Dr. Guy Shkolnik’s Music Theory Course

This course gives you a clear, hands-on understanding of music theory—structured, practical, and designed for real-world use.

If you're a self-taught or semi-self-taught musician, you've likely picked up theory from lessons, books, or online videos. But if those concepts still feel disconnected—or if you've forgotten much of what you once learned—this course will bring it all together.

“Unlike any other online course I've seen. Pinpointed to master fundamental skills.”

— Soubir Moitra, songwriter/producer

Maybe you've struggled with modes, felt uncertain about minor scales, or never quite understood why the circle of fifths matters. Maybe you've played for years but still feel like something is missing—relying on intuition without fully understanding why things work, or unsure how to take your playing to the next level. And when it comes to jazz chords, how exactly should you voice them? When do you use extensions like 9ths and 13ths? What types of progressions and styles do they fit into?

This course connects the dots and fills in the gaps. You won’t just learn theory—you’ll apply it through real music, guided exercises, and practical examples. Quizzes throughout the course ensure you're making real progress, reinforcing what you’ve learned.

I designed this course with one goal: to free you from the frustration of not knowing. Not with abstract theory, but with knowledge you can use—so you can play, hear, and understand music with confidence.

I can’t promise this course will make you famous. But I can promise it will remove the frustration of not knowing, so you can make music with clarity and purpose.

If you've ever felt like you were just “getting by” in music without fully understanding how it all works—this course changes that. For good.

    Dr. Guy has a very precise, application-based approach that feels very natural, which is why I started following him on Instagram — a paget 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 that are 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. So the course develops with you, which I think is fantastic.

  • This course was transformative!

    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.

    –Manar Abbas, Jazz Singer

  • One of the best learning experiences

    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.
