I built this to alleviate friction in student-teacher feedback loops. It provides tools that aid musical development through structured, visual coaching, serving as a definitive source of truth for repertoire, technique, and exercises.

The Friction
The Problem
Corrections get lost in ephemeral chat histories, forcing me to repeat explanations.
Students' practice feels fragmented across various sheet music apps or personal recordings.
Precise, moment-specific feedback is nearly impossible with simple text.
The Shift
The Solution
Upload: Students upload their practice videos directly to the platform.
Annotate: I provide timestamped feedback and draw directly on their fingering/posture.
Grow: Our teaching library grows over time.
