Russian-born American pianist and composer, known for his stylistic mixture of Romanticism and modern experimentation—e.g., with a nine-note scale and with complex rhythms. In smaller forms his work was often coloured by Russian and Chinese motifs.

The son of the composer Nikolay Nikolayevich Tcherepnin, he studied at Tiflis (Tbilisi), Georgia, and later at the Paris Conservatory. In 1937 he married the Chinese pianist Ming Lee, with whom he subsequently gave concerts. Between 1934 and 1937 he visited China and Japan, establishing a firm in Tokyo for the publication of works by Japanese and Chinese composers. From 1949 to 1964 he taught at DePaul University, Chicago. His compositions include the opera The Farmer and the Fairy (1952), the ballet La Femme et son ombre (1948; The Woman and Her Shadow), and a concerto for harmonica and orchestra.
