  "prompt": "Genre: Tropical House-Pop; BPM: 96; Key: C# minor; Rhythm: Mid-tempo, driving pocket syncopation with a dembow-lite feel, anchored by a four-on-the-floor kick and an interlocking percussive loop; Instruments: Dry close-miked marimba loop, percussive acoustic guitar strum, deep sub bass, layered hand snaps and claps, warm synth pads swelling underneath; Vocals: Male tenor, intimate close-mic delivery, shifting between rhythmic speech-singing and smooth melodic lines, with lush background vocal stacks for harmony; Mood: The feeling of a low-lit bar where the music is just right, and you lock eyes with someone across the room, a spark of instant, unspoken connection; Highlight: The instant, full-volume entrance of the syncopated marimba hook on beat one, with no instrumental preamble, immediately establishing the song's infectious groove",
  "title": "Salt and Signal",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Centered, punchy low-end. Dry, forward instrumental loops. Clean, spacious stereo field with minimal reverb.)\n(Inst: Looped marimba melody, percussive muted guitar strum, finger snaps.)\n(Hook-DNA: Syncopated 16th-note rhythmic motif repeats every bar; pitch centers on the root and fifth; hypnotic and immediate.)\n\n[verse]\n(Vocal-Perf: Intimate, close-miked, rhythmic speech-like delivery; low dynamic range.)\n(Inst: Kick drum enters (four-on-the-floor); marimba and guitar loops continue; sub bass enters on second half.)\n(Melody-Rhythm: Vocal phrases land just after the downbeat, weaving conversationally through the syncopated marimba.)\n(Chords: C#m - F#m - A - B)\nSomewhere between the second drink and the DJ switching tracks\nYou tilted your glass just slightly — I caught that\nThe condensation ring you left on the bar\nA small wet circle, a quiet little scar\n\n[pre-chorus]\n(Vocal-Perf: Shifts from rhythmic talk-singing to a more melodic, sung line; intensity builds.)\n(Inst: Percussion layers build with a subtle shaker and clap.)\n(Melody-Contour: Ascending stepwise line that creates tension leading into the chorus.)\n(Chords: C#m - F#m - A - B)\nNothing said, but something already moving\nThe whole room narrowed down to where you stood\nI felt the frequency before the sound\nLike static before lightning hits the ground\n\n[chorus]\n(Mix: Stereo image widens; vocal stacks panned for breadth.)\n(Vocal-Perf: Stronger, full-voiced melodic singing; features lush background vocal stacks.)\n(Hook-DNA: Core motif uses a memorable pentatonic shape; rhythm is a simple two eighths + quarter note pattern; pitch anchors on the 3rd; high repetition.)\n(Melody-Contour: Arch shape starting on the 5th, with a key m3 leap from the 3rd to the 5th.)\n(Melody-Rhythm: Vocal lands squarely on the beat, anchoring the groove.)\n(Melody-Harmonic-Tension: Melody sustains the major 7th over the V chord for two beats, creating a strong pull to resolve to the tonic i chord at the start of the next phrase.)\n(Chords: C#m - F#m - A - B)\nYou're the salt and signal in the air\nThat low hum pulling me somewhere\nBefore a word, before a stare\nAlready there, already there\nI don't know your name or where you're from\nBut every cell in me has come\nAlive — alive — with the pull of you\nYou're the salt and signal breaking through\n\n[verse]\n(Vocal-Perf: Returns to the intimate, rhythmic, close-miked delivery of the first verse.)\n(Inst: Arrangement drops back slightly to verse 1 texture, but kick and bass are maintained.)\n(Chords: C#m - F#m - A - B)\nThe bartender refills without being asked\nYou're laughing at something — I can't hear through the glass\nBut the laugh lines, the tilt of your head\nAre louder than anything anyone said\nA stranger two meters away feels close\nLike a song you forgot — the one you loved the most\n\n[bridge]\n(Vocal-Perf: Repetitive, chant-like call-and-response vocal layers.)\n(Inst: Texture thins to focus on a hypnotic vocal loop and minimal percussion.)\n(Melody-Harmonic-Tension: A simple two-note melody repeats over shifting chords, creating dissonance by not aligning with the harmony, holding a static, hypnotic tension before the final chorus release.)\n(Chords: C#m - F#m - A - B)\nFeel it, don't fight it, feel it\nFeel it, don't fight it, feel it\nFeel it, don't fight it, feel it\nFeel it, don't fight it, feel it\n\n[chorus]\n(Mix: Widest and fullest point of the track; ad-libs are layered in.)\n(Vocal-Perf: Highest energy performance; prominent ad-libs and harmonies.)\n(Inst: All instrumental and percussive layers are present.)\n(Hook-DNA: Core motif uses a memorable pentatonic shape; rhythm is a simple two eighths + quarter note pattern; pitch anchors on the 3rd; high repetition.)\n(Melody-Contour: Arch shape starting on the 5th, with a key m3 leap from the 3rd to the 5th.)\n(Melody-Rhythm: Vocal lands squarely on the beat, anchoring the groove.)\n(Melody-Harmonic-Tension: Melody sustains the major 7th over the V chord for two beats, creating a strong pull to resolve to the tonic i chord at the start of the next phrase.)\n(Chords: C#m - F#m - A - B)\nYou're the salt and signal in the air\nThat low hum pulling me somewhere\nBefore a word, before a stare\nAlready there, already there\nI don't know your name or where you're from\nBut every cell in me has come\nAlive — alive — with the pull of you\nYou're the salt and signal breaking through\n\n[outro]\n(Vocal-Perf: Layers of the main hook and the bridge chant weave together and fade.)\n(Inst: Strips back down to the core marimba loop and percussion before a gradual fade-out.)\nFeel it, don't fight it, feel it\nFeel it, don't fight it, feel it\nAlready there, already there\nYou're the salt and signal in the air",
