The Sound Characteristics Of The Baglama With Respect To Different Chest Shapes

Abstract

Baglama is the most common folk string instrument in Turkey. It has a bowl-shaped resonator box called a chest which amplifies the sound. The chest can be constructed in various forms by the luthiers. This study aims to determine the sound characteristics of the baglama associated with different chest forms. First, a prototypical baglama was modeled and analyzed numerically with the SolidWorks, HyperMesh and Actran software programs. Operational Deflection Shape (ODS) measurements of the baglama were also carried out experimentally. The numerical results were compared with the experimental ones and had an excellent agreement. Using this experimentally validated numerical model, the natural frequencies, mode shapes and sound propagation properties of the baglama were investigated for chests of different geometries.
