Your Voice: An Inside View Ch 3: Resonance
- What are the two fundamental types of resonance that occur in the human body?
- Free resonance and forced/sympathetic resonance.
- Why are the chest and head not good resonators for the projection of sound?
- They are only perceived by the singer; they can feel the vibrations in their body, but it doesn’t do anything to amplify the sound. They’re covered in muscle/flesh to dampen the sound.
- What are the four traits common to all musical instruments, including the voice
- Power/energy source, vibrator, resonator, articulator.
- Why is the vocal tract considered to be a quarter-wave resonator?
- Because it has a closed end and an open end for sound to escape. “Frequencies with a quarter-wavelength equal to the length of the vocal tract are the first to be resonated.”
- What is the relationship between the harmonic series and the resonance series of a quarter-wave system?
- Resonance series only have odd-numbered harmonics (i.e. 1/4, 3/4, 5/4, 7/4)
- Define musical resonance.
- The intensification and enriching of a musical tone by supplementary vibration.
- What anatomical structures function as free resonators in the human voice?
- Laryngopharynx, orpharynx, nasopharynx, nasal cavity, oral cavity, and trachea.
