AI Research

bachx project

I'm building the framework of a music analysis AI agent for the Bach chorale corpus. Using harmonic analyses from the "When in Rome" project (thank you Mark Gotham), I'm developing a self-hosted chat agent around the Qwen LLM. Over the next few weeks I hope to expand the project by tuning it, and adding additional layers of music-theoretic knowledge on top of the existing harmonic analysis. Hopefully this will be useful not just because it's very cool but also as a way to teach students more about how to interact with AI, and about Bach!

The Latest: July 2026

I'm building some new queries and moving from a 7b to a 32b model. Very grateful to have an M5 with 48GB memory at my disposal, for working on this fascinating project!

bachx> what often follows ii?
