After conquering England by triumphal performances of Der Freischütz at Covent Garden von Weber was sent a commission by the manager of The Royal Opera House Covent Garden that resulted in his new opera Oberon.The overture prepares us for the opera by working some of its main elements.Oberon's magic horn opens the way, and we hear the chivalry of Charlemagne's court, the fairy footsteps of the first aria and the clarinet intoning Oberon's aria.
