Modeling and testing of the musical instrument string motion
Krešimir Lanc, Sanjin Braut, Roberto Žigulić · 2014
This paper considers testing of the musical instrument string motion. First, a mathematical model for an idealized string motion was presented. Simulation results of string tension, mass per unit length and string length influence on a fundamental tone of string vibration were compared to measurement results performed on Fender Stratocaster electric guitar. Furthermore amplitude distribution of string motion considering position of plucking is analyzed. Simulation results of amplitude distribution are performed using Fourier series with taking into account plucking position as an initial condition. These results are compared with frequency spectra obtained from measurements of two different types of guitar i.e. acoustic guitar with steel strings and classic guitar with plastic string.
