I play the violin sometimes. Do you know how to play?
I don't.  I know a couple people who play, and I played bass for about a year when I was younger, but I'm not much of a musician.
Ah, well most people aren't. And, everyone has different tastes in both music and the instruments that are used. Violins are the smallest and high-pitched in their family
I usually assume violins are used for classical music.  Do they show up in other types of music much?
Violins are important in many varieties of genres. Sometimes people just don't notice them over other instruments
