A formal poem that reflects on death or other solemn, serious themes?

Elegies are formal poems that reflect on death or other solemn, serious themes.

Explanation:

Usually written to praise and express sorrow for someone who is dead. Although a speech at a funeral is a eulogy, you might later compose an elegy to someone you have loved and lost to the grave.

for me, balancing all your work/homework is the hardest part in high school and the exams.
