Tone

Definition: Tone is pitch of your voice that goes up and down during you read the poem  

Example:  "Happy Birthday" means much more
Than have a happy day.
Within these words lie lots of things
I never get to say.

It means I love you first of all,
Then thanks for all you do.
It means you mean a lot to me,
And that I'm proud of you.

But most of all, I guess it means
That I am thinking of
Your happiness on this, your day,
With pleasure and with love.

Significance: As the example of poem above, when you read by using tone, you can express your feeling through poem. Tone can make other interest to read poem more.
