Intonation is a crucial element or verbal interaction. Authors of teacher’s handbooks and teaching materials agree on this. The communicative importance of intonation should also be reflected in the attention it gets in language teaching.
There are different ways in which human sound is processed. The idea to emphasis is that all this is done in order to communicate.
Intonation is often defined as a speech melody, consisting of different tones, obviously, what melody and intonation have in common is that in both we make our voice go up or down at will. It means, the tones depend on the pitch of the voice.
There are seven or eight tones but the more commons in English are the follow combinations:”down – up”= falling rising tone and “up – down “= rising – falling.
FALL
RISE
RISE – FALL
FALL – RISE

The classic example of intonation is the question-statement distinction. For example, northeastern American English, like very many languages, have a rising intonation for each declarative questions (He found it on the street?), and a falling intonation for wh-questions (Where did he find it?) and statement (He found it on the street.) Yes or no question (Did he find it on the street?) often have a rising end, but not always, For example.
He: Why?
She: Problems.
He: Problems?
She: Yes.
He: What?
She: Babysitter.
