Intonation is the rising and falling of the pitch of the voice.
When we make a statement, our voice drops at the end of the sentence.
My name is Bob.
I’m going out for dinner tonight.
We love to travel.
We also use falling intonation when asking a question that cannot be answered with yes/no (the “w” questions). Those are the questions that ask; who, what, where, why, when or how. Notice that these words cannot be answered with a simple yes or no answer.
Who is that woman standing next to your wife?

We use rising intonation when asking questions that can be answered by yes or no.
Are you happy today?
Are you going to the movies this weekend?
Is your father feeling better now?
