hi, I was going to add https://tickets.metabrainz.org/browse/INST-64 so therefore I did some research.
turns out it's a convoluted mess and very many instruments are called "tamboura" "tam/nbor" or similar.
I matched instruments on the linked page with the ones I found on https://en.wikipedia.org/wiki/Tamburica
however it became clear that "tamburica" is the general term for this balcanian string orchestra while reading http://www.atlasofpluckedinstruments.com/europe2.htm
The instruments we already have on mb is a big mess, https://beta.musicbrainz.org/instrument/4568d593-e1d5-4516-bbe9-391adc016155 is the biggest reason I made this community post, since I believe we should split this out to the instruments I will be creating, @wonder_al and @sparkinson you've added this to several recordings with instrument credits of the aforementioned, would you be interested in helping me move those instruments over when I've created those? (if not it's just one page so I can probably do them myself) there are a couple however without a credit, I don't know what they are.
https://en.wikipedia.org/wiki/Tambura_%28instrument%29 seems to be talking about the generic instrument played in the balkan, while https://en.wikipedia.org/wiki/Tamburica talks about the instruments in the tamburica orchestra
Our "tambura" doesn't really have much disambiguation https://beta.musicbrainz.org/instrument/b9362496-01a3-4298-b369-84313cec5ee1
and I suspect it's been misused for all sorts of unrelated tambour instruments, in it's day, nikkibot had added aliases to it that are the one listed on https://en.wikipedia.org/wiki/Tamburica not the ones on https://en.wikipedia.org/wiki/Tambura_(instrument) (which given the confusion of these you can't really blame on anyone.)
Our tambura has also been used for the Indian Tanpura: https://beta.musicbrainz.org/instrument/b9362496-01a3-4298-b369-84313cec5ee1/recordings?page=4 which should probably be moved to https://beta.musicbrainz.org/instrument/16f816ec-9ecf-4236-8006-19a4b27797f1 ?
There is also the related instrument tabouras, that's also called taboura, tambouras or saz, it's related to the turkish saz/baglama and an ancestor of the bouzouki. http://www.atlasofpluckedinstruments.com/europe3.htm
Furthermore there is the other "Tanbur": https://en.wikipedia.org/wiki/Tanbur
all of these are related to each other, and I'd love other people's input so we can together untangle these if possible.
Wikipedia's Tambura seems to talk one of the Tambouritza's, how is it related and with our "tamboura" that's a mess of other instruments (see above)
Anyone have any ideas, please discuss, also @reosarevok ping :P
edit: seems esperanto wikipedia has a comprehensive list https://eo.wikipedia.org/wiki/Tamburao
