Christian August Sinding was a Norwegian violinist and composer born in 1856. He first studied music in Oslo then went to Leipzig, Germany, where he studied at the conservatory. In 1920 he came to the U.S. to teach composition at the Eastman School of Music in Rochester (New York.) He wrote a large number of short piano pieces and songs, one of which he is best remembered for (Rustles of Spring, 1896.) Sinding later spent much of his life in Germany. He also wrote a suite for violin which Heifetz used to play often. Among his larger works are three symphonies, three violin concertos, a piano concerto, choral works, and an opera (The Holy Mountain, 1914). For political reasons, his music is seldom heard today, even in his native Norway. Sinding died in 1941.
