Few choreographers today seem to want to make significant points about the Meaning of Life. But there are still plenty of ballet cliches around (uses of music, uses of choreography, ways of presenting dancers or "characters", attempts to manipulate the audience).
Is it because so many boring ballets have been set to his music that I have come to dislike Mahler? The Mahler ballet: someone sings lugubriously from the side of the stage while dancers toil up Angst Hill and down Weltschmerz Dale for hours on end. Sexuallity, if not repressed, is ambiguous; a Death Figure is bound to turn up somewhere. Mahler is the favorite composer of the deep-think choreographers -- the one they all rely on to dye their musings the rich dark brown of significance.
It would be great to hear about the cliches that you yourself have observed and found grating. Who knows, we might help a few would-be choreographers to avoid them in the future.
