The distinct rhythmic variations in Indian music are characterized by Layakari, the skill of introducing polyrhythms within a fixed tempo. When executed by a singer or melodic instrumentalist, the variations in different tempos and rhythms concerning a standardized tempo and rhythm are termed Layakārī, while an accompanist ensures the maintenance of the standard. These variations are presented in contrast to the regularity maintained by the percussionist, serving as embellishments to the Laya.

There are five types of Layakārī:

1. Catasra: When the basic Laya is divided into equal portions, it is known as Catasra Layakārī. For instance, a Tāla of sixteen Mātrā divided into four groups of four beats each.

2. Tisra: In a Tāla of sixteen Mātrā, the variation is executed in a way that each interval is one-fourth less in value than the standard one. It is equivalent to Āḍi.

3. Khaṇḍa: In a Tāla of sixteen Mātrās, the variation occurs with each interval being one-quarter greater in value than the standard one, lasting 1 and ¼ beats.

4. Miśra: The interval of the variation in Miśra has the value of 1 and ¾ compared to the standard one.

5. Saṁkīrṇa: In Saṁkīrṇa, the interval of the variation has the value of 2 and ¼ compared to the standard one.

An alternative interpretation of the first four categories is as follows:

1. Catusra: Tāla composed in groups of four Mātrā each.

2. Tisra: Tāla composed in groups of three Mātrā each.

3. Khaṇḍa: Tāla composed in groups of an unequal number of Mātrā.

4. Miśra: Tāla composed of both groups of four and three Mātrā.
