    "text": "Global Metadata: Instrumental minimal ambient electronica for a quiet work session, steady 80 BPM, consistent low energy, restrained treble and intimate clear stereo production. A complete original 60-second cue with a short introduction and a quiet resolved ending before 60 seconds.\nVocal Details: Strictly instrumental. A muted electric-piano ostinato carries the small recurring motif. No vocals, speech, humming, choir or vocal samples.\nArrangement: Fade in a soft rounded synthesizer pad, then introduce a muted four-note electric-piano ostinato, smooth low bass pulse and very quiet closed hi-hat. Move harmony slowly while making tiny timbral changes, with no new foreground melody. Avoid drum fills, risers, drops and abrupt breaks. During the final ten seconds soften the pulse, settle on the home harmony and allow the pad to decay calmly.\nCollection variation: Use a new gently repeating four-note bell-like Rhodes pattern with rolled-off treble and a very soft bass pulse.",
