This pretty arrangement has, unfortunately, not been followed in the modern editions of these symphonies.

In the works written in London the clarinet has utterly forgotten its origins.

It has left the somewhat plebeian world of the brasses and has gained admittance to the more refined society of the woods.

Haydn, in his first attempts, took advantage of the beautiful heavy tones, "_chalumeau_," and the flexibility and marvellous range of a beautiful instrument.
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.
