Input: [header] How to yodel [title] Identify the break between the chest and upper registers. [step] Yodeling requires you to switch between your chest register (normal voice) and upper register (falsetto). Where normal voice transitions to falsetto, there will be a break or voiceless gap in your tone. <sep> (A) You can identify a pause in the conversation. Switch between these two volumes, and figure out whether you will need to hum to achieve the spoken falsetto. (B) You'll have to vocally jump back-and-forth across this break when yodeling. [substeps] Your normal voice will vibrate your chest and have a mellow sound. (C) Think about what type of voice you have, what tone, and when. Thus, you might block out certain vowel sounds using the inside register (falsetto), which are the lower registers of your voice. (D) Your falsetto is the higher register, and gives you a distinctive tone. [substeps] Falsetto refers to a slow or slowing stutter-phrase.
Output:
B
