I was most excited about the musical performance part of the event, but it turns out the lecture part might have more lasting impact.
His lecture was about the history of raga forms, and his own views on the degradation of raga forms from an organic aesthetically-guided musicality to a synthetic computational model. The great loss, according to T. M. Krisha, is the ability to spontaneously feel the belonging of any part of the raga to whole. The synthetic ragas must mechanically repeat phrasings to maintain its re-cognitive character.
What shocked and excited me about what he was saying is that this precisely is a distinction I have been trying to make in my own philosophical work, distinguishing between synthetic ideas — which must be explicitly recalled and applied in constructing thoughts — versus conceptive ideas which work spontaneously and produce givens: givens of perception, of interpretation and of thought. The acquisition of a new conceptive capacity gives us new givens from nowhere, expanding our ontological range, thus enlarging our enworldment and enabling us to accommodate more truth.
I feel certain that my profound philosophical — or better, praxic — kinship with T. M. Krishna’s accounts for my instant love of his music. I conceive his music as an auditory embodiment of the very ideas that animate my thinking.
India is a living superset of every possible philosophical idea humanity will ever conceive, so I am overjoyed, but not at all surprised, to have reconceived an Indian enworldment..
I dug through T. M. Krishna’s book, A Southern Music and found some of the content from his lecture:
In the early eighteenth century, Venkatamakhin’s descendent Muddu Venkatamakhin decided to artificially create ragas for the remaining fifty-three of the seventy-two possible melas computed by his ancestor Venkatamakhin. He used the same method that had been used to create the raga deshisimharavam. This meant that all seventy-two melas were functional. The raganga raga needed to have only the seven svaras. It was around this time that arohana and avarohana came to be used to define the melodic structure of a raga. This created artificial janya ragas that were formulated from the non-functional melas. As these ragas had no aesthetic component to their identity, the simplest way to describe them was to mention the svaras that appeared in their arohana and avarohana. These svaras were after all based on the computed svarasthanas. This was another important marker in raga history. Even under the constructed melas, Muddu Venkatamakhin placed older, naturally evolved ragas. He not only gave names to all the fifty-three raganga ragas that he constructed, but also altered the names of older raganga ragas. This was done to accommodate the ingenious syllabo-numeric memory system that was evolved to identify the number of the mela from the name of the raganga raga, a system called the katapayadi samkhya.
As I move to the next major development, I must point out that the exercise of computation resulted in ragas being reinterpreted in terms of only the svaras they contained, rather than the aesthetic form of their melodic movements. This is also revealed in the use of arohana and avarohana as the defining characteristic of ragas. We must realize that once these systems came into practice, they were also being placed upon ragas that had evolved organically and were not determined by the arohana or avarohana. All ragas were being looked at through the prism of the arohana and avarohana, thus deconstructing their natural melodic features. …
Ragas that evolved from melodic phraseology developed through time and remained cohesively held together by the aesthetic cognition of unity. These ragas may have seven svaras or even less. They cannot be purely defined by the sequence of the svaras in the arohana or avarohana. Examples of this are surati, ritigaula, anandabhairavi, gaula and saveri. …
In the eighteenth century, we come across another treatise called Sangraha Chudamani (1750–1800). We know very little about the treatise or its author Govinda (not to be confused with Govinda Dikshita). This treatise completely sterilized the concept of raga and mela. Govinda combined the ideas of sampurna along with arohana and avarohana. In doing so, he decided that the ragas that held the name of the mela must have all the seven svaras in sequential order both in the arohana and avarohana. He also created a new term for the melakarta: meladhikara (the raga that has authority over the mela). Most ragas that evolved naturally did not have svaras in linear sequence and could not be meladhikaras. Only six older ragas were given the meladhikara status. Older natural ragas were listed within artificial melas whose meladhikara was a synthetic raga. The status of the raga that held the title for the mela had thus changed from being the most popular raga to the one that had authority over the mela…
With these conceptual changes to raga and the adaptation of many forms of contrived svara sequences as ragas, we are faced with an aesthetic challenge. Do all these different types of ragas have the abstract nature that is a creation of the raga’s musical heritage, phraseology and its psychological recognition? An aware listener can sense this by listening to just one phrase. In an artificial raga, the musician and the listener have to constantly connect with all the svaras present and their sequence. They cannot transcend this level of engagement and move to the real level of aesthetics of phrase forms. Why is such transcendence important?
Let me suggest an answer to that question. A raga belongs not to the literal but to the inferred. The inferred comes alive when the perceiver can be invited into the sound of the raga, which is born from every svara, every phrase, every phrase connection and the raga as a whole. This experience is only possible when the listener does not need to be reminded of the technical nature of the svara or its sequence. Synthetic ragas lack the abstractive nature both in form and in the way they can be received.
