Step 1: Concept Identification: The inquiry seeks to determine which of the listed Tabla Gharanas are recognized for their 'Khula Baaj' (open playing technique).
Step 2: Explanation:
- (A) Farukhabad, (B) Lucknow, (C) Banaras: These Gharanas, collectively known as 'Purbi' (Eastern), are foremost practitioners of the Khula Baaj, which accentuates open-handed, resonant strikes.
- (D) Punjab: The Punjab Gharana, while possessing its own unique style, is significantly influenced by the Pakhawaj and features forceful, open strokes. Consequently, it is also categorized as a Khula Baaj gharana, differentiating it from the more closed styles of Delhi and Ajarada.
As all four mentioned Gharanas predominantly employ an open playing style, each can be classified under 'Khula Baaj'.
Step 3: Conclusion:
Farukhabad, Lucknow, Banaras, and Punjab are all Tabla Gharanas associated with the Khula Baaj.
