“Introduction to Stradivarius” by Peter Sheppard Skaerved http://www.rdiaz.org/rdmagazine52-29jun14.html#magazinerec1

On the following video “Introduction to Stradivarius” you can learn from a learned expert maestro Peter Sheppard Skaerved who is playing 6 Strad violins there and explaining about how much such master luthiers like Nicolò Amati (1596–1684) and Antonio Stradivari (1644–1737) re-invented the violin itself from what it used to be, to what we know today.
