Glass Harmony
Glass Harmony is an interactive browser instrument built with procedural 3D glass cups and real-time Web Audio synthesis. Strike eight individually tunable glasses by clicking, tapping, or pressing number keys. Adjust each cup's water level with a slider to change its pitch — more water lowers the note. Choose from three cup sizes (Small, Medium, Large) to expand your tonal range. Tune all eight glasses to C major in one click, or calibrate each cup manually. Record your performance as a WebM file with synchronized canvas video and synthesized audio. All sound is generated at runtime with oscillators, envelopes, and room processing — no samples or external audio services required.
