A complete original 60-second cue with a short opening and a naturally resolved quiet ending before 60 seconds.\nVocal Details: Strictly instrumental. Rhodes electric piano carries lyrical short melodies. No voice, singing, humming, speech, scat or vocal samples.\nArrangement: Start with a spacious Rhodes ninth-chord voicing. Round pizzicato upright bass and quiet brushed snare enter underneath; cymbals remain delicate. Leave a breath after each piano phrase and let the bass answer sparingly. Develop the opening motif with subtle rhythmic variation. No vinyl crackle or exaggerated reverb. During the final ten seconds the brushes recede, bass approaches the tonic and the piano resolves with a short natural decay.\nCollection variation: A soft acoustic piano begins with a spacious upper-register motif; let upright bass answer in the lower register.",
