a) What are the two fundamental types of resonance that occur in the human body? Free Resonance and Forced Resonance
b) Why are the chest and head not good resonators for the projection of sound? They are covered with muscle and fat that dampen vibrations.
c) What are the four traits common to all musical instruments, including the voice? A power source, a vibrator, a resonator, an articulator
d) Why is the vocal tract considered to be a quarter-wave resonator? It is a closed/open tube; frequencies with a quarter-wavelength equal to the length of the vocal tract are the first to be resonated
e) What is the relationship between the harmonic series and the resonance series of a quarter-wave system? The resonance series contains only the odd-numbered harmonics.
f) Define musical resonance. The intensification and enriching of a musical tone by supplementary vibration
g) What anatomical structures function as free resonators in the human voice? the trachea, laryngopharynx, oropharynx, oral cavity, nasopharynx, and nasal cavity
