It's been years in the making. This is the first look at something I've been quietly building between rehearsals, concerts, and lessons: Arco.

For years I watched the best moments of my lessons disappear. The careful walkthrough of bow distribution and rubato in the Tchaikovsky. The breakthroughs in phrasing and sound. As a student and later as a teacher, I tried every system to hold onto them — notes, recordings, voice memos. Nothing worked the way I needed it to.

Arco is what I wish had existed.

When AI finally made it possible, I knew it had to be built. Many lines of code later, it's the first tool of its kind — not just in music, but in education. Today I have over 1,000 lessons inside Arco. It holds my detailed thinking on every topic: the hundred different ways I've explained sound production to different students. And it can draw on all of it: to prepare a lesson, shape an article, even outline a book about my own method. Every lesson I teach makes it sharper. That's what I want for you.

Arco is now live and ready for you! Much more content is coming soon with demonstrations and how-to videos using this powerful new tool.

— What Arco does —

Record any lesson on your iPhone, iPad, or the web. Arco writes the
transcript and intelligent Lesson Notes — then lets you ask your entire
lesson history anything.

• Record live, or import old audio and transcripts
• Detailed Lesson Notes for every lesson. Not just a 'meeting blow by blow'. Deeply pedagogical writing.
• Ask anything, grounded in your own lessons
• Arco draws on two things: your complete lesson history, and the wisdom of the great pedagogues — Galamian, Flesch, Neuhaus, Moyse, Tárrega.
• Lesson Spaces to share progress with students or parents
• Works for every instrument, genre, and language
