These are the videos I posted on the Moodle site for students, for self-study in intonation. All are by the same online teacher, who does a really fabulous job, taking learners into the world of stress patterns with practice sentences like this:
Clients get haircuts.
Clients will get haircuts.
His clients will get haircuts.
His clients will get good haircuts.
All of his clients will get good haircuts.
