The 1691 premiered semi-Opera King Arthur of the "Orpheus britannicus" Henry Purcell, John Dryden wrote the libretto to which, combines drama, music, dance and spectacle. "Music and poetry can be for themselves, but they will produce the most striking effect if they are United, spirit and beauty in a person," wrote the Dryden has been active since 1668 as poet laureate at the Royal Court. In five acts, King Arthur his fiancée, the blind Princess Emmeline, strives to get out of the arms of the Saxon King Oswald of Kent. The triumph of the Italian Opera supplanted the once successful piece, it fell into oblivion. Purcell's handwritten score is now considered lost, and the more than 60 different surviving sources contradict each other. The composer Helmut Jasbar has complemented the work by contemporary items from the fields of classical music, as well as the visualization. The famous Aria of the cold genius shows Jasbar in numerous variations, but remains the core of the composition by Purcell. With the addition of new timbres, newly composed interludes and playbacks is a mixing sound, which expanded Purcell's King Arthur by choir and Orchestra and electronics.
