Compose a classical piece that specifically explores the feeling of loss of a loved one. The piece should begin with a mournful and melancholic tone, but eventually build to a more cathartic and uplifting ending. The instrumental arrangement should include strings, woodwinds, and piano, and should use techniques such as dissonance and variation in dynamics to convey the emotional depth of the theme. The piece should be at least 5 minutes in length and should aim to evoke a range of emotions, including sadness, longing, and hope.
