Find me a picture of any orchestra pit in the world where someone is playing left handed. I would love to see the person next to them taking a bow to the neck. You would need a whole section of them and have to isolate them from everyone else.I mean, this is just factually wrong. Most string instruments have been played in right and left handed orientations since they've existed. It's just that it's only with cutaways and electronics etc that instruments have been inherently ambidextrous.
Like, lefty cellos and violins are a thing. They just only require a different bridge and but at most.
