Sphaerosymphony’s music engine turns air quality data into generative soundscapes. Choose a sensor ID or click a hex on the map to hear the evolving composition.
Sphaerosymphony now creates music live in your browser using a small, efficient sound system. It is generated from the selected station’s latest loaded air quality window (24 hours or 7 days), with no pre-recorded track.
Each sensor ID seeds the generator, so a station keeps its own musical identity. For the same station and the same loaded data window, you hear the same core composition. Melodies use repeated motifs with call-and-response variations, so a station can feel familiar without every bar being identical.
The result is a generated piece that stays coherent for a station while reflecting changes across the selected historical window.
PM₂.₅ (particles smaller than 2.5 microns) can reach deep into the lungs, even entering the bloodstream. PM₁₀ (particles up to 10 microns) mainly affect the nose and throat. Both are measured in µg/m³ (micrograms per cubic metre).
The map colours and music follow these bands – green means cleaner air and lighter music, while red and purple mean heavier, harsher tones.
