ADVANCED CELLO MENTORSHIP
The 5-Day Cello Accelerator
Personalized 1:1 coaching to master advanced repertoire faster than you ever would alone.
THE MOST DIRECT WAY TO WORK TOGETHER 1:1
You're at the level where one-off lessons aren't enough anymore. You need consistent, focused contact — someone inside your practice process who can help you build smarter, not just harder. That's exactly what this challenge is designed to do.
Think about the last time you started a major work. You had the technique. You had the passion. But somewhere between the first read-through and a polished performance, things stalled. Fingerings that didn't settle. Bow distribution that felt unresolved. Musical decisions made on autopilot rather than with conviction.
That's not a talent gap — it's a process gap. The 5-Day Cello Accelerator is how we close it, fast.
NOT AN ADVANCED CELLIST? We have options for you too! Email [email protected] to get info about learning the cello and/or beginner or intermediate mentorship options in our signature CelloSchool program.
What's included
- Five 30-minute coaching sessions with Juilliard School Masters of Music cellist, Mari Coetzee. Scheduled on five consecutive days or spaced to fit your life — you choose.
- Personalized repertoire work. Any major concerto, sonata, or solo work you're preparing — brought to life with intention and precision.
- Complete technical and musical guidance. Fingerings, bowings, phrasing, musical interpretation — and a personalized practice strategy to carry it all forward.
- More progress in less practice time. Intentional structure and real-time decision-making so every hour at the instrument counts.
What we work on together
Five sessions gives us something a single lesson never can: the ability to work on something, send you away to practice it, and come back the next day to refine it — over and over. That's where real change happens.
We'll build a strong technical and musical foundation for your piece from the very first session, design efficient practice systems you can use for the rest of your life, refine your musical instincts in real time, and establish a preparation approach that's sustainable for the demands ahead.
"The short, back-to-back sessions kept me accountable and in momentum. If we had met weekly, I would have procrastinated — this setup pushed me to take immediate action and actually make progress."
— Beste O., former intensive participant

"Mari is an extraordinary cello teacher. I have grown immensely. From technique to being able to play a variety of styles and pieces. My technique and playing continuously advances. My motivation and love for the instrument increases as well. Great practice strategies.
Jerome W.
"I came to Mari with close to 15 years of experience on the cello, all the while knowing that there was something missing in my playing. Not only were many fundamental flaws addressed, but through Mari's useful resources, practice strategies and structure, she has provided me with the means to rectify them. With an increasing understanding of my own instrument and the building blocks of proper learning, I can now approach practice with much confidence knowing that it will produce a desirable outcome."
Katy L.
"We've been taking cello lessons from Mari for 3.5 years now. We are so blessed to have found such a wonderful teacher! Mari is positive, calm and clear in her communication as she teaches as well as very knowledgeable and experienced. Mari motivates my daughter to practice by giving clear consistent assignments broken down into small parts as well as fun activities and illustrations that help her learn new skills and reach practicing goals. She encourages her to choose songs that she would like to learn and helps her work towards getting those performance ready. Mari gives many opportunities to join online classes with her and other cello students that teach them more about playing the cello, how to perform, how to deal with nervousness."
