gospel-influenced ad-libs and runs between phrases)\n(Motif-Anatomy: The main hook, delivered with ultimate conviction and vocal freedom)\n(Phrase-Structure: 4-bar resolution with extensive vocal fills and ad-libs)\n(Contour-&-Range: Sustained high-register belting with virtuosic runs)\nReach the summit, taste the air\nLook around and no one's there\nAll that climbing, all that fire\nBurning through what I desired\nEvery anthem, every throne\nEvery ovation — I'm alone\nAll of it dissolves like smoke\nWhen there's no one left, no one left to hold\n\n[outro]\n(Transition: Band fades out, leaving just piano and intimate lead vocals)\n(Chords: Gmaj7 - Cmaj7 - Fmaj7 - Bbmaj7)\n(Mix: A long fade on the piano reverb tail; vocals are close-mic'd and breathy)\n(Inst: Piano plays gentle, arpeggiated chords, ending with a final virtuosic run)\n(Vocal-Perf: Intimate, improvisational ad-libs, mixing speech and song)\n(Motif-Anatomy: Deconstruction of the chorus melody into soulful fragments)\n(Phrase-Structure: Free-form phrasing, fading to silence)\n(Contour-&-Range: Descends from high-register ad-libs to a final, soft phrase)\nJust the echo of a life I built from marble and from stone\nBeautiful and cold\nAnd utterly alone",
