Tone

Definition: The high and low pitch of the sound you made when reading / singing / talking outloud.

Example:
When I see your face
There's not a thing that I would change
'Cause you're amazing
Just the way you are
And when you smile
The whole world stops and stares for a while
'Cause girl you're amazing
Just the way you are

Just the way you are - Bruno Mars

Significance: When reading outloud a poem with tone, you give it more feeling and emotion which make it interesting
