Review: This Is the First Must-See of the Met Opera’s Season

“Die Frau Ohne Schatten,” a dense ode to fertility, may not sound appealing at first. But in this performance, the fairy tale comes movingly to life.

It’s not easy to make “Die Frau Ohne Schatten” sound appealing.

Believe me, I’ve tried. But when you describe Richard Strauss and Hugo von Hofmannsthal’s most opulent creation, which opened on Friday in one of its infrequent, glittering revivals at the Metropolitan Opera, the piece always seems dense and ponderous.

Starting with the title: “The Woman Without a Shadow.” In this fairy tale, being without a shadow is both a literal condition and a representation of the inability to bear children. The idiosyncratic symbolism only deepens as the plot probes layers of fantastical realms, complete with a singing falcon, a choir of the unborn and the clock ticking down to an emperor’s transformation into stone. Two couples — one human, one demigod — face temptation but persevere through trials to achieve enlightenment and happiness. Oh, and fertility, too.

You might think a four-hour allegorical ode to pregnancy isn’t your thing. But I’m here to tell you: Just go.

With its formidable length and daunting vocal, instrumental and scenic demands, “Frau,” written around the time of World War I, has much in common with Wagner’s “Ring” cycle, to which it nods. And both tend to seem stilted and overblown when summarized.

But like the “Ring,” “Frau” comes alive in performance — its royalty and commoners, flashes of magic and heavy-handed symbols, ending up movingly real and relatable. Hofmannsthal’s elegantly stylized, exquisitely poetic (and, for some, pretentiously contrived) text is warmed by the intensity and compassion of Strauss’s music.
