Hello. I don't quite understand what the underlined sentence means in the context below.
Does "musical" mean "go back and forth between silince and thunderstorm" or something?
Please help. Thank you.

from A Bird on Water Street by Elizabeth O. Dulemba----
Things were so tense between my parents that it was the last place I wanted to be.
Their silence hovered in the air like the static electricity, and when they did talk, it was a thunderstorm.
Mom was sure the mine was closed for good and that Dad should start looking for a job somewhere else.
But Dad was convinced the Company would come around.
I was just tired of tiptoeing around them and eating beans for dinner. I swore if I ate one more bean, I would explode.
My whole family had gotten quite musical, and I don't mean singing.
Eating a lot of beans results in a great deal of flatulence.
