13.How is a thala different from rhythm?
Carnatic music has one of the most complex thala systems among the world's music systems. Both in terms of the mathematical ranges and rhythmic varieties or thalams used, Carnatic music has no parallel.
Tala is bascially a time-measure and it is executed in cyclical pattern. concept. Therefore, it has a beginning and an end and is repeated until the composition ends.
When a tala cycle is sub-divided into units of time - e.g. 4, 8, 6, 16, 9 etc. - various thalams are produced.
In Carnatic music, the complex structure of the thala system has contributed to the development of rhythm and to the art of percussion.
Because of the thala strucutres, the role of a percussionist in Carnatic music (e.g. mridangam player) is far more intense and demanding than in any other system of music. The percussionist in the Carnatic music system does not merely keep time and provide the basic sarva laghu (four-beats). The percusionist must go beyond time-keeping and must judiciously and dexterously bring out the mood and emotion of a composition. Therefore, the percussionist would play a variety of mathematically-timed rhythmic patterns. This requires that the percussionist undergo significant training not only in producing various rhythmic patterns but also in developing musical acumen to know when a certain rhythmic pattern will be appropriate.
