Step 1: Concept
This question relates to the structural terminology used in Carnatic musicology, specifically in the performance of Ragam-Tanam-Pallavi (RTP) and the composition of the Pallavi line.
Step 2: Defining Arudi
In a Pallavi composition, the lyric line is divided into two parts: the Purvanga (first half) and the Uttaranga (second half). The precise point of transition where the first half ends in a sustained, majestic pause before the second half begins is called the Arudi.
Step 3: Synonymous Music Terminology
- In traditional treatises, the structural mid-point of the composition where this restful landing occurs is referred to as the Padgarbham (or Padagarbha), literally meaning the "womb or core of the song line".
- Pharan, Korvai, and Mohra are technical rhythmic segments played on percussion instruments, not structural pause points of a melody line.
Step 4: Conclusion
Hence, the other name for Arudi is Padgarbham, matching option (B).
Final Answer: (B)
