Prescribed Ragas: Structure, Aroha-Avaroha, and Characteristic Phrases
What this domain tests
You must describe prescribed ragas through aroha, avaroha, pakad, vadi–samvadi, thaat, time, and characteristic phrases, then use those features to identify a raga from a short phrase. The exam prefers functional description over a bare scale.
How to describe a raga
- Give the aroha and avaroha, marking komal and tivra swaras.
- State the vadi and samvadi and the thaat.
- Give a pakad or chalan that shows movement, not just notes.
- Mention the time association and any special ornament or characteristic leap.
Worked example: Yaman
Aroha: Sa Re Ga Ma(tivra) Pa Dha Ni Sa. Avaroha: Sa Ni Dha Pa Ma(tivra) Ga Re Sa. Vadi Ga, samvadi Ni; thaat Kalyan; first prahar of night. Characteristic phrases include Ni Re Ga, Re Sa, and Pa Ma(tivra) Ga Re. The reasoning: tivra Ma and the Ga–Ni axis distinguish Yaman from Bilaval; the phrase Ni Re Ga shows the upper-Ni approach to Ga, which is more diagnostic than the plain scale. If a phrase uses shuddha Ma and no tivra Ma, do not label it Yaman without further evidence.
Worked example: Bhairav
Aroha: Sa komal Re Ga Ma Pa komal Dha Ni Sa; avaroha reverses it. Vadi Dha, samvadi Re; thaat Bhairav; morning. The slow oscillation on komal Re and komal Dha is central, so a phrase such as Ga Ma Pa komal Dha Pa, Ga Ma komal Re Sa signals Bhairav.
Traps
Do not write tivra Ma as ordinary Ma, place komal Re on the wrong note, or treat aroha as the pakad. Ragas sharing a thaat can differ by vadi, phrase, and ornament; mention those.
