Transition points in vocal registers are called what?

• A. Dialogo
• B. Timbre
• C. Balance
• D. Passagio

Answer: (D)

Passaggio explains the moment where a singer’s voice shifts from one register to another, typically from chest voice to head voice. This zone marks a change in how the vocal folds vibrate and how resonance is produced, which is why it often feels like a small break if not blended smoothly. Understanding how to navigate the passaggio—using breath support, coordinated laryngeal effort, and careful vowel shaping—lets a singer glide through those notes with a connected, even tone. This term is specifically about the transition between registers, whereas timbre is about overall tone color, balance refers to evenness across the range rather than a boundary, and dialogo isn’t the standard term for this phenomenon.
