Which subject is not mentioned in Natyashastra ?

Question

Accepted Answer

The Natyashastra is an ancient Indian treatise on the performing arts, encompassing theatre, dance, and music. It is attributed to the sage Bharata Muni and is considered one of the foundational texts in Indian classical arts.

1. **Explanation for Option 1 (Rag):**
   - The term "Rag" refers to a melodic framework in Indian classical music. While the Natyashastra does discuss music, it primarily focuses on the theatrical aspects, including drama and dance. The detailed exploration of ragas as understood in the context of Indian classical music developed later, particularly in texts like the Sangita Ratnakara. Therefore, "Rag" as a subject in the detailed musical sense is not explicitly mentioned in the Natyashastra, making Option 1 the correct answer.

2. **Explanation for Option 2 (Sarna):**
   - "Sarna" is not a term commonly associated with the Natyashastra or Indian classical arts. However, since the task is to justify why Option 1 is correct, it is important to note that the absence of "Sarna" in the context of the Natyashastra does not affect the correctness of Option 1. The focus remains on the fact that "Rag" as a detailed subject is not mentioned.

3. **Explanation for Option 3 (Kutup):**
   - "Kutup" is not a recognized term within the context of the Natyashastra or Indian classical arts. Its mention here does not relate to the core subjects discussed in the Natyashastra. Therefore, it does not impact the correctness of Option 1 being the right answer.

4. **Explanation for Option 4 (Shruti):**
   - "Shruti" refers to the smallest gradation of pitch that the human ear can detect and is a fundamental concept in Indian music theory. The Natyashastra does mention "Shruti" in the context of musical notes and scales, as it lays the groundwork for understanding sound and music in performance arts. This makes Option 4 incorrect in the context of the question.

In conclusion, while the Natyashastra covers a wide range of topics related to performing arts, the specific and detailed concept of "Rag" as it is understood in later musical texts is not mentioned, making Option 1 the correct answer.
