Making Music! In Emacs?!

" summary

Builds zmusic inside Emacs and describes concrete choices: uses Emacs text properties and font rendering, implements the WAVE file format by writing samples to disk, and shells out to the native player because Emacs blocks on playback. Recreates a looped composer inspired by the Android app anti-stress, supports scales (defaults to minor pentatonic), implements silent-note data for file output, hits quirks like zero‑width‑space spacing and overlapping playback interference, and shows a working but imperfect prototype.
