A context-aware interactive Piano tutor

See a piano tutor app using multi-level AI agents for real-time feedback. Learn about context engineering, AI tool orchestration, and architectural integrity for AI projects.

Overview

VibeKeys is a piano learning app designed to test the boundaries of interactive AI education capabilities.

I’l show an app demo where the student plays a section incorrectly, and how the voice AI agent is engaged to provide insight to the student through its multi-level agent orchestration and context engineering system. The app has an interactive context layer that allows low-latency responses for simple tool calling combined with more escalated handoff to a deep-reasoning “Music Education” agent.

I could also show some of the cool AI tools and skills I use to build this project:

Project-Specific “Pattern Languages” (Christopher Alexander) to help guide decision-making
BAML (open-source AI wrapper infrastructure that turns all LLM calls into statically typed function calls).
My code review process which uses Reviewable.io to host the diffs and interactively communicate with the AI agent to address review issues.
