All of the responses so far are correct (except maybe for Gershwin - although he did write a piano concerto, it was in popular/jazz influenced style - not what is usually included in a definition of *classical* music.) HOWEVR - there are going to be people here who will nit-pick - because the term "classical music" is often used to mean "music written for artistic purposes" as opposed to a film score, popular dance music, etc.) They will say that classical music ( often with a capital C) means music written ONLY in the period of the 18th century that had composers such as Mozart, Haydn, Beethoven, etc. So sometimes in contect, you can tell is the person asking means classical PERIOD as contrasted with Baroque, Impressionistic, etc. - of classical music - all of it, from Day One to now. You second question falls into the "classical period" definition.
