I wanted to analyze the phenomena that occur when an elastic, deformable structure interacts with fluid flow. Specifically, understanding how elastic deformation occurs in a flow and how elasticity can be tuned to control the outflow in a desired manner.
Consider, for instance, the lips of a trumpet player. A trumpet produces sound because the player’s lips vibrate in the space between the air pressure forced out from the lungs and the air pressure inside the cup leading to the instrument’s bore. And the way a trumpeter adjusts the ‘stiffness’ of their lips (i.e., embouchure) plays a crucial role in producing the desired sound.
Mastering the precise muscle control needed to produce the desired sound is extremely difficult, which is one reason why the barrier to entry for the trumpet is high. Learning to sing can be viewed in a similar light. The technique for controlling the vocal cords is something one has to master on one’s own. This demo was prepared to better illustrate that mechanism.
