Looking at the article there seems to be a genetic component, but no one in my family has ever mentioned them, I should go ask.
We are not a "musical" family. No one plays competently any instruments or goes to concerts. I have an ukulele that I use mostly as a noisy version of a fidget spinner.
From the article I see that the openmindedness trait fits, at least musically: I sometimes go on YouTube musical late night binges and they can easily range from Renaissance guitar pieces to KPop via Mozart, Slipknot or some obscure Latvian folklore.
