Chicago musical style, 1920s jazz, big band, punchy brass stabs (trumpet, trombone, sax), driving swing rhythm, snare rimshots, cymbal crashes, vaudeville flair, dramatic dynamics, theatrical delivery. Energetic, bold, high-impact. 96–112 BPM, key of D minor. Include sharp brass accents on strong beats, glissandos on trombone, staccato string hits, walking bass pizzicato, piano with syncopated chords. Add percussive elements: shaker, cabasa, timbales for density. In the bridge: muted trumpet with melancholic line plus vibraphone shimmers and building crescendo. Final chorus: full tutti with crisp rimshot accents and crashing cymbals. Outro: dramatic brass stabs TU! TU! TU! then silence.
