The vocal mechanism is described by which phrase that lists its components of air supply, vibrator, and resonator?

• A. Three main vocal parts involved in creating sound
• B. Air supply (diaphragm), vibrator (larynx), resonator (pharynx and mouth cavity)
• C. Performance competencies for Pre-K
• D. Core Repertoire List

Answer: (B)

The vocal mechanism is described as three interconnected parts: air supply, vibrator, and resonator. This framing follows the flow from breath to sound to its shaping. The air supply comes from the diaphragm and lungs, providing the energy that moves the air through the vocal tract. The vibrator is the larynx and its vocal folds, which vibrate as air passes, creating sound. The resonator includes the pharynx, mouth, and other cavities that color and project the sound, giving tone and character. Because this phrase directly names those three functional components in order, it cleanly captures how voice is produced and shaped, making it the best fit. The other options either describe things too vaguely or introduce unrelated topics like performance competencies or repertoire lists, which don’t describe the mechanism of sound production.
