Re: "Well, when I looked up the dates for the different time periods, I found 1730-1820 for Classical. It`s possible that the source wasn`t too reliable, seeing as all I did was do a search on Google a while back."

1730-1820 isn`t unreasonable in and of itself. It just strikes me as a bit arbitrary unqualified. As a rule, however, the Internet is the worst way to research anything. What`s on the Internet is there because someone happened to put it there, and just as often as not that someone doesn`t what he`s talking about. Misinformation abounds.
