So the question is - is the so-called "canon" (even if it's more of a mental boundary) too strict? Do some of these composers that have been honored over and over again for as long as we can remember deserve their place in the "world" of classical music more so than great composers from other periods that perhaps most people are less familiar with? Why is it that this canon continues to remain in place and seems so immutable to us - can this general perception be easily altered?
Finally - what other composers do you think could stand up to canonical names in terms of "greatness" even though they have been comparatively neglected due to unfamiliarity with their time period or other factors?
I hope that I have made my point clear.
