About
Jazz Wiki is an open knowledge base for jazz — the theory, the harmony, the history, and how it all connects. The goal is simple: take a body of knowledge that usually lives in expensive books, scattered lessons, and players' heads, organize it clearly, and make it freely accessible to anyone, arranged so each person can learn in the way that fits them.
Great knowledge shouldn't be hard to reach. In the spirit of making information universally accessible, Jazz Wiki treats every concept as a first-class page you can land on, read, and share on its own — and as a node in a larger map you can explore by connection. There's no single "right" way through it:
Every note aims to explain from first principles, in plain language, with concrete musical examples and real recordings to listen to — the way a good teacher would. It's a living project: 310 notes so far, and growing.
Hi, I'm Daniel Rosen — a jazz enthusiast who has played guitar for most of my life, and picked up the clarinet two years ago. I work in tech, where I spend a lot of time with AI agents and knowledge bases, and Jazz Wiki is where those two worlds meet: a side project built entirely with AI agents.
I believe information should be free. This project is my attempt to organize jazz knowledge — usually scattered across books, forums, and lessons — into one open, connected place, so that anyone who wants to learn jazz online can actually find their way in.
One honest caveat: a site like this can teach you about jazz, but it can't make you fluent in it. Jazz is a language, and you don't learn a language by studying grammar — you learn it by speaking. There are no shortcuts: transcribe recordings yourself, with your own ears, and play with other people as often as you can. That's where the real learning happens. Think of Jazz Wiki as the grammar book and the map — the conversation is up to you.
