The intro is a white screen, the website on the top left,the words "Howcast original" appear and afterwards another set of words describing the lesson appear and it reads "Vibrato Beginner Violin Lessons".  A woman named Julie Artzt Becker is holding her violin is sitting and talking in front of a blue screen.  The woman puts the violin up to her chin and continues to talk.  The woman then puts her fingers onto the strings and with her other hand she touches and points on her fingers on the strings as well as taking the bow to her strings every now and then.  The woman talks throughout the entire video as she's demonstrating her movements or pointing towards her finger motions.  Eventually the woman stops talking and ends with a smile and the words "Howcast original" appear on the white screen.
