In a Handel Opera, a Rare Type of Voice Gets a New Audience

It’s a good time to be a countertenor. Over the last 25 years or so, 18th-century operas, most notably those by Handel, have enjoyed a rebirth in houses around the world, which has allowed the high-register countertenor male voice to sing male roles once reserved mostly for female mezzo-sopranos.

This practice will be on full display this summer in a revival of “Giulio Cesare,” which will run for 15 performances from June 23 to Aug. 23 at Glyndebourne, the summer opera festival in the rolling hills of southern England. Three countertenors have been cast, including as Julius Caesar, a vocally demanding role often given to a mezzo-soprano.

In their heyday, Handel’s operas almost always involved castrati, singers who were castrated as boys to preserve their higher voices but still gained the full lung capacity and overall stamina of grown men. (The practice largely died out in the early 19th century.) Today, however, male countertenors are being cast in roles that were once mostly written for the male voice.

Among singers, casting directors and music experts, countertenors seem to be having a moment.

At Glyndebourne, in this “Giulio Cesare” — a smorgasbord of arias, love stories, historical figures and palace intrigue that goes on for three and a half hours — the three countertenors distinguish themselves not only in character but also in voice. For Aryeh Nussbaum Cohen, who is singing the title role for the first time in a full production (he sang it in concert in Moscow in 2021) it’s a phenomenon that many opera fans might not think about for what is considered the rarest voice type.
