A work written during World War II. At that time, Hyde's husband was deployed to war and later captured as a prisoner of war in Germany. The second theme of the first movement of this work is a "love theme" dedicated to her husband, appearing in various forms throughout all three movements of the piece. The second movement is somber, but the third movement concludes brightly, as if celebrating victory. Although a sonata, it is rich in narrative and adorned with passionate passages.
