THIRI

THIRI is music theory infrastructure for the AI era. The next generation of music software is being built on AI, and that software needs harmony it can trust: answers a trained musician would sign off on, every time. THIRI exists to be that layer. It serves the developers and companies building tools for musicians, and it is what this operator builds when the assignment is infrastructure rather than a single business. The other four builds on this site each solve one operation. THIRI is built to sit underneath an industry.
