Ever since I started to learn about Raaga, the curiousity has been growing in me to understand why certain Raaga are used for "Happy situation" and why certain Raaga are used for "Pathos". What aspect of the Raaga makes us associate the Raaga with the emotions?
I made an attempt to understand the Raaga a bit deeper. I would like to share my attempt and the results with you.
Each raaga comprises of notes and each note represents a frequency. For the purpose of this experiment, I took 9 Raagas (Melakartha) and tried to plot the frequency that each Raaga represents and this is what I observed:
Without associating with the Raaga, imagine you were shown this graph in an analytical quiz session and asked to mark the odd ones out. What would be your choices of odd ones out? I would vote on "Subhapantuvarali", "Bhavapriya" and "Simmendramadhyamam" purely based on the pattern of the graph. And indeed, they are kinda odd ones because, they are the Raagas usually used in "Pathos".
If you are not convinced with me, I did another work on it. The Swarasthanam string for the above mentioned Raagas are:
HariKamboji: X0X0XX0X0XX0If you calculate the number of times "X"s come consecutively - 2 times, you can find that Bhavapriya, Subhapantuvarali and Simmendramadhyamam are the highest with the count as 3.
Also, if you calculate the number of times "X"s appear consecutively 3 times, again, only the above mentioned 3 Raagas have the count as 1 and rest all doesn't have any!!
I am sure, this observeration is not conclusive and needs more research, but, I am pretty much convinced that there is a scientific pattern associated with the Raagas and the emotions that they are associated with.
