About Note & Key
Note & Key — version 1.0.0. Built in Langley, British Columbia, Canada.
What it is
Note & Key is the back office for a private music studio: the schedule, the students, the practice recordings, the invoices, and the year-end totals — in one place, on the web and on iPhone.
It is built for the teacher who is the studio. Most music-school software is designed for an institution with an administrator, and is priced and shaped accordingly: seats, roles, approval chains, a front desk. A teacher with twenty students and no front desk ends up running the business on a calendar, a spreadsheet and their memory of who paid — which works until roughly February.
Why it exists
The hard part of teaching privately is not the teaching. It is everything arranged around it: who was taught this month, who cancelled with enough notice, who is owed a makeup, which e-Transfer was for which child, and what any of it added up to when the tax return is due.
Each of those is individually trivial and collectively a second job, and all of them are the same underlying record — a lesson that did or did not happen. Note & Key is built on that: mark lessons as you teach them, and the invoice, the attendance history and the annual income figure are consequences of the schedule rather than three separate things to maintain.
Who makes it
Note & Key is made by ZET Studios, an independent software studio in Langley, British Columbia, Canada. It is a small, independent product — not venture-funded, and not a side feature of a larger platform.
That shapes what gets built. Support email goes to the people who write the software, and a teacher describing a real billing edge case is usually talking to someone who can change it.
How it is paid for
By subscription, from teachers. There is no advertising, and student and family data is not sold or shared for marketing — what that means precisely is set out in the privacy policy.
Every new studio starts on a full month with everything unlocked and no card. After that the Free plan keeps one student going indefinitely, and paid plans cover a full roster. Prices are on the pricing page and are the same whether you subscribe on the web or through the App Store.
Where it runs
Note & Key is web-first. It runs in any modern browser on a laptop, tablet or phone, and there is an iPhone app. Your studio lives in your account rather than on a device, so signing in somewhere new brings everything with it.
The marketing site is available in German, Spanish, Japanese, Korean, Traditional Chinese and Simplified Chinese. We also publish free tools and guides for music teachers, including tax guides for Canada, the UK and Australia, which need no account at all.
