Intonation is "the music of the language". Not only does the language sound natural, but also may change the meaning of some sentences, and it certainly does change the effect our sentences have on a native listener. British and American intonation are different: intonation top pitch is much higher in BrE, and low pitch can be a bit lower in BrE, so British people sound much more like singing when they speak, and not so much American people. But apart from that, intonation is basically the same, so we are going to use a series of 4 American videos to show you how intonation works in English.
