Earlier this year, I wrote about a post about epitaphs. At that time, I made the decision to not combine them with elegies.
An elegy is a song of sorrow or mourning--often for someone who has died. However, poets being an especially creative and contrary group have also written elegies for the ends of things, whether a life, a love affair, a great era, a football season, etc.
While there are such things as elegiac couplets and elegiac stanzas, form does not rule an elegy; content is king (or queen) when writing elegies.
Play with poetic forms!
Poetic forms are fun poetic games, and this digital guide collects more than 100 poetic forms, including more established poetic forms (like sestinas and sonnets) and newer invented forms (like golden shovels and fibs).
Here are some examples:
"Elegy in Present Tense," by Nancy Krygowski
"Elegy Written in a Country Courtyard," by Thomas Gray
