During his stay in London Haydn sketched an _Orfeo_ which he never completed, as the theatre which ordered it failed before it was finished. Only fragments of the work remain, and, fortunately enough, these have been engraved in an orchestra score. These fragments are uneven in value. The dialogue, or recitative, which should bind them together was lost and so we are unable to judge them fairly. Among the fragments is a brilliant aria on Eurydice which is rather ridiculous, while another on Eurydice dying is charming. We also find Mp3 Music for mysterious _English horns_; it is written as for clarinets in B flat and reaches heights which are impossible for the instrument we now know as the English horn. There is also a beautiful bass part. This has been provided with Latin words and is sung in churches. This aria was assigned to a Creon who does not appear in the other fragments. One scene shows Eurydice running up and down the banks pursued by demons. Another depicts the death of Orpheus, killed by the Bacchantes. This score is a curiosity and nothing more, and a reading causes no regret that the work was not completed.
