Book excerpt: Burleigh (both African Americans), Horatio Parker, and Maurice Arnold - to forge a uniquely American tradition; they, in turn, became mentors and teachers to a new generation of composers, including Charles Ives, George Gershwin, Aaron Copland, and Duke Ellington. Dvorak heard for himself the "dialects and idioms ... commingled in this great country" and expressed them in his own way in a dozen masterpieces written during his visit. His "New World" Symphony, for example - still the most famous ever written on American soil - was composed in New York amid what he called the "American push" of the streets. And two of his most celebrated chamber works, the F Major Quartet and the E-flat Major Quintet, were written during his travels through the prairies of northeast Iowa, which he described as the "American Sahara." The contributors to this anthology are among the world's most distinguished authorities on Dvorak.
