was a Norwegian composer. He is best known for his lyrical work for piano Frühlingsrauschen (Rustle of Spring, 1896). He was often compared to Edvard Grieg and regarded as his successor.
He studied music first in Christiania (now Oslo) before going to Germany, where he studied at the conservatory in Leipzig under Salomon Jadassohn and fell under the musical influences of Wagner and Liszt. He lived in Germany for much of his life, but received regular grants from the Norwegian government. In 1921–22 he went to the United States of America to teach composition for a season at the Eastman School of Music in Rochester, New York.
Sinding's publishers required from him piano and chamber music, which had broader sales than the symphonic works he preferred. His own instrument was the violin. The large number of short, lyrical piano pieces and songs that Sinding wrote has led to many seeing him as the heir to his fellow countryman, Edvard Grieg, not so much in musical style but as a Norwegian composer with an international reputation. Sinding is best remembered today for one of his piano works, Frühlingsrauschen (Rustle of Spring, 1896). Among his other works are four symphonies, three violin concertos, a piano concerto, chamber music, songs and choral works to Norwegian texts, and an opera, Der Heilige Berg (The Holy Mountain, 1914).
