Phoenix's Musical Instrument Museum opens this weekend. Claiming to be the first global museum of its kind, it will initially display 3,000 instruments and objects, with every country in the world represented. Instruments will be exhibited in five Geo-Galleries, each focusing on a different region. The museum's European stringed instrument collection features a tenor viol by Leandro Bisiach, an Italian copy of Vuillaume's octobass, an Austrian violin and Swedish nyckelharpas. Other displays include an Apache fiddle, imzad fiddles from north Africa, and the instruments of a complete symphony orchestra dating from around 1850.
