Violins don't belong in Elder Scrolls. It's a too modern instrument to fit that world
You can have lyras instead.
Lutes are okay.
Flute yes.
Drum yes.
Harpe yes.
Sack-pipe possibly.
Violins aren't modern at all. And surely if elves figured out how to make a lute, they could figure out how to turn it sideways and invent a violin from that. We only see a paucity of the musical representation in the TES world, since TES is a fighting D&D based game. It's not a game about music or cooking or living a regular life. But I'd very much like it to incorporate all those elements, especially music.
