Recently there has been a revival of interest in the music of Richard Strauss, and in Britain more attention has been paid to his lesser-known works. The symphonic poems such as Don Juan and Till Eulenspiegel, along with operas such as Salome, Etektra and Der Rosmkavalier, have never lapsed from the performance and recording repertoires. But the undeserved neglect of pieces such as the Duett-Concertino for clarinet and bassoon, and operas that rarely reach the stage in this country, such as Die Frau ohne Schatten, has begun to be remedied. A new development which can be seen as both cause and effect of this revival is the appearance of books in English dealing with Strauss and his music. These include recent reissues of Norman del Mar's three-volume Richard Strauss: a Critical Commentary on his Life and Works (1962–72, reprinted with corrections 1978) and Michael Kennedy's Master Musicians volume reissued with additional material in 1988. The study by Willi Schuh, whom Strauss chose as his biographer, was issued in 1982 in an English translation by Mary Whittall entitled Richard Strauss: a Chronicle of the Early Years.
