Raga: Structure, Aroha-Avaroha, Vadi-Samvadi, and Prescribed Ragas
This domain tests whether you can describe a raga as a living melodic entity rather than a scale: its ascending and descending lines, its chief notes, its catch-phrase and its prescribed identity.
Core rules
- A raga is defined by its swara set, aroha, avaroha, vadi, samvadi, pakad, chalan and rasa or time association.
- Aroha is the ascending line; avaroha is descending. Either may be vakra (zigzag) or omit swaras (varjya).
- Vadi is the most important swara; samvadi is the second and is usually the fourth or fifth from vadi. Anuvadi are the remaining swaras; vivadi are avoided.
- Pakad is the identifying phrase; chalan is the characteristic movement. A correct scale with a wrong pakad is still a weak answer.
- Common prescribed ragas include Yaman, Bhairav, Bhairavi, Bilawal, Khamaj, Kafi, Asavari and Bageshri. Learn each with its altered swaras, vadi-samvadi and pakad.
Worked example
Compare Yaman and Bhairav. Yaman: S R G M^ P D N S; avaroha S N D P M^ G R S; vadi Ga, samvadi Ni; teevra Ma only. Bhairav: S r G M P d N S; avaroha S N d P M G r S; vadi Ma, samvadi Sa; komal Re and komal Dha. Reason in order: identify altered swaras, then vadi and samvadi, then check the aroha and avaroha lines. This prevents confusing the two ragas merely because both use Ma and Pa.
Traps
Do not call a raga a scale. Do not reverse aroha and avaroha. Do not place samvadi at random. Do not omit the pakad. Do not mix komal and teevra forms, and do not ignore a vakra movement.
