People who attend our workshops or events never fail to report being astounded by the content, yet visitors to the website seem somewhat bemused or lost.  This is because of a number of reasons (not least due to the organisation and content of the site).  To try to offer some greater insight in a more digestible form, we've decided to invest more in our lovely visitors and give some video content to help you understand some of the material.  Here, Darren (aka Magpie) examines the significance of sound.  Enjoy!
