Raga Theory and Lakshana
What the exam tests
Raga Theory and Lakshana tests whether you can describe a raga as a living melodic system, not a scale.
Core rules
- Aroha and avaroha give ascent and descent; they may be vakra and may omit notes. Jati counts notes in each direction: audav 5, shadav 6, sampurna 7; mixed jati is written as audav-sampurna and so on.
- Pakad is the identifying catch-phrase; chalan is the wider movement grammar. Vadi is the main note, samvadi the next supporting note, anuvadi are other used notes, vivadi is avoided or used only in a special phrase.
- Time of day is a traditional lakshana, not a rule of acoustics; it is preserved in concert practice and should be given as a prahar where possible.
Worked example
Yaman: aroha S R G M^ P D N S; avaroha S N D P M^ G R S; vadi Ga, samvadi Ni; samay first prahar of evening. A pakad such as Re Ga Ma^ Pa, Ma^ Ga Re Sa shows the tivra Ma and the Ga-Ni axis. If an answer says Yaman has komal Ma, the scale description is wrong even if the phrase sounds close.
Traps
Do not confuse vadi with samvadi, or pakad with full chalan. Do not assume every raga is sampurna. Do not label vivadi as forbidden in all contexts. Time answers should use prahar, not clock time only.
