What improvisational technique did Armstrong use in Heebie Jeebies?

• A. Scat singing
• B. Scales running
• C. Muted trumpet
• D. Call and response

Answer: (A)

Scat singing, a vocal improvisation using playful syllables instead of words, is the technique on display. In Heebie Jeebies, Armstrong forgot the lyrics and immediately filled the space with improvised syllables that fit the melody and rhythm, turning his voice into an instrument. This moment helped popularize scat singing in jazz because it shows how a vocalist can create melodic ideas in real time, responding to the tempo and soloist’s ideas just as a horn would. The other options don’t capture what happened here. Scales running refers to practicing or presenting scalar patterns rather than an improvised vocal technique. A muted trumpet is a horn effect Armstrong often used in performance, but the memorable feature of this recording is the voice-driven improvisation. Call and response is a broader ensemble interaction technique and not the specific improvised vocal approach Armstrong demonstrated in this moment.
