Arvo Pärt (11 September 1935) is an Estonian composer of classical and sacred music. Since the late 1970s, Pärt has worked in a minimalist style that employs his self-invented compositional technique, tintinnabuli. His music is in part inspired by Gregorian chant. Pärt has been the most performed living composer in the world for 5 consecutive years. Arvo Pärt was born in Paide, Järva County, Estonia. His musical studies began in 1954 at the Tallinn Music Secondary School, interrupted less than a year later while he fulfilled his National Service obligation as oboist and side-drummer in an army band.
