Once upon a time, I liked Bolero. Then the only classical station at the place I worked played it almost daily. It’s a repetitive piece (even said the composer) so I got to where I’d turn it way down when they played it.Bolero and the 1812 Overture are well known pieces of music.
It was after college that I listened to more classical music. A grocery store was running a special on a collection of classical CD's at some point and I bought all of them. I would listen to one over and over and then get the next one. It was great music to play in the classroom. There was a Suzuki violin program in one of the schools that I taught in, and more than half of my students played the violin.
The thing about classical music is that we all hear it often, as I said earlier, either in movies, television shows, and even commercials. We may not know the name, or hear the whole piece, but we recognize parts of many pieces. The house I sat in last week keeps a radio on 24/7 with classical music playing quietly. You cannot hear it from the bedrooms and it does not compete with the television or other stuff, but if you are quiet, you can identify some of the music. This is done to keep the dog and cat company when they are home alone.
Another common but pretty piece is Canon in D on violin.
