Gustav Lange (13 August 1830 – 20 July 1889) was a German composer known mainly for his melodious salon music for the piano. He was born in Schwerstedt, near Erfurt, Prussian Saxony, in 1830, lived for many years in Berlin and died at Wernigerode in 1889.
Lange received initial musical training from his father on the piano and organ, followed by conservatory studies in piano, organ, thorough bass, and composition – probably at the Royal Institute for Church Music in Berlin. His teachers included August Wilhelm Bach, Eduard Grell, and Albert Löschhorn.
Encouraged by the success of some 1860s compositions, Lange produced a large number of works, most of which were light and popular piano pieces of which he wrote around 500. Edelweiss, op. 31 and Blumenlied op. 39 (known in English as "Flower Song") are perhaps two of his best-known works today. A contemporary English source says: "Many of these pieces are very pleasing and pretty in character, but they are not marked by any very striking features." [Wikipedia]
