Which vocal technique involves rapid switching between normal and falsetto voices, used by Gene Autry and Jimmie Rodgers?

• A. Yodeling
• B. Falsetto
• C. Scat singing
• D. Sprechstimme

Answer: (A)

Rapid switching between normal chest voice and a high falsetto creates the distinctive yodeling sound. In yodeling, a singer quickly flips from a full, natural tone to a light, high falsetto and back again, producing the characteristic whistle-like effect. Gene Autry and Jimmie Rodgers helped popularize this technique in country music, using those rapid register changes to add a playful, register-breaking flair to their songs. Falsetto alone is just the high voice without the quick back-and-forth, scat singing is jazz-improvised syllables, and Sprechstimme blends speech with pitch in a different musical context. So the described technique is yodeling.
