All the speakers are not excellent, and all the topics don’t have the same interest but I am a big fan of TED, and TEDx conferences… Music often has its place in these conferences.
In the following video, Line 6 co-founder Marcus Ryle tells us the history of guitar from acoustic to the Variax. He tells the basic physics principles behind the sound of a guitar. Maybe you won’t learn much more than you already know but the presentation is quite clear with simple illustrations, and explanations. In other words : it is a very interesting conference… Watch it!
