This melody is the most popular to come from Oscar Straus' 1907 operetta of the same name, although it was called "Ein Walzertraum" in the original German. The work is aptly titled, as it has a lilting, dreamlike quality. This arrangement by Floyd Harris is for Alto Clarinet and Piano. Arrangments for Flute, Clarinet, Alto Saxophone, Tenor Saxophone, and Violin are available from the publisher.
