At first the 'cellos, also, re-enforce this melody.
The effect is that of an ethereal voice commenting on the beauty of the main theme. This obligato part is of special significance, since with rhythmic change it forms the chief theme of the Trio in the following movement. The Romanze closes with a simple return to the plaintive oboe melody, this time in D minor. The tonality is purposely indefinite to accentuate the wistful feeling of the movement—the last chords having the suspense of a dominant ending.
