WHY PRACTICE GETS STUCK

You can hear something needs work. The hard part is knowing what to change.

Repeating a passage more times won’t tell you what needs to change. PAI Erhu Coach helps turn a vague problem into one clear target, one useful change to test, and one thing to notice—so each attempt gives you information you can actually use.

“I built the practice coach I wish every erhu student had between lessons.”

Jeffrey Pai

Jeffrey Pai

Professional Erhu Soloist & Instructor • 24+ years playing • 13+ years teaching

I’ve spent most of my life with the erhu—first as a student of Professor Yang Zhong Cai, then as a performer, and for more than a decade as a teacher. Again and again, I saw the same problem: students could receive good advice in a lesson, then sit down to practise alone and still wonder, “What exactly should I change?”
That question became the foundation of the PAI Method—Practice, Awareness, and Intention. Instead of simply repeating a passage and hoping it improves, I teach players to work toward a clear result, test one relevant change, notice what happens, and keep what actually helps.
My background includes a Professional Stringed-Instrument Performance Diploma, serving as First Chair Erhu with the Canada YC Chinese Music Orchestra, and awards including Gold with Outstanding Musicality at the Stanford Baipu competition and Silver at the Dunhuang Cup North America competition.
I’m also the creator of the Erhu Fundamentals Masterclass (EFMC), my structured online erhu curriculum, and Erhu Labs, my guided-practice program where students work through technique, repertoire, and real playing problems with me.
PAI Erhu Coach brings that same teaching approach into your daily practice—so you can get useful guidance between lessons, work through problems more independently, and bring what you discover back into your music.

Honestly, Jeff's course is absolutely amazing. It’s very easy to follow at your own pace. In the 2 hours I did with Jeff, I learned more than the 9+ months with my teacher. Jeff’s methods were easier to relate to. The way he explains things even though it’s online is really easy to follow and learn from.

Jeff offers the most high quality and professional video lessons on the internet right now. Even in an online format, no bad technique or posture goes unnoticed by Jeff. His ability to expertly diagnose the root cause issues that are holding you back, and effortlessly communicate how to adjust your technique and hand/finger positions to overcome them, has been absolutely pivotal to my development as a player.

There are no instructors for erhu where I am and music stores don't even know what an erhu is. Jeff's EFMC course is so worth the time and money spent. As a former teacher of the arts, it's a very complete, concise course that builds a strong foundation to grow with.

I've been taking lessons from Jeff for about 6 months, and he is a great teacher… I started as a total beginner on erhu, but had previous experience with violin, and Jeff has taken that into account in tailoring lessons to me. I am learning very quickly with him, and would definitely recommend him to anyone looking to pick up the erhu for the first time.

I played the French horn in middle school more than 20 years ago, but I’ve had no formal training with any kind of bowed instrument. Jeff starts out with the most basic fundamentals of how to create a clean sound before he ever even talks about playing specific notes. I personally think it’s a great approach to learning the erhu.

What should I focus on today?
02:23 AM
Today, focus on making one string crossing more continuous by observing your bow path and testing one small timing change. This matters because a clearer transition can improve tone, rhythm, and confidence without asking you to change everything at once.
02:23 AM
I only have five minutes today. Can you shorten the string-crossing activity without losing the useful experiment?
02:24 AM
Absolutely! I’ll reduce today’s session to a quick baseline, one focused bow-path experiment, and a matched retest so you can still make a clear comparison and save one useful discovery.
