Aaron Copland, born on November 14, 1900, in Brooklyn, New York, was a seminal American composer renowned for his distinctive musical portrayal of American themes. The youngest of five children in a Jewish family of Lithuanian descent, Copland developed an early interest in music, initially learning piano from his older sister. He pursued formal studies under Rubin Goldmark in Manhattan before traveling to France to study with the influential teacher Nadia Boulanger at the Fontainebleau School.

Copland's early works were influenced by jazz rhythms and the neoclassical style of Igor Stravinsky. However, during the Great Depression, he shifted towards a more accessible style, creating what he termed "vernacular" music. This approach led to some of his most famous compositions, including the ballets "Appalachian Spring," "Billy the Kid," and "Rodeo," as well as "Fanfare for the Common Man" and "Symphony No. 3." These works are celebrated for their open harmonies and evocation of the American landscape and spirit.

In addition to his compositions, Copland was a prolific writer and educator, authoring books such as "What to Listen for in Music" and "Music and Imagination." He also composed film scores, winning an Academy Award for "The Heiress" in 1949. Later in his career, Copland explored serial techniques, incorporating them into works like "Piano Quartet" and "Piano Fantasy."

Copland's influence extended beyond composition; he was a conductor and a champion of American music, earning the title "Dean of American Composers." He received numerous accolades, including the Pulitzer Prize, Kennedy Center Honors, and a Grammy Award. Aaron Copland passed away on December 2, 1990, in North Tarrytown, New York, leaving a lasting legacy in the world of classical music.
