  Indian twin drums mainly bayan and dayan (tabla) are the most important
percussion instruments in India popularly used for keeping rhythm. It is a twin
percussion/drum instrument of which the right hand drum is called dayan and the
left hand drum is called bayan. Tabla strokes are commonly called as `bol',
constitutes a series of syllables. In this study we have studied the timbre
characteristics of nine strokes from each of five different tablas. Timbre
parameters were calculated from LTAS of each stroke signals. Study of timbre
characteristics is one of the most important deterministic approach for
analyzing tabla and its stroke characteristics. Statistical correlations among
timbre parameters were measured and also through factor analysis we get to know
about the parameters of timbre analysis which are closely related. Tabla
strokes have unique harmonic and timbral characteristics at mid frequency range
and have no uniqueness at low frequency ranges.
