摘要

The richness of the sound emanating from a stringed musical instrument can be improved by the making it linger for longer. This has traditionally been performed in sitar and sarod by modification of boundary conditions while introducing a jawari. We try to understand the effect of the jawari by assuming periodic modulation of boundary conditions of the string in a sonometer and find that the lobe-like effect can indeed be observed as an interference between the frequency-modulated sideband of one mode with the next higher-order mode. The contributions from different modes can be added up. The size of the beat signal increases while increasing the depth of modulation.
