Learning jazz piano on your own is daunting. There’s so much information on the internet and you don’t know what order to practice things in.

It’s overwhelming because the internet gives you ALL of the information at once – rather than showing you a clear path. You watch one video, and then have 10 other suggested videos thrown at you – all of which look just as important.

When I started learning jazz piano I looked to the internet also. I found some cool things here and there, but there was no core to what I was learning. Just random details scattered about. It never gave me confidence, and in fact, it took away my confidence because I felt like there were a million things that I should be practicing.

At the piano I’d flit back and forth between different things – 5 mins on improv, 5 mins on walking basslines, etc. But I never progressed. Most of my time was wasted TRANSITIONING between each area, rather than mastering any one.


However, everything changed for me when I started meeting with a jazz piano teacher in person. For the first time I was given just ONE thing to focus on (left hand voicings). Then we’d meet again and I’d be given the next thing to focus on (playing voicings in inversion). At the next lesson we’d tackle the next thing (Tritone Substitution), and so on.

The feeling of overwhelm disappeared and I found myself enjoying the learning process. I had just one teacher showing me the way, and I only had to focus on one thing at a time.

When I started learning through one source I improved very quickly. The bulk of my progress happened in just four months, and in less than two years I became completely confident in my jazz piano playing. We’d covered everything from the ground up and I’d filled in all gaps to my knowledge.

My name’s Julian Bradley. I’m now a professional jazz pianist and educator, with a masters degree in music.

I realize how lucky I was to have one person showing me the way, and now I want to help you achieve the same goal.

Ray HuckellRay Huckell, (Toronto): “When I decided to learn jazz piano 5 years ago, I searched high and low for a competent teacher who could lead me along the trail of developing a JAZZ SOUND. I lucked in to Julian Bradley on YouTube, watched every video he presented, made copious notes and went through the horrors of “oops, which video did he use to show his favorite major 7th voicing”. All of that is in the past as Julian has now published the most understandable explanation of the complexities of Jazz Piano and Theory. Terrific and easy to understand, what every visitor to your videos is praying for – a true GOLDMINE!”.

Steve Schneider, (US): “I am incredibly impressed with your easy clarity, your ability to convey complex material in an accessible and engaging manner, and your ability to focus on what’s really important in a logical fashion. I purchased your Jazz Theory Explained ebook and within 5 minutes knew that it was exactly what I’ve been looking for for years. Thanks for making all your hard work so accessible.”

Mike Le, California: “I bought your ebook and loved it! So much valuable information with detailed explanation. Your book is worth every penny!!!”

Roger Price, Venice, California: “I waited weeks before writing this email, because I wanted to see if your jazz theory book would clear up years of jazz theory confusion and frustration for me. Well, I’m happy to report that it has! After reading your book from cover to cover, I’m now able to practice “Dancing With You” on my piano […] Thank you so much!”

Ed Marsh, Oakland, California: “Hey Julian, The book is fantastic! I have been taking ‘expensive’ Jazz Piano Lessons for almost three years. My technique has improved and I’m enjoying the lessons, BUT I gained tons of ‘understanding’ from just reviewing, what I thought I understood and reading your e-book. Keep the e-books coming! Thanks, Ed”
