Klangkörper is an interactive installation designed to experience music in a new way. The project invites participants to become part of a digital choir, represented as avatars on a projection screen. Through gestures and facial expressions, users can generate and modify sounds, which then harmonize with the tones of other participants—creating a shared musical experience.

When users step in front of the screen, a camera recognizes them and creates a unique avatar that mirrors the user simultaneously. As they open their mouth, their avatar sings like a choir singer. Users can shape the sound with simple movements. Raising or lowering their hands changes the pitch, while moving them closer or apart controls the volume. By switching microphones, they can choose between bass, tenor, and soprano. Mouth shapes like A, E, or O adjust the vowel sound. With more participants, a digital choir forms, inspiring interaction and shared harmonies.

We use TouchDesigner for real-time interaction, with hand and face tracking via the MediaPipe plugin by Torin Blankensmith and Dom Scott. Sound comes from MP3 recordings of  "Google Blob Opera", inspiring our project and enhancing the interactive choir experience.
