This piece by Liszt is about a story of love and loss due to death and is based on a poem by Ferdinand Freiligrath. The poem prompts the readers to love as long as and as best as they can, reminding them of the inevitable loss of love due to death. The emotion of this poem is what really formed the style and melody of "Liebestraum No 3".
Through the music, Liszt engages our emotions by reminding us of the impermanence of life and the strength of love. A strong message which is at the same time melancholic and invigorating, in the sense that it urges us to see life and love under a new perspective. With the music following its path, the poem starts like this:
O love as long as you can,
O love as long as you may,
The time will come, the time will come,
When you will stand at the grave and mourn
