We've had different discussions in the past about various different musical genres, and how they're classified and such, but I'm a little curious as to when the "cut-off-date" (for lack of a better word) is for music that's considered to be classified as "classical." The reason I ask is because much of the classical music we have is centuries old from composers like Mozart, Bach, Beethoven, Handel, Schubert, and so forth - we're talking like 1600s, 1700s, and even 1800s. Then there's the work of Joplin, which many also consider to be classical music as well, yet it was considerably more recent - the early 1900s, to be exact, which was just over a hundred years ago. Are we so far ahead in terms of our time and music that anything that came before, say, the rock-n-roll era of the 1950s is now considered classical?
