Named for Arvo Pärt (1935– ), Estonian-born composer. Until 1968, Pärt composed mainly serially. Since that year his music has evolved into what he terms a “tintinnabular” style, which is much influenced by medieval plainsong and organum. The calmness and linear clarity of the composer’s recent music, which is often compared to that of Benjamin Britten {see planet  (4079)}, have much affected the discoverer. (M 16593) _ _.
