A browser music sandbox lets first-contact learners hear a concept before any install or account

An in-browser music sandbox (here Chrome Music Lab) makes first-contact music exploration possible with no installation and no account: open the page and start playing. The orientation-level value is lowering the barrier to first sound so a complete beginner can manipulate rhythm, pitch, or a visualization and hear the result immediately, before any notation or theory. This is the L0 posture of browser-first live-coding tools generally (Strudel, Hydra) — the tool runs where the learner already is, so the first exercise is one click away rather than a toolchain install.

Examples

Song Maker (g.co/songmaker) lets a beginner compose and share a short idea in a browser with no sign-up — the same zero-install posture Strudel and Hydra take at strudel.cc / hydra.ojack.xyz.

Assessment

Explain why a zero-install, no-account browser sandbox suits an L0 orientation session, and name one browser live-coding tool that shares this posture.
