A poem expressing a single strong emotion, usually the personal feelings of the speaker. Nearly all are short. Often about love, patriotism, fear, etc.

These woods fill me with such delight,
wether wading thought the winding creek
Or gazing at a star-filled night.
I uncover treasuers of rubies and gold,
Defend fortresses high and might,
Slay towering dragons -a sight to behold!
A new adventure waits at every turn.
