Abstract

This contribution deals with the discussion and definition of optimization parameters of the lowest natural frequencies of an acoustic guitar from the geometric characteristics of the top integrated to their internal bracings. Thus, comparative modal analysis of the top (by using Finite Element Method) was performed to identify the sensitivity to these parameters on the typical lowest frequencies of a guitar. The results provide a primary guideline to beginners’ luthiers when tailor manufacturing a customized guitar.
