Unions between immortal Elves and mortal Men were rare in Middle-earth: the fates of these two kindreds are very different to be interwoven easily. When Elves and Men did intermarry, it was usually for a high, noble purpose, but had a sorrowful end.
Elvish poetry occupies a special place in Tolkien’s Legendarium. It is always instantly recognisable and different from the verse of other peoples in Middle-earth. Varied in style and tone, focus and subject matter, Elvish songs and poems always give a lot of food for thought. Their poems in The Lord of the Rings present a story of their own.
