- D major.
Finally, the fifth movement is amazing; a long and continued tone of the F horn gives the signal to return to reality and cheerfulness. The gloomy atmosphere of the first two movements is blown away, the tender romance of the fourth movement is left behind. Serene calmness reigns, an exuberant Allegro romps around from one key to the other as if the depressions of before had never existed.
True joy of life rules again, rising to new heights still higher until the grandiose, brightly shining climax in the key of D major. We are back to life again!
