The names of these traditions — gharana, bani, teaching line, regional style — describe different things, and each entry says which it is. Where a teaching link is shown, a sentence in a named source supports it. Where it is not, we say so, and the claim stays unpublished.
This is growing research rather than a complete map. Not every instrument organises itself into gharanas, many musicians here do not yet have a page of their own, and dates, founders and teaching links are left out wherever a source has not yet settled them. Additions are read by an editor before they appear. Carnatic traditions are a later phase.
