Where in the World is Mr. Arpeggio? Postcards Only Motivate. Practice. Meet Composers. Music students are transforming into music super heroes to find an international villain, Mr. Arpeggio, who is traveling the world stealing music terms and symbols. But where in the world is Mr. Arpeggio? Suddenly, students are practicing more than ever to earn squares on the giant game board hung in the studio, to meet and interview composers and gain super music powers and knowledge! Visiting each destination only once, students must visit all 20 countries to earn all available postcards, one at a time. The back of the postcard provides an interview with the composer, or article giving students information about world composers, music concepts, terms and symbols and subtle clues to Mr. Arpeggio’s whereabouts in a fun and interesting way.
