Abstract
The vocal ligament and the thyroarytenoid muscle are the vibrating elements that control fundamental frequency in singing. Their stress-strain relations are highly nonlinear. For a 3 octave f
o range, it requires an exponential rise in stress of the form eBε, where ε is the strain. The exponent B must be greater than 8.0 if there is a 2:1 vocal fold length change. There are also strong interaction nonlinearities. Maximum acoustic and aerodynamic power is transferred from the source to the airway if the glottal impedance approaches the airway impedance. The airway impedance can be controlled with the epilaryngeal airway, which acts like the mouthpiece of a trumpet.
