Tone

Definition: The way something is said, the pitch in which something is said, the attitude of a poem.

Example:

From one thousand mountains the birds' flights are gone;

From ten thousand byways the human track has vanished.

In a single boat, an aged man, straw cloak and hat,

Fishes alone; snow falls, cold in the river

Significance: Tone is important in poetry because it dictates the way people interpret the poem. Changing the poem's tone can completely change it's meaning or feel.
