40 structured practice experiments.
10 small-group masterclasses to run them.
The last practice system you'll ever need.
You know you could be performing better.
Not for lack of effort, but for lack of something else.
It's inconsistent.
You're nervous.
Or you mess up the bowings just a little.
Or you change the fingerings just a little.
Or you never really settled on the phrasing right there, and it came off as bland.
In the practice room you can hit it at 100%.
But in performance, it's not there.
And you walk away frustrated, unsure what more you can do.
You are better than your last performance showed.
In 1 year, you'll master all 40 Popper Etudes.
That matters.
But more importantly, you'll use them to run 40 structured practice experiments.
After 1 year, you'll know how YOU learn fastest and perform most reliably.
And you'll use that knowledge for the rest of your career.
You'll spend 2 weeks per etude:
Week 1, you'll play with a 60-minute practice track to run the experiment.
Not because you need the guidance, but because the experiment is built in.
Week 2, you'll refine in 30 minutes while starting Week 1 of the next etude.
After 5 weeks, you will have run 4 overlapping experiments.
You'll choose 1 etude and perform it in a masterclass.
The point of the masterclass isn't to play perfectly.
It's to see the results of one experiment played out.
By the end of the course, you'll have a complete practice system.
My practice is so systematized that...
I know exactly how long my practice will take, down to the minute.
I miss zero notes in the practice room.
For the last decade, I have had zero performance anxiety.
This course is designed to give you the same results:
The practice techniques you build here
transfer
to everything you play
for the rest of your life.

“I consider this course so far to be some of the best money I've ever spent, it's had a huge impact on my practice and teaching, and I find I'm able to learn things much faster applying these methods. Thanks for all the work you're putting into this, and knowledge you're sharing with us.”
Ethan W. — professional cellist
“I've been using this in my practice for my cello teacher and I just learn it all so much faster.”
HIGH SCHOOL STUDENT
“When you introduced [one of the practice techniques], I started teaching it to my own students and saw instant progress. I couldn't believe it.”
ENROLLED CELLO TEACHER
“A lot of fun!”

CRISP stands for Clarity, Repeatability, Intensity, Speed, and Progress. It is the advanced practice methodology at the heart of the Proper Popper Practice Project, applied to each of the 40 Popper Etudes. CRISP is the fourth of Cellosophy's Four Practice Pillars: SMILE, FIELD, PRISM, and CRISP.
This Course is designed for cellists who have played at least 2 concertos and are fluent in 4 octaves. If you have studied the Poppers before, even partially, you are ready. If you are unsure, take the free practice scorecard or schedule a call.
Yes. This Course teaches practice technique, not cello technique. It is designed to work alongside your private teacher, not replace them. Several enrolled cello teachers use it with their own students and vice versa.
The Course drips weekly but you have lifetime access to all materials. If life gets in the way, pick up where you left off. The system is designed around consistency, not perfection.
You'll participate every 5 weeks in 10 of the 20 masterclasses spread across the year. During every 5-week block, there are two masterclasses spaced 2 and 3 weeks apart. If you can't make one or need a little extra time, just hop onto the other track and then continue every 5 weeks from there. All sessions are recorded so that participants can rewatch themselves. Recordings are made available only to PPPP enrollees.
Week 1 of each etude: a 60-minute guided practice track. Week 2: 30 minutes of refinement while starting the next etude's 60-minute track. You always know exactly what to practice and for how long.
Yes. The same edition required at Juilliard and the University of Michigan since 2012. Digital and print copies, and Eric's own personal teacher's edition, are included with enrollment.
Most cellists work through the Poppers in order, focusing on the notes. This Course reorders them by technique and theme, and uses each etude as a structured practice experiment. The goal is not just to learn the etudes. It is to build a complete practice system you will use for everything else you play.
This Course is not for beginners or early intermediate players. You need at least 2 concertos under your belt and fluency in 4 octaves. If you're not there yet, start with the Practical Popper Prep Course.
Yes. Enrollment includes the Aaron-Moore Popper Etudes edition (the same one required at Juilliard and the University of Michigan) in both digital and print formats, plus Eric Moore's personal teacher's edition with annotations.
You'll participate every 5 weeks in 10 of the 20 masterclasses spread across the year. During every 5-week block, there are two masterclasses spaced 2 and 3 weeks apart. If you can't make one or need a little extra time, just hop onto the other track and then continue every 5 weeks from there. All sessions are recorded so that participants can rewatch themselves. Recordings are made available only to PPPP enrollees.
Yes. PPPP enrollment includes access to the Cellosophers Forum, a private community where enrolled students share progress, ask questions, and support each other.
A 20-week program built directly into the PPPP that addresses the mental and emotional side of performing. It's woven into the weekly curriculum, not a separate add-on.
Students have described it as "some of the best money I've ever spent," reporting faster learning, more structured practice, and significant improvements in both their playing and teaching.
Yes, but it does require 90 minutes a day of your practice time. Students who were studying with a teacher all reported that they learned their lesson music much faster and at a much higher level. Our hope is that the speed boost in learning evens out with the 90 minutes you're adding. That said, the PPPP is a fantastic way to up your practice time.
Yes, but not in the way you might expect. You'll run 52 practice experiments, one per week, which help you confront different technical challenges. Each experiment gives you data so that when you encounter those challenges again, you know the fastest way that you personally tackle them. You will develop technique by doing the etudes, but more importantly you'll develop the skill of practicing those techniques when you encounter them in other music.
Each week focuses on a specific technical or musical challenge drawn from that week's etude: string crossings, thumb position endurance, spiccato control, phrase shaping, and dozens more. You don't just practice the etude. You isolate one variable, test an approach, and record what works for you personally. Over 52 weeks, you build a personal library of practice strategies that transfers to everything else you play.
The PPPP will help you develop the ultimate practice system, tailored to your own preferences. You should emerge with all the data you need to create a reliable, scalable practice system that lasts for your entire career. You will know, down to the minute, how long it will take you to learn and master any piece of music you encounter. There are no further Courses in the Practice Pillar sequence because you will have mastered your practice.
Everything in the Proper Popper Practice Project plus a 30-minute weekly lesson check-in on the etudes with Eric Moore. It's designed to give you extra support if you're concerned about the challenge, although in that case we would recommend completing the Practical Popper Prep Course first. The Premium Track is also designed for professionals applying the Course in real time to their concert music, and for audition preparation at the college or orchestral level. One professional student used it to prepare for orchestra auditions and a college professor used it to prepare for international concerto performances. You can schedule a call to discuss.
Unfortunately, Eric's studio is full to capacity. He'd like to chat with you about what you hope to gain from the additional 1:1 support. You can schedule a call to discuss.
Students as young as 11 have completed all 40 Popper Etudes with Eric. A handful of students have been under college age, a few in college, and a few have been adult amateurs, although most PPPP students have been conservatory graduates with at least a master's degree. The Course works for any advanced cellist with at least 2 concertos and fluency in 4 octaves.
Yes. You will receive a certification upon completing the Course. Certification requires attending all 10 masterclasses.
The PPPP ($4,299) has Pay Over Time options at checkout. Your payments also roll forward: your $99 from the 30-Day Challenge and your $499 from Popper Prep both apply as credit.
