A song of sorrow or mourning, the Elegy is often for or about someone who has died. However, poets being poets and just that bit contrary on such matters, have also written elegies for the end of something such as a love affair, a holiday, or even a year. Form, meter, and structure are not important, content is what matters.

Example

Silence of Twilight by JezzieG

In that cold silence of twilight
when the ashes of love faded
but never burned out
the moon rose in mourning
to ease my crying heart
as my eyes wept into the night
into the aloneness my life would be
yet as the sun rose in his golden wonder
I felt a warm embrace
reminding me I am not alone
for you will always be with me
