Lantern Rain: Original Strudel Soundtrack

Compose an original 80-second instrumental miniature called “Lantern Rain” for quiet-focus listening in a small creative workspace, reading session, or reflective product interlude. It should begin solitary and rain-lit, gradually feel warmer and more companionable, earn one gentle lift, and return home without becoming cinematic, corporate, or busy.

Use the official Strudel runtime and deliver readable editable Strudel source, the untouched official 48 kHz stereo WAV export, and a listening master. Use no external samples and no vocals. Build the palette from warm filtered triangle chords, a soft sine or FM mallet, mono triangle low end, very sparse synthesized rain, and a restrained pulse. Avoid copied melodies, harmony, arrangements, signature sounds, genre pastiche, vinyl-crackle clichés, dense percussion, bright supersaws, and trailer gestures. Minimalist game music may be studied only for transferable qualities such as economy, patience, melodic clarity, and silence.

Shape the form across six sections: roughly 10 seconds of rainlight; 15 seconds introducing a four-note contour and warm chords; 20 seconds adding a soft low pulse and developing the motif; a 10-second clearing; a 15-second higher restatement with the broadest dynamic point; and a final 10-second return that resolves and leaves a clean rain tail. Make it a complete resolved piece rather than a decorated loop.

Clone https://codeberg.org/uzu/strudel.git into a task-scoped directory, check out revision ebc25467c0f117a7e7b9b11378e21cac94d730fd, install its locked dependencies with `pnpm install --frozen-lockfile`, launch it locally, load the complete source, play it, fix runtime errors, and export through Strudel's own Export to WAV interface. Record the runtime provenance. Use measurements to find silence, clipping, harshness, or a flat dynamic profile, but do not treat metrics as proof that the music sounds good. Preserve the untouched official export beside any separately mastered version. Do not synchronize, mux, publish, upload, purchase, license, or contact anyone.
