The name of 17th-century violin maker Antonio Stradivari - or Stradivarius as he is usually known - is one that sends shivers down the spine of music lovers the world over. During his lifetime Stradivari made over 1,000 instruments, about 650 of which still survive. Their sound is legendary and for any violinist the opportunity to play one is a great privilege. 　　Clemency Burton-...
