John Alden Carpenter (February 28, 1876 – April 26, 1951) was an American composer.
Carpenter was born in Park Ridge, Illinois on February 28, 1876, and raised in a musical household. He was educated at Harvard University, where he studied under John Knowles Paine, and was president of the Glee Club, also writing music for the Hasty-Pudding Club. Showing great promise as a composer, he journeyed to London to study under Edward Elgar, and finally succeeded in studying with him in Rome in 1906, later returning to the United States to study under Bernhard Ziehn in Chicago through 1912. It was there he earned a comfortable living as vice-president of the family business, a shipping supply company, from 1909 to his retirement in 1936. After his retirement, he spent much of his time composing. Carpenter served as Chairman of the Board of Children's Home Society of Illinois and a life trustee of the Children's Home Society of Illinois Foundation. He died in Chicago on April 26, 1951.
Carpenter's compositional style was considered to be mainly "mildly modernistic and impressionistic"; also, many of his works strive to encompass the spirit of America, including the patriotic The Home Road and several of his works are jazz-inspired. He composed three ballets:Krazy Kat: A Jazz Pantomime, based on the Krazy Kat comics, was premiered at the New York Town Hall on 20 January 1922, and was the first work by a concert composer to use the word 'jazz' in its title; possibly his best-known is Skyscrapers (1926), set in New York (it premiered at the Metropolitan Opera), but equally inspired by his native Chicago.
One of his most famous works was 1914's impressionistic orchestral suite Adventures in a Perambulator. It was recorded in stereo in 1956 by Howard Hanson and the Eastman-Rochester Orchestra for Mercury Records, which initially released it on LP; Philips later reissued the recording on CD. In 1932, Carpenter completed The Song of Faith for the George Washington bicentennial. His first symphony (Symphony No. 1, in C) was premiered in Norfolk Connecticut in 1917 and revised for the 50th anniversary of the Chicago Symphony Orchestra, who performed it on October 24, 1940. Bruno Walter premiered his second symphony with the New York Philharmonic in 1942. He also wrote many piano pieces and songs, including the song cycle Gitanjali, with poems by Rabindranath Tagore.
