Show Solution

The Correct Option is B

Solution and Explanation

Step 1: Concept Identification:
The query pertains to 'Moorchana' in ancient Indian musicology and seeks the count mentioned in historical texts.
Step 2: Elaboration:
A Moorchana is a specific arrangement of notes within a 'Grama' (parent scale), initiated from each of its seven notes. Ancient Indian music recognizes three Gramas:
1. Shadja Grama
2. Madhyama Grama
3. Gandhara Grama (historically noted but not currently in practice)
Each of these heptatonic Gramas generates 7 Moorchhanas.
Consequently, the aggregate number of Moorchhanas is 7 (from Shadja Grama) + 7 (from Madhyama Grama) + 7 (from Gandhara Grama), totaling 21.
Step 3: Conclusion:
Ancient musicological texts document a total of twenty-one Moorchhanas.
