If you're looking for "Classical" music as in music from the Classical period, then you're looking for Mozart, Haydn, or Beethoven. For Mozart, my personal favorites are his Clarinet Concerto (get the Robert Marcellus recording), Symphonies no. 40 and 41, and The Serenade no. 10 or "Gran Partita". I haven't listened to much Haydn, but he wrote over 100 symphonies, so there's bound to be at least one you like! As for Beethoven, he essentially defined every genre he wrote in, from symphony to string quartet to piano sonata, so anything with his name on it is awesome.
If you're looking for "Classical" music as in music that isn't pop, then I'd still recommend Mozart, Haydn, and Beethoven, but also add in some of my favorites like Dmitri Shostakovich, Samuel Barber, and Johannes Brahms. Can't go wrong with any of those guys.
I would add some examples, but due to my low post count I don't actually know how to do that, so I'll just trust you to find that stuff on your own
