# 🎼 QUANTCLASSIC

A quantum radio for the classical canon. Raise the baton and **every great theme plays
at once** — Beethoven's *Fifth* and *Ode to Joy* and *Für Elise*, Bach's *Toccata*,
Mozart, Vivaldi, Pachelbel — so quietly, and so out of step with each other, that
together they are almost nothing. That is a **superposition**: all at once, and none.

Then **click a voice to measure it.** Its wavefunction collapses — it swells to the
centre and rings out alone while the rest hush to a whisper. Measurement picks one voice
out of the chord, exactly the way it picks one outcome out of a quantum state.

- **▚ superpose all** — release the measurement; the whole canon blurs back together.
- **⟳ quantshuffle** — let it keep measuring itself, a random voice every few seconds.
  Schrödinger's playlist as a radio.

Everything is **public domain** and **synthesized live** in the browser (WebAudio) — no
recordings, no files, no trackers. One `index.html`. Sound needs a tap to begin (browsers
require a gesture before audio).

🜂 **AHOGY A DOLGOK VANNAK** — measurement collapses the chord to one voice, as things are.
