The Sound of Music
summary
Argues that music is simply time-series data and demonstrates a working tool called node-keyboard that pipes MIDI and text commands through Node streams and soundfonts to produce audio. Shows how functional composition and Rx (distinguishing hot and cold observables) transform notes into modes by rotating the 2‑2‑1‑2‑2‑2‑1 pattern. Proves it live: mouse position and a filtered Twitter stream mapped to pitch (e.g. Bieber ≥500 followers, Clinton ≥10,000) drive instruments; the pipeline runs and produces audible, interpretable results.
