​"Long instrumental track (4 minutes). Start with a melancholic solo acoustic guitar playing a slow arpeggio in a minor key, strictly following the 3/4 folk waltz rhythm of 'Mi Querido Viejo'. At 0:30, transition the rhythm into a 4/4 R&B slow jam but keep the same guitar melody as the main hook. [Structure: Folk Intro, R&B Verse, Lush Chorus with strings, Verse, Climax Chorus, Outro]. Emotional, cinematic, nostalgic, warm analog sound. Instrumental only."
