The person behind the product
Jimenez Julien, and why a music studio needed better paper
Publication director at MLJ, SASU, builder of PracticeSheet, and the address behind every reply this site sends.
Why I built PracticeSheet
The first studio I ever sat in belonged to a piano teacher with 38 students and a stack of spiral notebooks on the bench, one per family. She could tell you from memory what every one of those students was working on. What she could not tell you, and what visibly bothered her, was whether any of them had touched the instrument since Tuesday. Forty minutes of her expertise went out the door each week and disappeared into six days she had no window into.
I spent a season visiting studios in three states and asking the same three questions: how do you write the assignment, how does the student remember it, and how do parents find out what happened. The answers were a notebook, a photograph of the notebook, and a shrug. Teachers were not short of skill or care. They were short of a record, and the absence of that record was quietly costing them lesson time at the start of every session, and costing them students every spring when a family decided the lessons were not going anywhere.
PracticeSheet exists to close that gap without adding a single minute of work to a teaching day. The rule I set at the start still holds: if writing the week takes longer than the student needs to pack up an instrument, the feature is wrong and gets rebuilt. Everything else follows from that. Assignments carry a tempo and a count because a vague instruction cannot be practiced. Parents get a link and not an account because no studio should be doing password support for a grandparent on Sunday night. Practice logging takes ten seconds because anything longer simply does not happen in a real household at eight in the evening.
I am not a conservatory graduate and I do not pretend to teach anyone their instrument. What I bring is fifteen years of building small, sturdy software for people who run businesses on their own time, and a habit of sitting quietly in the corner of a studio with a notebook until I understand the work. Every screen in this product was drawn after watching a teacher do the thing by hand first.
Experience and expertise
My background is in operations software for owner-run businesses: the kind of tools that have to survive a bad Tuesday, a distracted user and a phone with two percent battery. Before PracticeSheet I built scheduling and record keeping systems for small service firms, which is where I learned that the feature people ask for and the feature that fixes their week are rarely the same thing.
For this product specifically, I work with a standing group of eleven teachers across piano, violin, guitar, voice and low brass. They see changes before anyone else, and they have the right to tell me a change is wrong. Three of them run multi-teacher academies, which keeps me honest about what happens when a front desk and a payroll enter the picture. I also read the practice research seriously, but I weight what teachers observe in their own studios above anything a study claims in the abstract.
How this product is built and maintained
PracticeSheet ships small changes weekly and never ships a change to student-facing screens during recital season without warning. Every number published on this site comes from aggregated studio usage over the 2025 to 2026 teaching year, and if a figure cannot be traced back to a query, it does not go on the page. Testimonials are published with the full name, role, business and city of a real customer who read and approved the quote.
Editorially, the standard is plain: no claim about outcomes without data behind it, no invented integrations, and no pretending a limitation does not exist. When something on this site is out of date, I correct it rather than quietly deleting it. Support requests come to my own inbox, and the person who answers is the person who can change the product.
