Synopsis The semantic content of an art like music (sruti and layam) is multidimensional. Totality of perceptions (perhaps infinite) can actualise all the meaningful possibility implicit in a branch like ‘Layam’. ‘Layam’ in this context is treated as a sub-discipline of concert-music, devotional music, (congregations like bajans) drama and dance. The aim of the study is to clarify certain parameters of the art of percussion. Percussion-art had cultivated aesthetic principles which achieve fullness through correlation with other sub-divisions of the art of music.
