Concept:
The technical classification of Tabla playing styles distinguishes between Band Baaj (closed-finger style, which focuses on crisp, muted syllables) and Khula Baaj (open style, which utilizes resonant palm strokes derived from the Pakhawaj).
Step 1: Analyze Assertion (A).
Assertion (A) states that the structural composition known as Kayda belongs to the Band Baaj classification. A Kayda is characterized by its strict finger placement rules, precise stroke execution, and clear, rapid articulation, all of which are defining elements of the closed-finger style (Band Baaj). Therefore, Assertion (A) is true.
Step 2: Analyze Reason (R) and evaluate the connection.
Reason (R) states that the Kayda form is primarily utilized in the Delhi and Ajrada Gharanas. Historically, the Delhi Gharana pioneered the closed finger style (Band Baaj or Kinaar ka Baaj), using crisp stroke patterns on the edge of the drum, and created the Kayda system to expand their themes logically. The Ajrada Gharana later expanded on this style.
Because the Kayda is a core feature of the Delhi and Ajrada repertoires, and these gharanas are the historical architects of the closed-finger style (Band Baaj), the reason directly explains why the Kayda is classified under the Band Baaj style. Thus, both statements are correct, and (R) is the correct explanation of (A).
