A Stradivarius is a stringed instrument built by members of the
Stradivari family, particularly Antonio Stradivari. The bowed
instruments are famous for the quality of their sound, which has
defied attempts to explain or reproduce. The name "Stradivarius"
has also become a superlative applied to designate excellence. To
be called "the Stradivari" of any field is to be deemed the finest
there is.
