Alright. In our last post about the roots of music, we paid our tributes to the "Sangeetha Mummoorthigal".
We all know that the building blocks of music lies in the 7 swaras. It is believed that originally the hymns in the praise of God were sung in 3 notes and it later evolved into 7 notes. They are:
Sa - Shadjam - Giving Birth
Ri - Rishabam - Morality
Ga - Gaandharam - Fragrant/Light
Ma - Madhyamam - Middle
Pa - Panchamam - Fifth
Da - Dhaivatam - Of Gods
Ni - Nishaadam - Sit/Lie down
On the other hand, references to 7 swaras is believed to be found in Silapathikaaram. And according to Tamil literature, the 7 swaras are:
kural = C (sa)
thutham = D (ri)
kaikilai = E (ga)
uzhai = F (ma)
iLi = G (pa)
viLari = A (da)
tharam = B (ni)
Even references to scale, grahabedham etc. are believed to be found in the works of Elango Adigal. Let us keep the debate of Sama Veda vs Silapathikaaram aside and move on to what a scale means. Once we learn alphabets (A-Z), don't we try and form words & sentences to convey our emotions? The same way, these alphabets of music (7 Swaras) can be combined to form melody.
Scale is a group of the notes in ascending and descending order that forms melody. Didn't we hear that Raaga is also group of certain notes in ascending and descending order? So, is Raaga same as scale? Look at the two pictures. Do you find any difference between them?
Obvious, isn't it? Though both the graph are plotting the same points, the former is more fixed, discrete and rigid. Whereas the latter is more smooth and free-flowing. This is the best I could explain the difference between scale and raaga. Scale is the former, Raaga the latter.
If both Raaga and Scale are based on the 7 notes, how does Raaga get the smoothness? It has a unique great weapon - Gamakams!! We will see more about this in the coming posts.
