Here goes. A disclaimer: none of the statements/concepts/principles explained here are categorical or rigorous in the scientific sense. There is always flexibility and deviation. Viewing of musicological theories and statements in a categorical manner leads to a distorted view.vasanthakokilam wrote:SR, can you explain some more on this topic for the HM uninitiated?
The ultimate aesthetic criteria are the same whether in HM or CM: "ranjayati iti rAgah". What is important for the discussion on Raga Moods is how you get to that stage.
HM is primarily a mood-based raga system; the seed material for ragas is rarely a scale but rather certain characteristic clusters that convey fairly specific moods or rasas. Note the word "rAga" translates closely as "mood/emotion" and not "scale". The vadi-samvadi concept somewhat naturally arises from this approach. The vadi swara is an anchor around which the "mood" is developed . As I said, this concept is not a rigorous one, and essentially will become more and more blurred as HM and CM increasingly "mesh" with each other (see below). But the very fact that HM is centered around the notion of certain tonal clusters or phrases that create certain pleasing effects, makes it quite useful for understanding "Raga Moods".
CM is primarily a scale-based raga system. Part of this approach seems to derive from the music of the old Tamils (I am by no means an expert on the "paN" system but I believe it was strongly scale-based). Roughly speaking, a scale is chosen and then a complex raga is developed around this scale to the extent that the choice of scale allows. As a result, several different moods can exist within the same raga since one does not start with a specific cluster of swaras that one likes and which creates a certain "mood" or "emotional suggestion". In relatively recent times, we have many examples of such ragas, especially after the meLa system was formalized. Ragas like Sankarabharanam, Kalyani, and Subhapantuvarali represent the high point of the CM "scale-based" approach.
Let me be very clear that there are also a number of current CM ragas that likely do not originate only from a scale. But if we look into the history of many of these ragas, we often discover that they originate from the time when CM and HM were not separated. The detailed discussion of athana in a previous thread, and also in this one, is a case in point.
Returning to the topic: For a very specific example, I will use bhupali-deshkar-mohanam, all of the same "scale" S R G P D. The first two HM ragas are considered two separate ragas exactly because of the "mood-based" approach. Bhupali is a purvanga-pradhana raga. It centers around the G swara (vadi) and is supported by D (samvadi) which provides the "closure" in the uttaranga. It conveys shanta and shringara rasas very well. On the other hand, deshkar is an uttaranga-pradhana raga. The main activities are around the D and the G is now the samvadi swara to provide the closure at the purvanga end. Deshkar has a strident, even euphoric tone which conveys vira and raudra rasas well.
The CM raga mohanam originates directly from the above pentatonic scale (of Sangam-era vintage, I believe. I may be mistaken). Since the vadi-samvadi approach is absent, it integrates features of both bhupali and deshkar within the same CM raga. In the past, this difference has created a certain amount of misunderstanding and nonsensical rhetoric on both sides: HM theorists would comment on the fact that CM misses these finer points that are fundamental to their concept of raga (i.e., emotion), while CM theorists would consider these differences to be too minor and would stress the advantages of the enlarged melodic scope afforded within a scale-based system.
Ideally, a good composer should reflect upon these issues before composing. As I mentioned (and others have also pointed out using Tyagaraja as an easy-to-understand model), the crux of CM is an intricate combination of raga and sahitya that strongly reinforce each other, ultimately to convey a certain meaning (which includes shades of emotion). My composition "manamOhanEna rakshitOham" (see Contemporary Compositions thread, page 3) is a product of such specific contemplation. Here is the recording again:

The pallavi-anupallavi portion is essentially the "bhoopali" face of mohanam if you will, and mostly conveys "gentler" characteristics of the subject. But the whole mood decisively changes in the charanam, which is the "deshkar" face of mohanam. The whole activity is centered around the uttaranga and creates a strident, militaristic, victorious mood. This musical theme is hammered upon repeatedly in the charanam to drive home the message of power and dominance that is clearly expressed by the words in the sahitya.
