 Whereas stress is typically concerned with one individual word, intonation is generally concerned with the variation in volume and pitch throughout an entire sentence. Intonation carries the message of a sentence. It's particularly important when questioning or agreeing, disagreeing and confirming statements. It's also very important when expressing emotions and feelings. The normal pattern for intonation is the rise, fall. A few examples would be, I haven't seen him for a week, or a simple word as okay. With the falling intonation, we're indicating that we're finished speaking. Again, I haven't seen him for a week, and okay. A few more examples would be, I'll see you at six then. Or a question of information, how do you spell rough? These are straightforward statements that indicate that we're finished speaking and that we don't necessarily need an immediate response. Our second pattern is rather easily recognizable because it's not used as often, and that is the fall rise pattern. This indicates surprise and often disagreement, but above all, it indicates that the speaker wants a person to respond or confirm. We could sarcastically say, you don't really mean that, do you? There I've said, you don't really mean that, do you? I'm obviously indicating that I need a response there. You could also say, are you ready yet? Again, it needs a response, it's perhaps a little agitated, but it's our other fall rise pattern. Are you ready yet? You could also have a sarcastic question such as, are you serious? We are definitely indicating a surprise and we also need a response, but it's a rather sarcastic question rather than a straightforward question where we use the rise fall pattern. Finally, we do have our flat intonation, and our flat intonation basically sends a message that we really are uninterested or not very concerned. These are the flat intonations of a simple just hello. We could say it with our rise fall pattern, hello, or we could say it, hello. Either way, they're all different, but the flat pattern indicates I'm really not too interested. The fall rise pattern of hello sort of indicates that I need a response back, and then again the standard hello is just our standard rise fall pattern.
