According to the Time theory, which 'Thaats Raga' are sung in the 'Pratham Prahar' of Day and Night ?

Question

Accepted Answer

Option 1, which includes the 'Thaats Raga' Bilawal and Kalyan, is the correct answer for the ragas sung in the 'Pratham Prahar' of Day and Night according to the Time theory in Indian classical music. Here's a detailed explanation:

1. **Explanation for Option 1 (Bilawal, Kalyan):**
   - **Bilawal Thaat:** This is one of the ten basic thaats in Hindustani classical music. Ragas derived from Bilawal Thaat are typically sung in the morning, aligning with the 'Pratham Prahar' of the day. The serene and calm nature of Bilawal makes it suitable for the early hours, setting a peaceful tone for the day.
   - **Kalyan Thaat:** Similar to Bilawal, Kalyan is another major thaat that includes ragas often performed in the evening, which corresponds to the 'Pratham Prahar' of the night. The uplifting and auspicious nature of Kalyan ragas makes them ideal for the beginning of the night.

2. **Explanation for why other options are incorrect:**
   - **Option 2 (Kafi, Asawari):** Kafi and Asawari thaats are generally associated with the late evening and night. Ragas from these thaats are not typically sung in the 'Pratham Prahar' of the day or night, as their mood and structure are more suited to later hours.
   - **Option 3 (Bhairav, Bhairvi):** Bhairav thaat is traditionally performed in the early morning, but Bhairvi is more flexible and can be sung at any time, often associated with the end of a performance. Therefore, this combination does not fit the specific 'Pratham Prahar' of both day and night.
   - **Option 4 (Marva, Purvi):** Marva and Purvi thaats are usually linked with the late afternoon and early evening. Their intense and serious nature does not align with the freshness and tranquility desired in the 'Pratham Prahar' of the day or the welcoming nature of the night.

In conclusion, Option 1 is correct because Bilawal and Kalyan thaats are perfectly aligned with the 'Pratham Prahar' of day and night, providing the appropriate mood and atmosphere for these times.
