  Abstract: This undergraduate research project focuses on a full size acoustic cello, and investigates the correlation of the resonance properties between the strings and wooden body. The goals are to investigate the radiation patterns of the produced sound waves, to take high-speed video of a played string to physically observe the standing wave, and to simulate the body resonance of the cello. A mathematical model is formed to approach the situation where a musician plucks a string. Typical approaches assume the surface area of a finger to be a point source, but the surface area is actually parabolic, forming a bend in the string that is continuous to the following straight line. These same methods will be applied in an anechoic chamber to test ideal conditions. Results of this research can be used to teach waves and resonances.
