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 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.
