It’s a delicate process, and the opera house has been closed for a year. “The team has brought in physicists, engineers, architects and other experts to preserve the delicacy of the horseshoe-shaped auditorium’s sound, preventing even slight modifications to seat structure during storage. Artists will test the sound quality when the theater reopens for its 100th anniversary in May next year, which will be celebrated with a performance of Verdi’s ‘Aida,’ the same opera that opened the venue in 1908.”
