CAMBRIDGE - Of all the tricky things about staging the works of Anton Chekhov, getting the tone right is the trickiest. Like a sunset, a fire opal, or a shimmering mist, a Chekhov play makes even the strongest impressions through the accretion of a thousand tiny variations in shade. Push any one color - comedy, tragedy, oddity, romance - too hard, and the thing congeals into a caricature of itself.
Earlier generations overstressed the tragic; even the archetypal Chekhov interpreter, Konstantin Stanislavsky, made "The Cherry Orchard" more maudlin than its creator desired. These days we seem to be veering more toward the comic end of the spectrum, perhaps out of a desire to avoid the lugubrious excesses of the past. But surely it's possible to find a range of tones instead of hammering away at just one.
