Field notes
Each market’s first live trade establishes a reference price, and later movement climbs or descends the selected scale. The controls include several meters and scales, plus rhythm modes that either blend events or allow free flow; the page caps that mode at eight notes per second per market. Browser voices synthesize the sound, while initial snapshots and reconnect history are deliberately kept silent.
