Intonation is the movement we introduce into our voices in order to convey meaning. We move our voices up or down or some combination of the two over a tone unit, with our intonation forming an intonation pattern or intonation contour over that unit. We use intonation to indicate attitude, grammatical functions or the organisation of discourse.
Try saying these three sentences in the way indicated in brackets and following the intonation contour given in the lines. Notice how the intonation is different in each sentence and how your voice moves across each contour.
