  "prompt": "Genre: Dark Pop; BPM: 89; Key: Am; Rhythm: Steady pop backbeat in verses, transitioning to a trap-influenced 16th-note hi-hat groove in the chorus; Instruments: Pizzicato string ostinato (Hook), deep sub-bass synth (Foundation), clean electronic drum kit (Groove), melancholic piano synth (Chords), atmospheric synth pads (Texture); Vocals: Male tenor with a breathy, intimate verse delivery that builds to an emotional, strained chest voice in the chorus, supported by layered falsetto harmonies; Mood: Melancholic and dramatic, with a sense of romantic fatalism and introspection; Production: Polished modern pop with a wide stereo image, deep sub-bass, and clear, centered vocals, using reverb for atmospheric space; Structure: Intro - Verse - Pre-Chorus - Chorus - Verse - Bridge - Chorus - Outro; Language: English; Highlight: the recurring pizzicato string motif that creates a sense of dramatic tension",

  "lyrics": "[intro]\n(Chords: Am - Fmaj7)\n(Inst: Staccato pizzicato strings, distant piano chords, subtle sub-bass)\n(Mix: Centered strings, wide atmospheric space, anticipation)\n(Vocal-Perf: None)\n\n[verse]\n(Chords: Am - Am - Fmaj7 - Fmaj7)\n(Vocal-Perf: Breathy, close-mic delivery, low dynamic range, hint of vocal fry)\n(Melody-Contour: Mostly conversational, stepwise motion, stays in a narrow lower range)\n(Melody-Rhythm: Phrases starting on the downbeat, relaxed and slightly behind the beat)\n(Inst: Simple kick-snare pattern enters, pizzicato strings continue, piano holds chords)\n(Mix: Vocals are intimate and dry, centered. Instruments remain in the background)\n(Transition: A subtle reverse cymbal swell builds into the pre-chorus)\nThe mirror on the wall\nShows someone I don't recognize\nI built this careful mask\nPretending I was doing fine\nEvery word I say\nFades before it lands\nI'm fluent in the silence\nOf a stranger's hands\n\n[pre-chorus]\n(Chords: G - Am)\n(Vocal-Perf: Dynamics increase slightly, more air and intensity in the voice)\n(Melody-Contour: Ascending line, building tension towards the chorus)\n(Inst: Drums become more prominent, bassline becomes more active)\n(Mix: Vocal widens slightly with a short delay throw)\n(Sound-Design: Filter sweep on the drums, creating a sense of lift)\nI dressed my wounds in reasons\nAnd called it healing\n\n[chorus]\n(Chords: C - G - Am - F)\n(Hook-DNA: The main hook is a descending melodic phrase on the title line, repeated with slight variation. Its catchiness comes from the rhythmic syncopation against the straight beat and the emotional leap into a higher vocal register on the first word.)\n(Vocal-Perf: Full chest voice, emotional strain, layered with high falsetto harmonies and background vocal responses like \"Deceiving, Believe it\")\n(Melody-Contour: Starts high and descends, creating a feeling of resignation. Peaking on the first note of each main phrase)\n(Melody-Rhythm: Syncopated, punchy phrasing that contrasts with the smoother verse melody)\n(Inst: Full beat with 16th-note hi-hats, powerful sub-bass, atmospheric synth pads, pizzicato strings continue)\n(Mix: Wide and powerful. Sub-bass dominates the low end, vocals are layered and sit on top, surrounded by wide harmonies and synths)\n(Transition: Beat drops out for a moment, leaving just a sustained chord and vocal echo)\nI'm fading\nStill waiting\nFor someone to pull me out\nI'm breaking\nNot making\nA sound behind the doubt\nI built a glass alibi\nSo pretty\nSo brittle\nOne touch and it shatters wide\nEvery hollow bone inside me\nWonders how I've stayed alive\nI'm living a glass alibi\n\n[verse]\n(Chords: Am - Am - Fmaj7 - Fmaj7)\n(Vocal-Perf: Returns to the intimate, breathy delivery of the first verse, maintaining a conspiratorial tone)\n(Melody-Contour: Similar conversational contour to verse 1, but with slightly more rhythmic variation)\n(Inst: Beat simplifies back to the verse pattern, but a new subtle synth arpeggio is added for texture)\n(Mix: Intimate mix returns, but with the added synth element creating a bit more movement in the stereo field)\n(Transition: Gradual crescendo in the synth pad and a drum fill leads into the bridge)\nI answer every call\nWith a version trained to smile\nI've memorized the script\nOf someone living in denial\nAnd when the lights go out\nAnd the room goes cold\nI count the cracks in ceilings\nLike a secret I was told\n\n[bridge]\n(Chords: F - C - G - Am)\n(Vocal-Perf: More rhythmic, almost chanted delivery. Vocals are processed with a filter or phaser effect, building intensity)\n(Melody-Contour: A repetitive, stepwise melodic pattern that builds tension through repetition rather than melodic leaps)\n(Inst: Drums build in intensity, using tom fills. The bassline becomes more melodic and driving. Main piano is replaced by a filtered synth)\n(Mix: The mix becomes denser and more compressed, feeling like it's rising towards a peak)\n(Sound-Design: A low-pass filter opens up dramatically into the final chorus, creating a huge drop)\nNo one sees the weight\nNo one reads the page\nSmiling through the static\nThat I can't explain\n\n[chorus]\n(Chords: C - G - Am - F)\n(Hook-DNA: The main hook is a descending melodic phrase on the title line, repeated with slight variation. Its catchiness comes from the rhythmic syncopation against the straight beat and the emotional leap into a higher vocal register on the first word.)\n(Vocal-Perf: Maximum emotional intensity. Ad-libs and higher harmonies are added. The lead vocal is powerful and soaring)\n(Inst: All elements are present and at their loudest. Sustained strings are added for more drama. Drums are punchy and driving)\n(Mix: The biggest and widest point of the song. The sub-bass is huge, and the vocal layers fill the entire stereo spectrum)\n(Transition: Abrupt cut at the end, leading into a quiet outro)\nI'm fading\nStill waiting\nFor someone to pull me out\nI'm breaking\nNot making\nA sound behind the doubt\nI built a glass alibi\nSo pretty\nSo brittle\nOne touch and it shatters wide\nEvery hollow bone inside me\nWonders how I've stayed alive\nI'm living a glass alibi\n\n[outro]\n(Chords: Am - Fmaj7)\n(Vocal-Perf: A single, melancholic ad-lib of the title phrase, fading out with heavy reverb and delay)\n(Inst: Just the original pizzicato string motif and a fading piano chord)\n(Mix: Decays quickly, leaving a long reverb tail on the final vocal and piano. Very sparse and atmospheric)\n(Structure: Fades to silence)\nA glass alibi",
