Please read the accompanying article that provides more details into the how and what of spinal waves:
Trailer Music: http://johnclarkemusic.com/
In this video I demonstrate and explain a drill that I use on myself and with my students to develop awareness of the entire spine, its capacity to undulate and wave, and individual awareness of each vertebra and its position both in space and relative to the other vertebra. I have purposefully left some details vague so as to encourage the viewer to explore for themselves, so instead of thinking of these as "the correct way to do things", try to think of them instead as clues that will help you perform your own in depth explorations.
Many people have had a profound influence and impact on my training, and I am forever grateful to these people. They are too numerous to list here, although you can find a links to most of their websites on my resources page: http://awarerelaxedconnected.com.au/resources
Please take some time to check these people out, and support them where possible - their work is something of a treasure in the modern age.
