``` Cinematic tango, slow 65 BPM, D minor. Classic tango rhythm: strong accent on 2nd beat. Weeping bandoneon leads, cello and double bass for sorrow, piano with marcato chords. Female vocal: whispered pain in verses, fierce defiant belt in chorus. Bridge: voice + piano only, then full orchestra with brass, timpani, choir. Noir film finale. Triumphant, resilient. ```
