Research the Veena instruments
Notice: This is a very specialised task, it is open to students who have excelled in previous research tasks!
Right now we still don't have all the different Veena instruments. MusicBrainz aims to be a database not just about current music and instruments, but about historical instruments as well, so even if some of these veena are rare and old, they should still be in the database!
To complete this task: look into the veenas in the sub-tickets under https://tickets.metabrainz.org/browse/INST-392 and document them. Are there any missing ones? Add these and document them as well.
Submit the task once you're done adding your research to the tickets - there's no need to comment anything specifically here, although you are more than welcome to if you want to!
