This study will research a modern design of acoustic guitar by analysis of the vibrational modes. The guitar that will undergo testing has been provided by Emerald Guitars and is solely constructed using Carbon Fiber Reinforced Plastic (CFRP). With the use of COMSOL Multiphysics© the soundboard of the guitar will be simulated and analysis will be carried out to determine the first 10 eigenfrequencies and the modal shapes these create. This paper will detail the preliminary results obtained using the physical data collected through experimental testing in a previous study. The paper will demonstrate an application of the finite element method in the field of musical acoustics.
