Percy Grainger was known during his lifetime as a virtuoso pianist and arranger of popular English folk song. His primary contribution to music, however, lies in his prolific output as a composer of expert and highly original works. Grainger's early years were spent in Melbourne where he studied first with his mother, and later with Louis Pabst. From 1895-1899 he attended the Hoch Conservatory in Frankfurt, Germany, and then settled in London in 1901. The next 10 years or so were devoted to a combination of concert touring and folk song collection. Grainger's early reputation was as a brilliant and eccentric pianist, and it was this talent that not only provided his income for the rest of his life, but also brought him into contact with other composers. Grieg and Delius, in particular, had great influence on Grainger's development of a sympathy and sensitivity toward unique national and folk styles. In 1914, Grainger moved to New York, beginning a long career as a composer, arranger, collector of folk music, and educator; he became an American citizen in 1918. In 1925 and 1927 he collected and published over 200 Danish folk songs, and returned to Australia in 1924, 1926, and from 1934-1935 in order to establish a Grainger Museum at the University of Melbourne devoted to ethnomusicological research. His final years were spent completing and arranging his earlier works and trying to develop a workable form of his "free music" using primarily theremins, one of the earliest electronic instruments. The project remained incomplete, and Grainger died embittered and in relative obscurity, known only for a handful of light works that he referred to derogatorily as his "fripperies."
Early in his life, Grainger rejected the central European tradition of Western classical music, seeking instead a "democratic" music that was more closely related to natural sounds, speech, and world music. In his quest to assimilate as much unique musical culture as possible, Grainger became one of the first ethnomusicologists to use the wax cylinder phonograph in the collection and transcription of indigenous music. His arrangements of many of these are among the best ever done, capturing not only the melodies and harmonies, but also the timbres, inflections, and performance styles of each individual piece. In his own compositions, Grainger experimented with nontraditional rhythms, forms, and instrumental combinations in an attempt to create what he called "free music." He also created a large body of more traditional works and arrangements intended for more popular consumption, motivated, no doubt, by his experience with the Edwardian music hall and later with the U.S. Army Band .
