PolyCaRe analysis methodology

The analysis is based on the following candidates:

  • 1,600 of the best songs of Raja that I have used as my database (it keeps growing with time) for most analysis purposes. This represents about 35% of his overall number of compositions. These songs are drawn from all the 5 decades from 197x to 201x. It is also from all languages that he has worked on – Tamil, Telugu, Kannada, Malayalam, Hindi
  • About 600 interludes collected from Raja compositions over time (this is a subset of the 1,600 songs)
  • About 400 background scores from various sources including Navin

Having got this database of potential candidates, shortlisting  PolyCaRe candidates is a laborious manual process:

  1. Scan the 1,600 songs’ interludes for PolyCaRe arrangements
  2. A subset of this analysis are the 600 interludes which focus only on the instrument based interludes
  3.  Scan the 400 background scores for PolyCaRe arrangements
  4. Once a candidate has been identified, document the track, its year of release, language, decade of the release (Excel)
  5. For the track, identify  the background instrumentCall and Response foreground instruments and document them
  6. For background scores, exactly identify the start and end positions of a PolyCaRe arrangement in a long recording 
  7.  Pivot the data to identify the PolyCaRe arrangement by background instrument, decade of film release and alphabetic sort of the song within this selection
  8. The data is now available for presentation after these 7 steps. All the exact PolyCaRe arrangements have to be manually extracted from the tracks

Here is the definition of decades as it applies to Raja’s work:

Year range

With this approach, there may be a few songs/BGM scores that qualify more than once as the background instrument is different in two qualifying PolyCaRe arrangements within the same song/BGM scores.

Also, I will present 201x first followed by 200x and so on. This is done deliberately to address detractors who opine that Raja does not do orchestration as well as he used to do in his earlier part of his career. There are several examples from all the decades for many background instruments

hi sir,

just curious, would you share your 1600 songs list, for us to just have the jist of many songs in many languages, surely will be a good reference for rajasir compositions, will you?

To publish the long list of 1,600 plus songs here is meaningless as that is a shortlist based on my taste of Raja's work. However, if you want the list, send me an email and I will send you a spreadsheet with the list.

I would ask you to do me a favor in return. Categorize each song by language and decade and send the list back to me.

If you are good with this, send me an email.
