Improving accuracy in parametric reduced-order models for classical guitars through data-driven discrepancy modeling Open
Recently developed high-fidelity finite element (FE) models represent a state-of-the-art approach for gaining a deeper understanding of the vibrational behavior of musical instruments. They can also be used as virtual prototypes. However, …

Port-Hamiltonian fluid–structure interaction modelling and structure-preserving model order reduction of a classical guitar Open
A fluid–structure interaction model in a port-Hamiltonian representation is derived for a classical guitar. After discretization, we combine the laws of continuum mechanics for solids and fluids within a unified port-Hamiltonian (pH) model…

Model-predicted geometry variations to compensate material variability in the design of classical guitars Open
Musical instrument making is often considered a mysterious form of art, its secrets still escaping scientific quantification. There is not yet a formula to make a good instrument, so historical examples are regarded as the pinnacle of the …

Examination of polarization coupling in a plucked musical instrument string via experiments and simulations Open
In this article, the transient motion of a realistically plucked guitar string is studied experimentally and numerically in both transversal polarizations. The frequency dependent damping and suitable initial conditions are identified in t…
