OPUS | Violinist-turned-playwright Michael Hollinger’s drama, which is enjoying a sharp New England premiere by New Repertory Theatre (at the Arsenal Center for the Arts through April 17), explores the intense, near-familial intimacy of artistic collaboration by peeping through the off-stage keyhole as a renowned string quartet, some 10 years into its four-way musical marriage, comes unstrung. Although some clinkers — and a glaringly wrong note at the end — are struck, the 90-minute play boasts a cleverly musical construction (reflected in Cristina Todesco’s set design, in essence a platform hung from strings) as well as a light touch. And under Boston University School of Theatre head Jim Petosa’s direction, the work is performed as subtly as its melodramatic ornaments will allow by a quintet of performers — Benjamin Evett, Michael Kaye, Shelley Bolman, Bates Wilder, and Becky Webber — who string-synch serviceably to snatches of recorded Bartók and Beethoven and whose individual members demonstrate that, if even they can’t really play their instruments, they can keep Opus in fine tune. | New Repertory Theatre, 321 Arsenal St, Watertown | 617.923.8487 | Through April 17 | Curtain 7:30 pm Thurs | 8 pm Fri | 3:30 + 8 pm Sat | $35-$54; $27-$49 seniors; half-price student reservations
