[global_style: Japanese sentimental slow piano ambient] [resolution_control: avoid full harmonic resolution, prefer suspended or ambiguous ending] [start with slow, elegant, ethereal solo piano introduction, strictly no other instruments, extremely soft dynamics (pp), wide spacing, long sustain, expressive rubato, low to mid register focus, simple and fragmented lyrical motif, strong sense of hesitation and silence between notes, like a fragile awakening of distant memory, intimate, lonely, and slightly cold atmosphere, avoid resolution] [Instruments: solo acoustic piano (felt piano or soft grand), no layers, no pads, no effects except very light natural reverb] . [Intro: sparse minimalist piano, very low note density, wide spacing, long sustain and natural decay, free tempo with unstable rubato, motif feels incomplete and slightly wandering, emphasizes silence as part of music, extremely soft and fragile, introspective and detached, no clear tonal resolution, evokes fading memory fragments] [Instruments: solo acoustic piano (soft grand or felt piano), extremely dry with subtle room reverb, no additional instruments] . . . [Build-up1: introduce very soft string pads (background only, low presence), maintain piano dominance, slightly increase harmonic continuity but keep ambiguity, motif repeats with micro-variations, rhythm becomes subtly more stable but still breathing, emotional tone restrained, like trying to recall something but not fully reaching it] [Instruments: acoustic piano (primary), very soft string pad (sustained, no attack, high-pass filtered), optional very light ambient texture (air/noise), no percussion] . . . [Drop: full piano expression with richer voicing but still soft-edged, strings expand into warm but blurred ensemble (no sharp attack), introduce canon-like overlapping phrases, emotional release appears but remains controlled and internalized, bittersweet and nostalgic peak, avoid dramatic contrast, keep flow continuous and immersive, no strong cadence] [Instruments: acoustic piano (full range), soft string ensemble (legato, layered violins/violas/cellos, no marcato), optional very soft sub bass pad (barely audible), no drums] . . . [Bridge: sudden reduction in density, remove most harmonic support, return to isolated piano notes and ambient resonance, introduce ambiguous or non-functional harmony, irregular timing, slight disorientation, suspended feeling, like losing direction or drifting in memory, emphasize unresolved tension] [Instruments: solo acoustic piano (sparse), ambient reverb tail, optional reversed piano texture or very subtle granular pad, no strings] . . . [Build-up2: gradual re-layering, strings become more defined but still soft and distant, introduce subtle counter-melody (not dominant), rhythm gains gentle forward motion, harmonic movement slightly more expressive (use add9, sus2, modal mixture), emotional weight increases but still restrained, avoid full release] [Instruments: acoustic piano (primary), soft string ensemble (slightly more presence), subtle secondary string line or piano counter-melody, optional light ambient pad, no percussion] . . . [Finale: highest density but maintain softness, piano and strings deeply intertwined, layered canon-like phrasing more prominent, expanded dynamic range (pp to mf only, never aggressive), strong sense of irreversible passage of time, emotional culmination feels like acceptance rather than explosion, lingering sadness dominates, avoid perfect resolution] [Instruments: acoustic piano (full expressive range), full soft string ensemble (rich but smooth), optional very low sub pad for depth, no percussion, no sharp transients] . . . [Outro: gradual dissolution, strings fade into airy reverb texture, piano returns to minimal fragmented motif, spacing widens again, tempo loosens, long decay and silence emphasized, unresolved cadence or suspended chord ending, leave empty, hollow, fading aftertaste, no closure] [Instruments: acoustic piano (very sparse), fading string pad (high frequency airy tail), reverb only, no new elements] . . .
