“Unlike any other online course I've seen. Pinpointed to master fundamental skills.”
—Soubir Moitra, songwriter/producer

This course is a complete foundation in harmony, designed for musicians who want more than just theory—they want to understand what they're playing.

You'll learn scales, chords, extensions, inversions, voice leading, modulations, modes, and more - but always in context.
I teach every lesson at the piano, showing exactly how these sounds behave inside real music, with examples from jazz, classical, and pop.

This isn’t an encyclopedia. It’s a path:

  • You’ll see where the chord comes from

  • How to voice it clearly

  • And how it resolves, sometimes classically, sometimes with that rich modern color

Each lesson builds on the last, and every concept connects back to real music you actually want to play.

There are quizzes, progressions, and PDFs for practice—but the real value is clarity.
If you've been guessing your way through harmony, this is the course that makes everything click.

Unlike any other online course I have seen

Soubir Moirta, Songwriter/Producer

Dr. Guy has a very precise, application-based approach that feels very natural, which is why I started following him on Instagram, a page that’s a goldmine of information in itself. This course offers easier and more concise access to specific tools and information, pin-pointed to master skills fundamental to a strong musical foundation. I recommend it to anyone who truly wants a solid grasp of complex musical concepts. It opens up a lot of avenues, and the best part is that it gets updated, unlike any other online course I’ve seen. The course develops with you, which I think is a fantastic foundation. I recommend everyone with a desire to truly have the freedom to play what they imagine and to have a strong grasp over complex musical concepts to thoroughly go through this course.

"Being self-taught on piano, Dr. Shkolnik’s Music Theory course was the perfect introduction to ‘real’ music theory I’d been looking for. The video lessons alone are worth the price, and I especially appreciate his use of popular music examples to show what’s happening harmonically. The PDF printouts live in my notebook, I still use them in my practice and when I need a refresher on modes or chord extensions. A great investment of time and money - highly recommended.”

I recently had the pleasure of taking an online music theory course with Dr. Guy Shkolnik, and I can confidently say it was one of the best learning experiences I’ve had in a while. Guy is not only a talented musician but also an excellent teacher who knows how to explain complex concepts in a way that's easy to understand. –Milad Mohsenian, Jazz Pianist, educator.

As someone who has always learned random tidbits about chords but never had a clear understanding of what makes a chord what it is, this course was transformative! Guy teaches at a super comfortable and approachable pace and does a good job of covering the basics and building from there. Before the course, I had spent so much time searching and finding complicated answers for things he explained so simply. You’ll leave the course understanding enough to learn to play your favorite songs or to compose your own.

Dr. Guy is an exceptionally professional teacher and a talented musician. I recommend this course to students of all skill levels, from beginners to experienced professionals.

FAQ

  • Do I get lifetime access to this course?

    Absolutely.

  • I’m a guitar player. Is this course for me?

    Yes, it is. I explain everything at the keyboard because harmony is easiest to see and understand there. But don’t worry, what I play is not technical, and you won’t have any problem following along. If anything, this course will teach you that clear, minimalist, professional-sounding keyboard approach that can elevate your productions and arrangements.

  • Do I need to be able to read music to learn from this course?

    No, you don’t. I explain everything at the keyboard. That said, I’ve also included a PDF with all the main progressions from the course. So if you do read music or even just a little and want to improve, the PDF will definitely help.

  • Do I need a piano/keyboard to learn from this course?

    Yes, you'll need a keyboard of at least four octaves (49 keys) to practice the progressions and the tutorials of this course.
