Review practice between lessons and catch problems before they become habits.
Module 1Motion Music
Explore legato, staccato, dynamics, and phrase length through movement.
Module 2Performance Analysis
Practice a short excerpt or upload a full take. The report marks where to listen again.
Research BoundarySupports Teacher Review
The system suggests places to review. The teacher makes the final judgment.
Data and Research Notes
During analysis, the system records material type, excerpt range, detection results, teacher labels, and user feedback so the criteria can be improved over time. When minors or school-based data are involved, parent or guardian consent and proper data authorization are required.
This system is not a medical diagnostic tool. Pain, injury, rehabilitation, or occupational health concerns must be reviewed by qualified medical, rehabilitation, or performing-arts health professionals.
About
From the Track to the Keyboard
I’m Xinhao Sun, a pianist, teacher, and piano education researcher. Piano Motion Lab connects my work in movement, performance, and teaching.
Movement Background
I trained in the 400 meters and 400-meter hurdles and competed at city and provincial levels in China. That experience shaped how I think about coordination, timing, and efficient movement.
Questions from Piano Teaching
Students often hear “relax,” “unlock the wrist,” or “shape the phrase,” but these ideas can be hard to feel. My work asks how movement, sound, and musical intention can become easier to understand.
Research Direction
I study Piano Performance and Piano Pedagogy at the University of Kansas. My work explores body coordination, musical expression, and Dalcroze-inspired learning.
Piano Motion Lab
Piano Motion Lab turns hard-to-describe playing experiences into visible, reviewable practice cues. It supports teaching without replacing the teacher or defining music through data.

User Notice and Risk Disclaimer
Please read this before using Motion Music or Performance Analysis. This system is currently a teaching-support and research prototype, not a medical diagnosis, treatment recommendation, or formal performance grading tool.
Purpose
This system helps students, teachers, and researchers observe relationships among body motion, musical feeling, sound results, and teaching feedback. Generated content is for teaching observation, practice reflection, and research records only.
Movement and Body Safety
Motion Music uses the camera for real-time interaction. Use light movements in a safe space; avoid large, fast, or uncomfortable movements. Stop immediately if pain, dizziness, clear fatigue, or discomfort appears.
Video and Personal Information
The Performance Analysis module mainly works with recorded videos. Uploaded or saved videos, audio, MIDI, student information, and teacher labels may contain personal information. For minors, use it only with informed consent from a parent or guardian.
Model Error
The system uses pose detection, hand landmarks, and sound analysis to generate preliminary results. Due to camera angle, lighting, occlusion, device performance, and model limitations, results may contain errors and should be reviewed by a teacher or professional.
Non-Diagnostic Statement
This system does not diagnose disease and does not replace advice from physicians, rehabilitation specialists, physical therapists, or other health professionals. Questions related to discomfort, injury risk, or rehabilitation should be directed to qualified professionals.
Data Storage
Some records in the current prototype may be stored locally in this browser. A formal school collection or server version should provide separate data authorization, privacy notice, withdrawal method, and retention period.

Performance Analysis Setup
Check Camera Placement First
This step helps the piano video, audio, and teacher labels line up for later review.
Normal capture only needs Primary Angle A. Angle B is optional.
A Primary Angle
Place it in front of the keyboard's right end, about 45 degrees from the performer's front-right side, showing the full upper body, hips, elbows, wrists, both hands, and keyboard. Avoid the right-rear side.
Optional Angle B
Use this only when you need a closer look at the keyboard, both hands, wrists, and forearm direction.
Hand Tracking
Hand tracking helps identify wrists, fingertips, finger opening, and left/right hands.
