Film-song evidence method

How was the raag identified?

Ragapedia does not use AI audio recognition. Software tidies song details and removes duplicates; only a checked source can put a raag on a song page, and only a musician's review marks it as reviewed.

1. A checked source names the raag

A raag is shown only when a source we have read names it for that song: the composer's own words, a named musician's or researcher's analysis, a participant's recollection, or label documentation. Ragapedia does not listen to a recording and declare a raag on its own.

2. The evidence is recorded exactly

Each claim keeps its source, the exact page, paragraph or timestamp, and the source's own wording. Unattributed discovery indexes stay private. A named researcher's explicit song–raag table can support a reported attribution, but does not establish an individual musical analysis or a checked recording.

3. Musicians review it

Every claim says whether a musician has reviewed it yet. A review checks the claim against the exact recording. Rejected and disputed claims are not shown.

4. Counts show their scope

Raag and artist totals include published songs whose raag comes from a cited source. These songs are labelled not yet reviewed by a musician until review. A song counts towards the catalogue target when a named source states its raag with an exact page or passage, and the song is a Hindi film song from 1960 or later in the open-data song list. Musical review is not required to count.

What the system does not claim

  • No automatic raag detector has classified these film recordings.
  • A matching note set is not treated as sufficient; melodic movement and characteristic phrases matter.
  • A recording link is not a timestamp. Phrase timestamps appear only after a reviewer enters and verifies them.
  • Catalog counts describe the declared source corpus, not every Hindi film song ever released.
  • A composer's statement records what the composer said; it is not a note-by-note check of the recording.
  • Several pages that repeat the same statement count as one source, not several.

Source treatment

For the musical principle behind review, the method follows the distinction between a pitch structure and chalan: film composers may depart from a raag, and two raags can share notes while moving differently.
