This is the fourth volume of the series, "The Complete Reference for Tabla". This entire book is devoted to the compositional form known as the Kaida. This is the most important approach to theme-and-variation for the tabla. It covers kaidas according to their origin (e.g., Dilli kaidas) and by their style (e.g., Kaida rela). There are numerous examples and a special index to allow one to find a kaida that may be of interest.
