Established by Royal Decree, Royal Opera House Muscat is a beautiful venue dedicated to the diverse artistic and cultural expressions from the Sultanate, the region, and the world. The design for the Opera Hall was a collaboration between the in-house interior designers of the Royal Court of Oman and a UK-based design team-including ACOUSTIC DIMENSIONS and architects WATG. Although the building is called an opera house, it actually transforms into a classical concert hall and into a world-class organ recital hall. It reflects the model of the early European concert halls and opera houses. A reverberation chamber is included to support the acoustics for the pipe organ and adjustable acoustic elements are concealed behind elaborately carved screens to transform the acoustics for amplified sound. Opening performances include Placido Domingo and the Mariinsky Ballet with future seasons highlighting Omani art, as well as collaborations between leading Arab, Indian, Asian, African and Western artists.
