g string - The third string on a five-string banjo. It’s like the brain

The third string on a five-string banjo. It’s like the brain of the banjo. If it breaks, you sound like a sad monkey.

I broke my g string on my banjo, and now I sound like a sad monkey.

My friend’s banjo has a broken g string, and it sounds like a sad monkey too.

My teacher said my g string was the most broken one in the class.
