Step 1: Concept
Ubhaya vakra raga is a specific type of raga characterized by its unique structure, which includes both ascending (Arohana) and descending (Avarohana) patterns that are not symmetrical. This means the notes followed when going up from the tonic are different from those used when coming down.
Step 2: Meaning
The term "Ubhaya vakra" translates to "both crooked," indicating a raga with an asymmetrical scale structure in both ascending and descending directions.
Step 3: Analysis
Let's examine each option:
Dhanyasi: This raga is known for its symmetrical ascent and descent, making it不符合ubhaya vakra的定义。
Kambhoji: It has a unique structure where the ascent and descent are not identical. The ascent (Arohana) includes all seven notes of the scale, while the descent (Avarohana) does not follow this pattern exactly, fitting the description of ubhaya vakra.
Poornachandrika: This raga is known for its symmetrical structure in both ascending and descending scales, thus it不符合ubhaya vakra的定义。
Kaanada: It also follows a symmetrical scale structure, making it不符合ubhaya vakra的定义。
Step 4: Conclusion
Based on the analysis, Kambhoji (选项B) is the raga that has an asymmetrical ascending and descending pattern, fitting the definition of ubhaya vakra.
Final Answer: (B)
