It is as important to teach learners prosodic features as successful communication depends as much on intonation, stress and rhythm as on the correct pronunciation of sounds.
Example
Intonation, stress and rhythm are prosodic features.
In the classroom
One way to focus learners on various aspects of prosody is to select a text suitable to be read aloud - for example a famous speech - and ask learners to mark where they think pauses, main stress, linking, and intonation changes occur. They can then practise reading this aloud.
