The Sound of the Empire – Klingon opera was a well-known genre of traditional Klingon music with certain dramatic and stylistic similarities to Human opera. Typical themes including the passionate tales of doomed courage and star-crossed love. Its strident tones were considered ear-shattering by most non-Klingons. One of the famous Klingon opera singer was Barak-Kadan, while a noted opera writer was Keedera. Worf was an aficionado of Klingon opera and owned a sizable collection, which he often played at high volume over USS Defiant speakers.
Klingon opera was a required subject of study in Federation secondary schools. In 2370, Jake Sisko had an exam on Klingon opera. Although he was confident, Benjamin Sisko believed he would not gain an “appreciation” of it by not studying it thoroughly.
Whilist on Earth, ’U’ is the first opera in the Klingon language, billed as “The first authentic Klingon opera on Earth”. It was composed by Eef van Breen to a libretto by Kees Ligtelijn and Marc Okrand under the artistic direction of Floris Schönfeld. The story of ’U’ is based on the epic legend of “Kahless the Unforgettable”, a messianic figure in the fictional Klingon history.
Needless to say, the Klingons are passionate opera lovers. “Klingon opera uses the principle of musical combat. Beauty in Klingon music comes from the impact of two opposing forces.” ’U’ is translated to English as “universe” or “universal”.
On 18 April 2010, Okrand, on behalf of the KTRE, broadcast a message from the CAMRAS radio telescope to the hypothetical co-ordinates of Qo’noS, the Klingon home planet, in the Arcturus solar system.
