In this video, Kevin Richards teaches us some vocal exercises and how to expand the upper range of the head register voice for singing. The exercise, a "reverse octave", involves starting at a high note (in the head register) with a "He" sound, and singing down an octave to end up with a "Ya" sound. The purpose of this is that making the "h" sound in "He" works the diaphragm. Richards will explain this and demonstrate it in the video. After learning how to do the exercise, you will learn helpful tips and advice on what to watch out for and make sure of when trying it yourself, as well as an example of what would show you're practicing the exercise wrong.
