result of confusion and naiveness, in hope that I can help a similar audience today.

This Masterclass is best suited for guitar players who are somewhat familiar with some basic principles of music theory, but sense many gaps amongst their understanding. The class has been designed to accommodate for both semi-experienced music theorists, and also complete noobs to the topic. I’ll be starting from the fundamentals, before gradually working through three core topics and how they all interlink: Scales, Chords, and Arpeggios. 

Whilst the primary focus of this class is to provide you with the knowledge, I’ll also demonstrate and teach you how to apply these topics throughout your own music practice.

The class includes over 4 hours of guided video instruction, backed with thorough lesson notes for each video, fretboard diagrams, tabs (PDF), backing tracks, lifetime on-demand access, and on-site support! Not only am I able to respond to your comments and questions directly, but you can also interact with other students from within the classroom.

You’ll learn all of the essential music theory concepts in a musical setting, so that you’ll be able to understand them and quickly apply them into your playing. For each lesson, I will first explain the topic clearly, and then demonstrate the concept for you to follow along. 

The course is organised into five sections. Click through the section names below to learn more about what each section entails…

As the name suggests, this section will prime you for the entire course and your entire outlook on music theory. If you want the maximum benefits from music theory then it’s very important that you have a solid understanding of intervals, which is the primary subject within this section of the course. I will give you a thorough understanding of intervals, as well as show you my methods of interval visualisation across the neck.

In this section you will acquire a thorough understanding of Pentatonics, The Major Scale, The Minor Scale, Modes, as well as the ability to Understand Keys, Diatonic Chord Sequences, Modal Chord Progressions. Most importantly, I will teach you how to apply all of these topics in your Songwriting, Musical Understanding, Visualisation, and Improvisation. All music theory is developed from scale knowledge, so I’ve taken extra care to make sure that this section of the course is very thorough, easy to follow, well annotated, and relevant.

You will learn all of the essential theory and practical applications of chords. After following the lessons throughout this section you will be able to confidently; build the 4 primary chord types in all areas of the neck, invert triads, visualise and play diatonic chord progressions in any key and area of the neck, and understand roman numerals in relevance to music theory. You will also be able to construct extended chord voicings such as seventh chords, suspended chords, slash chords, add chords, and more!

This section will combine much of the previously learned topics to help us understand and create Arpeggios. I will show you how to build your own arpeggios across the neck, as well as share some of the more common shapes that you will be able to use immediately. By the end of this section you will be able to confidently use Arpeggios in your Lead and Rhythm playing, in both Composition and Improvisation, whilst also aiding your Creativity and Visualisation of the neck.

You guessed it! This section will be a short overview and summary of the course and what you’ve learned, where to go from here, and I have also included a list of examples where I have applied some of these theory concepts to help inspire you further.

A gem of a course from a gem of a player/teacher. Hands down winner here. I've learned so much from Darryl. Thank you!

I haven’t finished this course as I’m being as thorough as possible but its already provided so many incredible tools and lessons for hours of endless learning. It’s already a 5-Star course in my book. Darryl is an incredible teacher and player that has heaps of wonderful insight to the basics of guitar and music theory. Not to mention his tasteful playing is such an inspiration to my own. I’ve learned so much here and on youtube and I have you to thanks Darryl! Thank you. I love feeling the progress and finding connections through your lessons and my everyday playing. Hope to become my own best version of musical self on my guitar journey.
Personal side note as someone who has play guitar for over a decade and never learned a lick of theory. As I move through the course I make sure to take breaks in between learning the course material and try to apply it to both writing and learning other musicians music. I then go back and try to take a deeper dive and truly learn the theory behind what I’m playing and not just “memorizing” the shapes but really understanding the intervalic value and understanding what I’m playing (I happen to be learning triads). I find this more digestible and advise other to do the same if it feels overwhelming. I compare it to learning a new language – if you just memorize a sentence/words do you really know what your saying? It takes time and effort to truly understand it all. Multiple visits to the same lesson is it’s own lesson I’m learning! – You’re your own boss when truly learning and no ones watching so make it count! Good luck to everyone!

A truly brilliant course and unbelievable value!

This course is absolutely fantastic (and worth way more). If you want a better understanding of Music Theory then this is 100% for you. The structure of the lessons and the content proves that Darryl not only can play the guitar (obviously) but can TEACH it too which is rare. I feel I’m already improving and actually understanding what I’m doing rather than just relying on memory. You get the structure, content, transcripts for every lesson, PDF’s when needed, and can ask questions too. Honestly, it’s been the best purchase in my guitar learning journey so far. If you’re thinking about it, get it! Thanks so much, Darryl.

The value and what you get for the price is insane

I think the title of this class already said it. This has helped me a lot. Darryls way of teaching things is clear, easy to understand and logically build up and he is a calm very kind guy. Definitely would buy it again. 10/10!

This is definitely the best course for learning guitar music theory.

I’ve been buying lots of programs and watched youtube videos on music theory but never really understand them too well, but Darryl sets this program in an understandable order. Thank you so much, would definitely buy other programs too when you make them. Currently halfway through this program haha

I LOVE the transcripts written out for every lesson, that compliment the videos really well.

Absolutely great course so far, highly recommend it. It is thorough, easy to understand and covers all the topics which I’ve heard mentioned before, but never understood, in one comprehensive course. One of the things that I LOVE about it are the transcripts written out for every single lesson that compliment the video lesson really well. I love watching Darryl explain the topics in the videos, but I really like being able to have something to read at my own pace and study. The notes are very thorough and super helpful. Another thing worth mentioning is the support that you receive if you ever have any questions. He always replies really quickly with a thorough answer and clearly values his students. Highly recommend this course. A++

A must for all guitarists I feel.

Brilliant course, covers everything I wanted to learn to understand what I’m playing more and also unlock a vast amount of possibilities with my guitar playing. The guitar has definitely just opened up to me, and also a deeper understanding of music in general and how it can be worked out on other instruments.

Love how thorough the lesson notations are!

Recently bought and went through Intervals real quick to get an idea of the course. What really caught my eye was the notations to go along with each lesson. Very thorough and useful for someone like me who likes to keep notebooks of information. I’m excited to put it to use and start feeling more comfortable with creating music instead of blindly playing what MIGHT sound good. lol Thanks, Darryl for the opportunity to learn from you. Some of your vids on Youtube go over my head when it comes to theory, but I’m eager to learn!

Your teaching and your skills are like no other on the internet!

Hey Darryl, first off thanks for all that you do!! I’ve been playing guitar now for over 20 years self taught. Thirteen of the years I’ve been fortunate enough to do it for a living. I’ve learnt so much from this course as well as your YouTube videos, there’s just so much useful information. I would definitely recommend this course to anyone who’s starting out or has been playing for sometime. If you want to take your guitar playing to the next level this is the teacher you need to follow for sure! If I could give more than 5 stars I would. Thanks Darryl, I’ll be signing up soon for your Patron as well as your Skype lessons soon take care.

This is a great course for learning guitar music theory!

This course helps me to understand complicated guitar theory in an easy way and very easy to understand. I recommended this course, especially for a guitarist like me, I’ve been playing electric guitar for many years, but I only have basic knowledge of guitar theory. To be honest, this course helps me to improve as a guitarist and helps me to improve my musicality. Thanks, Sir Darryl for this intuitive course.
