Norwegian folk music; but, in addition to being so conspicuously Norwegian, his genius was so universal that he very quickly rose to international eminence. Johan Svendsen (1840—1911) was a master of symphonies and rhapsodies. Ludwig Mathias Lindemann (1812—1887) collected and published more than one thousand Norwegian folk melodies. His work has been continued by Catharinus Elling, Johan Halvorsen, O. M.Sandvik, and others. Chris- tian Sinding (1856— ) has produced symphonies, compositions for the piano, and chamber music. Of other eminent musicians we may mention Hjalmar Borgstrom (1864—1925), Johannes Haarklou (18471925), Gerhard Schjelderup (1859—1933), and Eyvind Alnezs (1878—1931). Gerhard Schjelderup and O. M. Sandvik have published a comprehensive work in two volumes on the history of Norwegian music: Norsk Musikhistorie. Outstanding names among the younger gener- ation of living composers are: Johan Backer-Lunde, Halvdan Cleve, Arne Eggen, Torolf Voss, Bjarne Brustad, Eivind Groven, Fartein Valen, Odd Griner- Hegge, Leif Halvorsen, W. Huus-Hansen, Sverre Jordan, David Monrad-Johansen, J. L. Mowinckel Junr., Per Reidarson, M. M. Ulfrstad, Harald Szeverud, Irgens Jensen and Arild Sandvold. There is as yet no permanent opera in Norway, but operas have been produced at the National- theatret of Oslo and by a number of smaller theatres in various towns. The premier musical society is the Filharmonisk 74
