The Anthem of Vaudeville Jazz
Written by Kander and Ebb, "All That Jazz" is the opening number of the musical Chicago. Catherine Zeta-Jones' rendition for the 2002 film is widely considered the gold standard for modern altos. It captures the essence of the character Velma Kelly: gritty, breathless, and commanding.
To sing this correctly, you must treat your voice like a jazz instrument. It requires slides, purposeful vocal fry, and impeccable timing. The challenge isn't the range—it's the style.
Phase 1: The Breathy Intro (0:00 - 1:15)
The song starts low and sultry. The phrase "Why don't we paint the town?" sits in the lower register (F3-A3). The goal here is intimacy. You are inviting the listener into a secret.
The Trap: Dropping the energy. Even though it is quiet, your core must be engaged. Use a "vocal fry" onset on words like "Jazz" or "Knees" to add that signature Velma Kelly growl.
Phase 2: The Storytelling (1:15 - 3:40)
As the tempo picks up, diction becomes king. Lines like "Slick your hair and wear your buckle shoes" need to be spat out with rhythmic precision.
- Consonants: Over-enunciate the 'K's and 'T's. This is musical theatre; the audience needs to hear every word over the brass section.
- Placement: Move your resonance forward into the "mask" (the front of your face) to get that bright, brassy sound without straining your throat.
Phase 3: The Big Finish (3:40 - End)
The finale requires a transition from the conversational tone to a full theatrical belt. The final sustained "And all that JAZZ" climbs to a D5.
To nail this, drop your jaw and think of the vowel as an "Ah" rather than a tight "Aa". Keep the larynx neutral. If you raise your chin to reach the note, you will cut off your air supply. Anchor your feet and drive from the diaphragm.
