George Gershwin (1898-1937) bridged the worlds of concert music and American popular song with an instinctive gift for melody and orchestration. His formal training with composers like Rubin Goldmark gave him the tools to craft extended works, but his ear remained rooted in jazz, blues, and the vernacular music of 1920s New York. Rhapsody in Blue, premiered in 1924, became his signature work and one of the most performed American classical compositions, a testament to his ability to write music that satisfies both intellectual rigor and immediate emotional appeal.
