You;re welcome! I only happen to know this stuff since I once had to score some arrangements for solo (Ukrainian) dom(b)ra & string orchestra, and I wanted to know as much as possible about the dombra's specifics.
In fact Wikipedia is often inconsistent between acticles (naturally so, since there is no single author or editor)
Theiir page giving the tunings of all stringed instruments (
https://en.wikipedia.org/wiki/Stringed_instrument_tunings) lists both the
domBra and also the
domra (
https://en.wikipedia.org/wiki/Domra) on whose (separate) page the 4-string tuning (and its similarity to violins and mandolins) is mentioned.
It's a pity the domBra page makes no mention of the other instrument, even by way of clarification. Here in Russia, the
domra is a popular instrument in schools - as it makes a starting point for the violin, for those who have the patrience and enthusiais :-))
When I was at the Pokrovsky Chamber Opera last year for their production of DSCH's THE NOSE, I noticed that the fiddle players nobly put down their violins as marked in the score - but instead of picking up triangular balaklaikas (as Shostakovich marked), they all used domras instead. Only the purest of purists might quibble?
